Mt Fuji Predicted Eruption Data

It has been more than 300year since MT Fuji last erupted (1707 Hoei eruption which latested for 2 weeks).  It is presently dormant but the magma inside remains active.  Historical Records show that there have been previous dormant periods of Mt Fuji (from 1083-1435, 1511-1704) and eruptions have sometimes been linked to earthquakes in the Kanto area (although there was no eruption during the last large Kanto earthquake in 1923).

The most comprehensive information on MT Fuji and its potencial Eruption information is in a pdf published by the Mt Fuji Sabo office whose work is to predicted and attempt to reduce the impact of the next eruption.

This explains the history of MtFuji as well as the counter-measure taken to reduce the impact of a Future eruption.  At the end of a pdf is a brouchure which includes the predicted Ashfall from Mt Fuji which estimates 30cm of ash across Yokohma and approximately 10cm ashfall in Tokyo.

There is a great deal of info on MT Fuji on the MT Fuji Sabo website http://www.cbr.mlit.go.jp/fujisabo/ Though google translate maybe needed to view info in English. The website also includes CGI graphics of previous Mt Fuji Eruptions
