Research Abstract

We analyzed eruption products of Fuji volcano etc, to find that the eruption styles (either explosive or effusive) are mainly determined by degree of degassing in shallow chamber as well as the eruption rate in the shallowest part of the volcanic conduit. We also carried out viscosity measurements on crystal-bearing magmas of MORBs, shoshonite etc, to evaluate the effect of crystal morphologies on the relative viscosities.
