Abstract:
Our society has faced a steep rise in economic and insured losses from natural hazards, especially weather related. Natural hazards in mountainous regions are closely related to the chute system diatribution and underground channels. Bedrock crevasses are not easy to measure because they are often overlain by the rhizosphere. In this presentation, we will present remote sensing imageries that are indicative of bedrock crack changes. In particular, we examined four 5x5 degree grid boxes surrounding respectively El Chichon, Mt. St. Helens, Mt. Pinatubo and Mt. Fuji. It is found that surrounding the Fuji mountains, ground water increases from 2002-2013 are out of natural sync with precipitation and other indirect indications of bedrock cracks. So, the increase of natural hazard of this region is expected to be more frequent in the upcoming several years
