Research Abstract |
Volcano inflations generated by ascent of magma with gas bubbles are investigated. Ascent of magma with gas bubble growth due to diffusive flow causes volcano inflation with a constant rate or temporally accelerated change. For the case of a large slug rising up in viscous melt, volcano inflation turns to deflate when the slug approaches to the ground surface. Finite element calculations indicate that the volcano inflation rate becomes small after the magma head goes above a geodetic station.
