We are investigating the physics of injection-induced seismicity including full poroelastic coupling of stress and pore pressure, and time-dependent earthquake nucleation.

We are working to unify physical-chemical models of erupting volcanoes with resulting deformation, that can be measured with GPS, InSAR, tiltmeters and other instruments.

GPS time series in northeast Japan exhibit nonlinear trends from 1996 to 2011 before the Mw 9.0, 2011 Tohoku-oki earthquake.

One of the most exciting discoveries in recent decades has been the recognition that many subduction zones undergo transient slip events at depths below the locked mega-thrust zone.

GPS position measurements are widely used for studying various geophysical phenomena  including plate movement, strain accumulation, volcanic deformation, post-glacial rebound, subsidence,
