The aim of my research is to mitigate disasters caused by earthquakes and volcanic activities.

We can estimate fault displacements and accumulation of magma beneath the earth's surface from crustal deformation.

I use the method of satellite SAR interferometry (InSAR) for detecting crustal deformation. InSAR is the remote sensing technique to map surface displacements. We can derive the detailed phenomena from detailed information of surface displacements.

JAXA is scheduled to launch a new satellite for land observation, Advanced Land Observation Satellite (ALOS), at 2005 summer. The satellite has L-band SAR sensor. L-band SAR sensor is more suitable to detect surface displacements of vegetated area than C-band. I hope the ALOS to progress geophysical studies of vegetated area, like Japan.
