Mount Asama, Japan - February 4th, 2009

On February 2nd, Japan’s Mount Asama volcano, located in the center of Honshu Island, underwent a minor eruption.

The northwestern part of Tokyo is visible at the upper right. West of this area, Mount Asama can be seen, as can Mount Fuji (almost due south of Mount Asama, in the lower right quadrant).

Japan’s Kyodo news agency reported that the volcano, on the border of Japan’s Gunma and Nagano prefectures, produced ash showers that reached as far as Tokyo.

Officials warned of the possibility of large deposits within a 4-kilometer radius of the crater, at 2,568 meters above sea level.

Smoke was observed moving southeastward, and ash showers were experienced in Tokyo, Saitama, Kanagawa and Chiba prefectures, as well as in Karuizawa in Nagano Prefecture and Tomioka in Gunma Prefecture.

At the time of the eruption, the area was cloud-covered. In this cloud-free image, taken two days later, there is no evidence of smoke.
