Research Abstract

We estimated eruption mechanism and underground structure of the Anatahan Volcano, in the Northern Mariana Island, using geodetic method such as GPS survey ground Tilt measurement, and In-SAR analysis. The magma chamber of the volcano is existed at 5km below ground and 2km off west of the island, and conduit rose obliquely to the east eruptive crater. Also we could estimate the thickness of the volcanic ash fall using In-SAR analysis.
