Imagine coming back from a camping trip in the desert. Then a few months later you notice in your photos from the trip that you camped inside a giant impact crater so big that no one documented it before. Could it happen?

During several trips to the Black Rock Desert, mostly while supporting the Stratofox Aerospace Tracking Team for suborbital space rocket launch efforts, Ian Kluft KO6YQ noticed some oddities in rock formations. He had a little experience with volcanoes, and some rocks in the area looked unusual. There seemed to be some lava here and there – but where was the volcano? He observed that even a large caldera should have mostly volcanic rocks. He then noticed some curved geographic structures in satellite imagery which made him curious if it might be an impact crater.

A TV documentary about meteor impacts mentioned some characteristics of impact craters. He went to the Internet to learn more. He noticed some of his own pictures of the area had cone shaped structures which might be “shatter cones” due to an impact shock wave that passed through the rocks. Discussion with others produced suggestions and volunteers who joined the effort. More circular features in satellite photographs were found. Igneous dikes through white layers of rock had been described and were visible in many photos.

The possible impact crater is 30 miles (48 km) wide east-to-west and 40 miles (64 km) north-to-south centered around 40.984045 N, 118.916016 W. That is in northwestern Nevada halfway between Reno and the Oregon border. The apparent ancient geological structure is so old that much of it is eroded away. The forces that eroded the Black Rock Desert itself, whether glacier or stream, have apparently cut through the crater rims and floor to do it.

Following an expedition to the area in late January, more possible shatter cones were observed in one of the rock samples collected. These are only formed by the shock wave of an impact event or nuclear explosion. The nearest nuclear test was underground at Sand Springs Range in central Nevada. Atmospheric tests at the Nevada Test Site were at the southern, and opposite, end of the state. So that points toward an impact if confirmed. But professional geologists will want to have the final word on confirming them.

In addition to shatter cones, rock samples were thought to contain shocked quartz because the criss-cross fractures looked like examples in online documents. But this group of volunteers doesn’t have equipment for proper photography of shocked quartz. If found, that would be another way to prove the impact origin of the rocks.

Columnar jointed columns hundreds of feet tall appear on some bluffs in locations that appeared consistent with part of a slowly cooling crater floor. But that alone only helps as part of a bigger picture, because volcanoes can have lava cool in columnar joints as well.

They also found local geological studies which described oddities which could be explained by an impact event. Layers of rocks in the mining district called Sulphur left geologists with a mystery about the cause of chemical alterations since 1980. The group compared it with information in online geological texts like “Traces of Catastrophe” by Dr Bevan M French of the Smithsonian Institution. Layers of impact ejecta seemed to explain the rock layers better than the previous theory about acid uniformly cooking the rocks across the region, and only in one layer of rocks. A separate 1980 study 40 miles away identified an immense air-fall tuff layer in the Soldier Meadows area as having been deposited in a single unit, yet couldn’t locate the volcano which produced this enormous volume. Fault diagrams published online by a mining operation at Sulphur on the edge of the circular structure from the satellite photo also look like curved terraced faults in the wall of a crater.

The mining geologists who wrote papers from 1980 to 2002 had not mentioned the possibility of a crater. But they were each gathering single puzzling pieces of information. A larger image seemed to be forming when putting the pieces together. The group hopes the information will be helpful to geologists who do further work in the region.

The theory hasn’t been put to any test by professionals yet. Some responses point out that the elliptical region reported as the possible impact crater could also be the volcanic caldera that the 1980 study was looking for. If so, such a large volcanic caldera would still be a significant discovery for the region.

This will remain officially a mystery for a while until the professional geologists get to study it. There is a lot of information available online for those who are interested.

200,000 litres of oil leaked into waters off the coast of Brisbane from the Pacific Adventurer when their fuel tanks were damaged in rough seas on Wednesday. The figure is about ten times higher than the original estimate of twenty thousand litres of oil. The devastating diesel oil spill has spread along 60 kilometres (37 miles) of the Queensland coast. In addition, 31 containers with 620 tonnes of ammonium nitrate fertiliser flew overboard during the violent storm.

Questions are being asked why the Hong Kong cargo ship was out in seas with nine meter waves caused by Cyclone Hamish, a Category 5 tropical cyclone, as well as why the fertiliser containers were not properly secured. One of the overboard containers ruptured the hull of the Pacific Adventurer, causing between 30 to 100 tonnes of oil to spew from the severely damaged ship.

If the ammonium nitrate mixes with the heavy oil, an explosion could occur. None of the containers have been recovered. Some of these may float, but it is believed that they may have sunk which then may cause algal blooms.

Disaster zones have been declared at Bribie and Moreton Islands, and along the Sunshine coast.

The vessel’s owner, Swire Shipping, reported that a second leak began on Friday, when the ship began listing after docking at Hamilton for repairs. “As full soundings of the vessel’s tanks were being taken at the port to determine how much oil had leaked from the vessel, a small quantity of fuel oil escaped from the Pacific Adventurer,” it stated. The ship was brought upright, and a recovery vessel was used to suck up the oil from the water. The leak produced a 500m-long oil slick down the Brisbane River. Booms were placed around this oil spill so that a skimmer could clean up the second spill.

Swire Shipping could face clean up costs of AU$100,000 a day as well as fines up to AU$1.5million (US$977,000; £703,000) if found guilty of environmental breaches or negligence.

Sunshine Coast beaches are slowly starting to be reopened. The beach of Mooloolaba was still closed following reports of burning sensations from swimmers. 12 beaches remain closed; however, 13 have been reopened.

Over 300 state government and council workers are using buckets, rakes and spades in the clean up effort. Sunshine Coast Mayor Bob Abbott says the majority will be gone by Sunday afternoon. The full environmental impact on wildlife is not yet known. One turtle and seven pelicans have been found covered in oil.

There are concerns that the drinking water of Moreton Island is at risk, as the island uses water from the underground water table near the oil spill site.

“Every bucketload of contaminated sand has to be removed from the island by barge, and each bucketload from a front-end loader weighs about one tonne. It’s just an impossible task,” said Mr Trevor Hassard of the Tangalooma Dolphin Education Centre.

The commercial fishing industry has suffered from the incident. Trawlers won’t resume operations until Sunday evening, and any catches will be tested for human consumption.

Joint Task Force Guantanamo (JTF-GTMO) reported a fifth Guantanamo captive, named Abdul Razzak, died in captivity, on December 30, 2007.

JTF-GTMO asserted that Razzak had complained of abdominal pains in September 2007, and had begun to receive cancer therapy in late October 2007. JTF-GTMO estimated that he was born in 1939.

According to the JTF-GTMO press release that announced his death:

Abdul Razzak was assessed to be an experienced jihadist with command responsibilities and was assessed to have had multiple links to anti-coalition forces. He was detained in Guantanamo as an enemy combatant, consistent with the international law of Armed Conflict.

Abdul Razzak was one of the few Guantanamo captives who continued to attend his Combatant Status Review Tribunal and his annual Annual Review Board hearings.

Abdul Razzak had disputed all but one of the allegations against him, at each opportunity, and had provided his JTF-GTMO interrogators and the officers who sat on his CSR Tribunal and ARB hearing with easily verifiable corroborated details. At each of his Administrative review the officers were unaware of the exculpatory details he had provided.

The one allegation that Abdul Razzak acknowledged was that he had been subjected to involuntary conscription, and had served the Taliban for three months out of every year for the five years they were in power before he fled Afghanistan. He had, however, not served in the Taliban’s armed forces, but had been a truck driver, delivering non-military supplies.

One of the main allegations against Abdul Razzak was that he had plotted to help free Taliban leaders. Abdul Razzak testified that, on the contrary, two years prior to al Qaeda’s attacks on September 11th, 2001, he and his son had played a key role in a successful plot to free three imprisoned senior Northern Alliance leaders, who he identified as “Ismail Khan, Haji Zahir, son of vice president Haji Qadir and General Qassim.” — Ismail Khan is currently the Minister of Energy.

Abdul Razzak testified that his son, one of the relatively few Afghans who was fluent in English, had been conscripted by the Taliban, so he could provide some computer support. His son had contacted anti-Taliban forces, secured funds to purchase a four-wheel drive vehicle. His son, using the trust the Taliban had placed in him, due to his computer support, had lead the three men out of their imprisonment. Abdul Razzak had driven the four by four. The vehicle was damaged by a land mine. Abdul Razzak’s hand was injured. His son lost a foot. But the Northern Alliance leaders were rescued.

Abdul Razzak testified that when they arrived in Iran the Afghanistan Council paid his living expenses. But, when Hamid Karzai assumed power, following the ouster of the Taliban, he was told that the pension would be discontinued, because Afghanistan now had a democratic government.

Abdul Razzak testified that he then returned to Afghanistan, where he was falsely denounced by a distant cousin named Mohammed Jan. Mohammed Jan’s branch of the family was engaged in a feud with his branch, that had lead to the death of his father, two uncles, and three of his sons.

Abdul Razzak was also accused of being a leader of anti-coalition forces, and of being a member of the Hezb-e-Islami Gulbuddin, an older militia, which was first founded to oppose the regime of Mohammed Daoud Khan, the politician who had ousted Mohammed Zahir Shah, the last King of Afghanistan, in 1973. In 1979 this militia split, and has been lead, since then, by Gulbuddin Hekmatyar. Gulbuddin Hekmatyar’s militia played a major role in the resistance to the Soviet occupation of Afghanistan. This militia acquired a reputation for ruthlessness, and disregard for civilian life.

Abdul Razzak testified that his only contact with the Hezb-e-Islami Gulbuddin militia was early in the war against the Soviets. He testified he was imprisoned for four and a half months in an underground pit. They had captured him because he had served as a driver for a member of the communist regime.

American intelligence analysts assert that, when Osama bin Laden was leaving Sudan, Gulbuddin Hekmatyar offered him sanctuary in the areas of Afghanistan under his control.

Although not part of the Northern Alliance the Hezb-e-Islami Gulbuddin militia fought with the Taliban, prior to their ouster. When the USA allied with the Northern Alliance and other resistance forces to oust the Taliban the Hezb-e-Islami Gulbuddin militia fought against the USA. In 2003 the Hezb-e-Islami Gulbuddin formed an alliance with the rump of the Taliban.

Abdul Razzak was also accused of being the Abdul Razak who had been the second in command of the Taliban’s 40-man unit, even though witnesses described Abdul Razak the commander as a much younger man, with a full black beard. Americans held five other men in Guantanamo named Abdul Razak.

In May, periodical cicadas with 17 years life cycle emerged on the East Coast of the USA after underground development as juveniles since 1996. Researchers and scientists worked to map and study the rare wave, and the locals prepared for the noisy event. First recorded in 1666, the Magicicada septendecim species recently emerged in 1979, 1996, this year, with a next wave due in 2030.

This week, Wikinews interviewed Chris Simon, an ecology and evolutionary biologist at University of Connecticut, about the cicadas.

((Wikinews)) What caused your initial interest in periodical cicadas?

Chris Simon: As an undergraduate student, I was interested in the formation of species so when I went to graduate school I looked for a study organism that was likely to be in the process of forming new species. I chose periodical cicadas because they are broken up into reproductively isolated broods (or year classes). Reproductive isolation leads to speciation so I planned to study biochemical differences among the broods.

((WN)) You study the emergence of the periodical cicadas. What do you study? What observations are you making?

CS: We record exactly where each cicada population emerges (using GPS automated mapping and crowd sourcing). We record the presence or absence of each of the three morphologically distinct species groups of periodical cicadas (Decim group, Cassini group, and Decula group). We collect specimens for DNA analysis. We look for cicadas coming up one and four years early and late. We dig up cicada nymphs and monitor their growth rates.

((WN)) What equipment do you use?

CS: Nets, shovels, automated GPS recorders, cameras, laptop computers, automated DNA sequencers.

((WN)) Do you study the periodical cicadas with anyone else? What is their role?

CS: Yes, there are a large number of people studying periodical cicadas in my lab and in other labs. My lab is made up of Research Scientists, Postdoctoral Researchers, a technician, graduate students, and undergraduates. Research Scientist John Cooley is the leader of the GPS mapping project; he invented the automated GPS recorder; he built our crowd-sourcing website, and he is instrumental in public outreach. Postdoctoral research David Marshall also participates in the mapping project and leads the part of the research related to the mapping of stragglers. John and Dave and Technician Kathy Hill all study periodical cicada mating behavior and conduct mating and hybridization experiments. One of my graduate students Beth Wade has participated in the nymph collections and will soon start genetic work involving genome wide association mapping designed to locate genes related to life cycle. My graduate student Russ Meister is studying the genes of the bacterial endosymbionts of cicadas. My current undergraduate honors student Erin Dwyer is also studying the development of Magicicada nymphs and is helping to design a lab exercise for college students around the eastern US to do the same. Many of my past undergraduate students have studied the biochemical genetics and development of periodical cicadas. See the Simon Lab website.

CS: We are collaborating with Teiji Sota at the University Kyoto and Jin Yoshimura at Shizuoka University in Japan. They are studying the phylogeography of Magicicada. We are collaborating with John McCutcheon of the University of Montana who is studying the endosymbiont genomes.

CS: We are also collaborating with ecologists Rick Karban and Louie Yang, both professors at UC Davis who have an interest in cicada population dynamics and nutrient cycling in the ecosystem.

((WN)) You studied the periodical cicadas in 1979 and 1996 too. What changes with time?

CS: I have studied periodical cicadas since I was a student back in 1974. What changes with time is increased human development constantly shrinking the patch size of cicada populations.

((WN)) What are your thoughts on the long life span of the periodical cicadas? Why could it be so? What advantages and what disadvantages does it have?

CS: Most or all cicadas have long life cycles compared to your typical annual insect. Examples have been found of two-year to 9-year cycles in different species. Periodical cicadas evolved an even-longer life cycle and I think that part of this relates to the evolution of their synchronized life cycles and peculiar safety-in-numbers strategy for survival. To become synchronized, periodical cicadas had to evolve an exact length life cycle and all adults would have to appear in the same year. Because the nymphs grow at different rates underground, a longer life cycle and a way of counting years must have evolved so that the individuals that get to the last nymphal (underground juvenile) stage first would wait long enough for all other individuals in the population to become ready to emerge.

((WN)) News reports mention this is ‘Brood II’ of the periodical cicadas. What are the distinctive features of this specific species and what is its full scientific name?

CS: The same species exist in multiple broods. No species is restricted to Brood II. The three species present in Brood II are: Magicicada septendecim, M. cassini, and M. septendecula. These same three species are found in every 17-year brood (except the farthest north which only has M. septendecim).

((WN)) At what depth do the cicadas juveniles live underground?

CS: Most live within the top foot of soil but some have been found deeper. We do not know if they go deeper in winter. We need to do much more digging to understand the nymphs.

((WN)) How do people prepare for the cicada emergence?

CS: Of course various people prepare in different ways. Ideally, everyone prepares by studying information available on the web (especially on our websites Magicicada Central and Magicicada.org).

((WN)) Do cicadas affect transport in the local area?

CS: No, not really. Occasionally individuals can be seeing flying across highways and sometimes they smash into cars.

((WN)) Do cicadas usually stay outside or do they also invade houses too?

CS: They stay outside. One might accidentally fly in through an open window but that would be rare.

((WN)) What do the cicadas eat?

CS: Cicadas suck xylem fluid (the watery fluid coming up from the roots of plants) in deciduous forest trees and herbs. Essential amino acids in the cicada diet are supplied by their bacterial endosymbionts. There are two species of endosymbionts. One makes 8 essential amino acids and one makes two essential amino acids.

((WN)) Do cicadas damage crops or city vegetation? What damage?

CS: Cicadas do not chew leave so they do not damage crops like other insects. They can inflict some damage by their egg laying. Cicadas lay eggs in pencil-sized tree branches. If there are not enough branches available, too many female cicadas may lay eggs in a single branch weakening it and making it susceptible to breakage by wind. This can sometimes cause damage in fruit orchards. If the branches break, the eggs die so this behavior is selected against by natural selection.

((WN)) Thank you.

CS: You’re welcome. I am happy to have this opportunity to communicate with your readers!

It has emerged that the 33 Chilean miners trapped underground after the mine they were working in collapsed could be brought to the surface in a shorter time than was initially feared. While officials publicly announced that the men would not be brought to the surface until Christmas, sources inside technical meetings have revealed that they could in fact be on the surface by early November. The news comes as families were allowed to speak by radio-telephone to their trapped loved ones on Sunday. Over the weekend, video images filmed by the miners emerged showing the miners playing dominoes at a table and singing the Chilean national anthem. The miners also used the camera to send video messages to their families on the surface, saying that they regularly broke into tears, but were feeling better having received food and water.

The grainy nightvision images, filmed on a high definition camcorder that was sent down a small shaft to the mine, show the men in good spirits, chanting “long live Chile, and long live the miners.” They are unshaven and stripped to the waist because of the heat underground, and are seen wearing white clinical trousers that have been designed to keep them dry. Giving a guided tour of the area they are occupying, Mario Sepúlveda, one of the miners, explains they have a “little cup to brush our teeth”, and a place where they pray each day. “We have everything organized,” he tells the camera. Gesturing to the table in the center of the room, he says that “we meet here every day. We plan, we have assemblies here every day so that all the decisions we make are based on the thoughts of all 33.” Another unidentified miner asks to rescuers, “get us out of here soon, please.” A thermometer is shown in the video, reading 29.5C (85F).

As the film continues, it becomes evident that the miners have stuck a poster of a topless woman on the wall. The miners appear shy, and one man puts his hand to his face, presumably dazzled by the light mounted on the cameraman’s helmet. One miner sent a message to his family. “Be calm”, he says. “We’re going to get out of here. And we thank you from the bottom of our hearts for your efforts.” Another said that the miners are “sure that there are people here in Chile that are big people, that are powerful people, that are intelligent people, and they have the technology and they will all work together to get us out of here.” Speaking to the camera, one says: “we have had the great fortune that trapped in this mine there are good, professional people. We have electricians, we have mechanics, we have machine operators and we will let you know that while you are working to rescue us on the surface, we are down here ready to help you too.” It has been reported that Mario Gómez, 63, has become the group’s “spiritual leader”, having worked in the mines for over fifty years. He has requested that materials to build a shrine be sent down to the cavern.

Upon seeing the video in a private screening, family members, who are living in a small village of tents at the entrance to the San José copper-gold mine—which they have named Camp Hope—were elated. “He’s skinny, bearded and it was painful to see him with his head hanging down, but I am so happy to see him alive”, said Ruth Contreras, the mother of Carlos Bravo, who is trapped in the mine. The video, of which only a small portion has been released to the public, shows the miners, many of them wearing helmets, cracking jokes and thanking the rescuers for their continued efforts. The supplies are being sent to the men through a small shaft only twelve centimeters wide, and a laboratory has been set up with the purpose of designing collapsible cots and miniature sandwiches, which can be sent down such a narrow space.

CNN reported on Friday that “officials are splitting the men into two shifts so one group sleeps while the other works or has leisure time .. On average, each man has lost 22 pounds (10 kilograms) since they became trapped three weeks ago, and dehydration remains a threat. But a survey of the men indicates that at least nine miners are still too overweight to fit through the proposed rescue shaft. Initially, the miners survived by draining water from a water-cooled piece of equipment. To stay hydrated in the 90-degree mine, each miner must drink eight or nine pints of water per day.”

But while there are jubilant celebrations on the surface that the miners are alive, officials are now nervous that the miners could become depressed, trapped in a dark room the size of a small apartment. Chilean health minister Jaime Mañalich said that, on the video, he saw the telltale signs of depression. “They are more isolated, they don’t want to be on the screen, they are not eating well”, he said. “I would say depression is the correct word.” He said that doctors who had watched the video had observed the men suffering from “severe dermatological problems.” Dr. Rodrigo Figueroa, head of the trauma, stress and disaster unit at the Catholic University in Santiago, Chile, explained that “following the euphoria of being discovered, the normal psychological reaction would be for the men to collapse in a combination of fatigue and stress … People who are trained for emergencies – like these miners – tend to minimize their own needs or to ignore them. When it is time to ask for help, they don’t.” NASA has advised emergency workers that entertaining the miners would be a good idea. They are to be sent a television system complete with taped football matches. Another dilemma facing Mañalich is whether the miners should be permitted to smoke underground. While nicotine gum has been delivered to the miners, sending down cigarettes is a plan that has not been ruled out.

With the news that drilling of the main rescue tunnel was expected to begin on Monday, officials have informed the media that they hope to have the miners out of the mine by Christmas—but sources with access to technical meetings have suggested that the miners could actually be rescued by the first week of November. A news report described the rescue plan—”the main focus is a machine that bores straight down to 688m and creates a chimney-type duct that could be used to haul the miners out one by one in a rescue basket. A second drilling operation will attempt to intercept a mining tunnel at a depth of roughly 350m. The miners would then have to make their way through several miles of dark, muddy tunnels and meet the rescue drill at roughly the halfway point of their current depth of 688m.” Iván Viveros Aranas, a Chilean policeman working at Camp Hope, told reporters that Chile “has shown a unity regardless of religion or social class. You see people arriving here just to volunteer, they have no relation at all to these families.”

But over the weekend, The New York Times reported that the “miners who have astonished the world with their discipline a half-mile underground will have to aid their own escape — clearing 3,000 to 4,000 tons of rock that will fall as the rescue hole is drilled, the engineer in charge of drilling said Sunday … The work will require about a half-dozen men working in shifts 24 hours a day.” Andrés Sougarret, a senior engineer involved in operating the drill said that “the miners are going to have to take out all that material as it falls.”

The families of those trapped were allowed to speak to them by radio-telephone on Sunday—a possibility that brought reassurance both the miners and those on the surface. The Intendant of the Atacama Region, Ximena Matas, said that there had been “moments of great emotion.” She continued to say that the families “listened with great interest and they both felt and realized that the men are well. This has been a very important moment, which no doubt strengthens their [the miners’] morale.” The phone line is thought to be quite temperamental, but it is hoped that soon, those in the mine and those in Camp Hope will be able to talk every day. “To hear his voice was a balm to my heart … He is aware that the rescue is not going to happen today, that it will take some time. He asked us to stay calm as everything is going to be OK … He sounded relaxed and since it was so short I didn’t manage to ask anything. Twenty seconds was nothing”, said said Jessica Cortés, who spoke to her husband Víctor Zamora, who was not even a miner, but a vehicle mechanic. “He went in that day because a vehicle had broken down inside the mine … At first they told us he had been crushed [to death].”

Esteban Rojas sent up a letter from inside the mine, proposing to his long-time partner Jessica Yáñez, 43. While they have officially been married for 25 years, their wedding was a civil service—but Rojas has now promised to have a church ceremony which is customary in Chile. “Please keep praying that we get out of this alive. And when I do get out, we will buy a dress and get married,” the letter read. Yáñez told a newspaper that she thought he was never going to ask her. “We have talked about it before, but he never asked me … He knows that however long it takes, I’ll wait for him, because with him I’ve been through good and bad.”

According to the Alcohol Tobacco and Firearms Agency or ATF, at least 686 sticks of dynamite and at least 30 pounds of ammonium nitrate were stolen from Gold Mountain Mine Company in Big Bear City, California located in San Bernardino County. Fuel oil and mining equipment are also among the items stolen. When combined, the fuel oil and ammonium nitrate become combustible and authorities fear what could be done with the explosives.

“The obvious concern is someone stole it, and what are they going to do with it? This is a quantity of explosives that could do significant damage. We need to recover these items,” said John D’Angelo, spokesman for the ATF.

The thieves cut locks on the gate that leads to the facility and then cut the locks on a metal storage bin and stole its contents and everything inside the facility. The man responsible for mining operations in the area does so as a hobby. The robbery was reported on May 3.

“We urge anyone who has information about this theft to contact ATF and the San Bernardino Sheriff’s Department. Our job is to keep the public safe. We take the theft of explosives extremely seriously, and we will relentlessly follow up every lead until we solve the case,” said John A. Torres who is the special agent in charge of the ATF in Los Angeles.

Authorities have offered a $25,000 reward for information about the crime that leads to an arrest and conviction.

Fuxin city (???; pinyin: Fùx?n shì) – An underground explosion in a mine in China’s northeastern Liaoning Province has left over 200 miners dead.

Current figures say 203 miners were killed, and another 22 were injured with 13 miners still missing. The blast occurred at 3:49pm local time on Monday afternoon.

The explosion, 242m underground, is believed to have been caused by gas igniting.

This morning a rescue team arrived at the site in Fuxin to attempt locate survivors and treat injured.

China has a history of major mining accidents. Last November, 166 miners died in an explosion in mine in Chenjiashan mine in Shaanxi province. In 2004, a official figures show that 5,000 workers died in accidents in mines, 35% of the world-wide death toll in coal mines.

A group of volcanologists from the UK and USA have traveled to North Korea to assist them with conducting scientific investigations and installing equipment near the volcano Mount Paektu.

Wikinews interviewed Dr. Robert Kelly of Pusan National University (PNU) in South Korea, who specialises in security and diplomacy and Dr. Jim Gill from the University of California who has visited the Chinese side of Mount Paektu.

((Wikinews)) Given that the UK, USA have strained political relations with North Korea, what is the purpose of these scientists working together?

Dr. Robert Kelly: Mt Paektu erupted massively about 1100 years ago and has been dormant since. Recently there has been seismic activity, and should it explode again, it could be gigantic — and devastating. It is everyone’s interest in East Asia to know about such a possibility, so this kind of cooperation can be above politics. But it is also always good to engage North Korea to try to draw them out. Such engagement can occur in nonpolitical, technical areas like this most easily.

((WN)) Does North Korea understand that it needs the specialism of British and American scientists to plan for when the volcano erupts?

RK: It does. North Korea does actually engage in various track II programming, including student and administrative exchanges. This is not well-known due to the nuclear issue however. The North Korean government is aware of its technological backwardness, and they often dangle concessions to other states in exchange for tech transfers like this.

((WN)) The North Korea underground nuclear test site is very close to the volcano, do you think this affected North–South Korean relations?

RK: Not very much. It does upset South Koreans somewhat, because Mt. Paektu is actually [a] national landmark. It is the mythological birthplace of the Korean people. And there is some scientific concern that major seismic activity could impact nuclear facilities.

((WN)) Do you think that the field work being carried out by the scientists, being near a militarised border is very difficult?

RK: No, because it is in the interest of all local parties — NK, Chinese, even Russian — that Mt. Paektu is properly monitored. Indeed, I could imagine that, behind the scenes, the Chinese pushed North Korea toward this cooperation, as this is somewhat unusual for NK.

((WN)) May the North Koreans be wary and suspicious of their British and American counterparts, given the secretiveness of the state?

RK: Absolutely. I have been to NK, and I can say positively that the scientists will be monitored and accompanied at all times they are away from their hotels. They will also be isolated from the NK wider population. They will only interact with specially chosen minders who speak excellent English and have proven their loyalty to the state. And there will be security personnel with them at all times outside their hotels too.

((WN)) Do you think that Western scientists collaborating together with the North Koreans could set as an example of political things to see in the future?

RK: Not really. I hope so, but North Korean^[sic] has a tendency to pretend to open itself, and then to re-close after it gets what it wants. All sorts of interaction with North Korea gets hyped as ‘a new beginning’ or a ‘historic opening,’ only to come to naught. That does not mean it could not happen, just that I am skeptical. Instead, NK is likely to continue to interact when and where it has certain specific needs, as in this case. And that interaction will be tightly monitored. Fifteen years [ago], at the start of the Sunshine Policy by SK, there was hope that increased interaction would grow organically and slowly open up NK. That was the spirit behind the Kaesong industrial zone. But in fact, the North Koreans tightly controlled Kaesong to capture its gains and limit spillovers. I imagine the same will happen here.

((WN)) Do natural hazards pay attention to international political differences?

Dr. Jim Gill: Of course not.

((WN)) Is there a high risk and increased seismic activity in relation to Mount Paektu?

JG: Not currently. There was unrest at the volcano during 2002–05 but it has returned to normalcy.

((WN)) Would an eruption of Mount Paektu have consequences for multiple countries?

JG: Yes. The most likely widespread consequence will be an interuption of air traffic between North Asia and North America and Europe. More locally, the tourist industry on the Chinese side of the border will be very impacted. Most ash fall will be in the DPRK.

For perspective, there was an extremely large eruption of the volcano at about 940 AD — one of the largest historical eruptions anywhere on Earth. It is uncertain how often it has erupted since, and how large the eruptions were, but nothing has been big enough to cause serious problems scores of kilometers away. So yes there is risk — it is large mountain with a long history of eruptions — but nothing indicates a high level of concern now.
