From a combination of historical records and ash layers, it appears that Changbai wakes up every 100 years or so, the last time in 1903. Rather alarmingly, about 1000 years ago, the volcano had an eruption that was one of the largest of the past few thousand years, rivaling the 1815 eruption of Tambora in Indonesia. It spread ash over 33,000 square kilometers of northeast China and Korea, and dumped 5 centimeters of ash on Japan. (So that this post is not taken as being alarmist, there is no indication that an eruption is imminent.) I'm not going to dwell on the volcanology here, perhaps at a later date. In a nutshell, on a Volcanic Explosivity Index (VEI) of 8, only a few 7's have occurred in the last 11,500 years, and the eruption of Changbai 1000 years ago was one of them. It erupted nearly 100 cubic kilometers of ash.
I think that the importance of this Science article is the spotlight that it shines on science as a way to transcend political and philosophical borders. The North Koreans and Chinese have already established a collaboration to monitor this dangerous volcano, and in September, they brought in two westerner geologists from the U.K. to visit the site. They are James Hammond from Imperial College, and Clive Oppenheimer from Cambridge. They were accompanied by Richard Stone, the author of the article. This "unprecedented encounter was facilitated by two nongovernmental organizations: Pyongyang International Information Center on New Technology and Economy, or PIINTEC, based in Pyongyang, and the Environmental Education Media Project in Beijing." The three were impressed with the North Korean scientists and facilities, and with the budding collegiality-- Chinese scientists may be doing research at Paektu in North Vietnam next summer. The deputy director general of DPRK's Earthquake Administration has said "we welcome scientists with open arms" (to build up the capability to monitor the volcano and forecast eruption scenarios." Hats off to all who made this work, including Hans-Ulrich Schmincke who managed to get in there in 1993!
Over the past centuries, there have been only a few ways to transcend the political and military tensions that are all to prevalent and dangerous in the world. They have been (1) arts and culture; (2) humanitarian aid; and (3) science, particularly in the area of natural hazards. For another program, very relevant to "Mount Doom", take a look at Cities on Volcanoes, a Commission of the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI).
