A crustal deformation model around the Izu Peninsula considering inland faults and elastic collision

This study models crustal deformation focusing on inland faults and elastic collision around the base of the Izu Peninsula using GNSS(Global Navigation Satellite System) time-series data. First, in order to extract steady deformation, we correct the F3 solution data about antenna replacement from January., 2000 to January., 2010, and remove non-stationary variations using models of earthquakes, volcanic deformation and slow slip events. Next, we set elastic collisional power sources around the base of the Izu Peninsula, locking of plate boundaries, a deep creep of inland faults and a stationary volcanic deformation with a dislocation model and rotational motion of rigid bodies of the Izu micro plate and the Izu arc block (Nishimura, 2011). Then we perform an inverse analysis for the crustal deformation in this region.
