Geodesy Laboratory

I study crustal deformation using GNSS data. I am also interested in other applications of GNSS, such as seismometers, tide gauge and water vapor sensors. I left university after I earned the master degree and was engaged in Geospatial Information Authority of Japan as a technical official. Since I am not a caring person, I ask prospective students to be independent from me. My favorites are playing basketball, touring on a motorcycle, traveling, and eating sweets.

We observe land gravity changes to monitor spatiotemporal mass variations associated with volcanism. For example, we detected the gravity change due to magma movement in the conduit of Asama Volcano using absolute gravimeters (Kazama et al., JGR, 2015).
We also model hydrological gravity changes associated with soil water infiltration and groundwater flow, in order to retrieve solid-earth gravity signals from hydrologically-disturbed gravity data (e.g., Kazama et al., EPS, 2012).
