JAPAN HAS 104 ACTIVE VOLCANOES

The 1,421-m (4,662-ft) Mount Shinmoedake is a part of the Kirishima volcano complex comprised of 20 active volcanoes

Mount Shinmoedake is located on the border of the

Miyazaki and Kagoshima prefectures

In the previous four months, Miyazaki prefecture had also suffered from an epidemic of the H5N1 bird flu, and a foot-and-mouth epidemic that is expected to cause ~ $ 2 billion in economic losses for the local livestock industry.

The inflation of the Shinmoedake volcano that eventually culminated in an

eruption had been underway since December 2009

May 10, 2010 to Present: ~6 million m3 (0.006 km3) of

magma in a reservoir at 6 km depth ~10 km WNW from

Shinmoedake and another 1 million m3 (0.001 km3) of

magma at 3 km depth under the Shinmoedake cone itself.

The eruption produced lava fountains, andesitic lava flows, and ash emissions that reached a height of nearly 5 miles (7.5 km)
