| Research Abstract |
We developed a new method to estimate the location of a magma head in a volcano conduit. It utilizes that gravity should change as magma goes up and down in the conduit. The gravity data after eliminating groundwater disturbance enables us to determine the head height as geometrical parameters of the conduit is successfully estimated with the cosmic ray radiography. The result is essentially important to discuss how magma movement in the shallower part is related to the volcanic activity.
