Mount Asama in JapanFebruary 2nd, 2009 - 2:17 pm ICT by Amrit Rashmisrisethi
Mount Asama, an active complex volcano in central Honshu , the main island of Japan, on the border of Gunma and Nagano prefectures. 2544 m and 8340 feet and the location 36.24°N 138.31°E / 2,568 m above sea level, it erupted most today. Previously eruptions occurred in 685, 1108, 1783, 1972, and 2004; lesser activity has been recorded on dozens of occasions. The eastern slope has a volcano observation station run by Tokyo University.
Scientists from Tokyo University and Nagoya University completed their first successful imaging experiment of the interior of the volcano in April 2007. By detecting sub-atomic particles called muons as they passed through the volcano after arriving from space, the scientists were able gradually to build up a picture of the interior, creating images of cavities through which lava was passing deep inside the volcano.
It is one of the 100 famous mountains in Japan. One of the largest and most active volcanoes in Japan, it erupted violently in 1783 and has frequent minor eruptions.
