Recently, I am also interested in how uncertain scientific knowledge could be effectively used in the society. Key Words Crustal deformation / Geodesy / Earthquake / Volcano / Modeling Website Yo Fukushima&＃039;s personal website Research Activities [Understanding earthquake occurrence mechanisms and seismotectonics through InSAR and modeling] A number of studies were done on estimating earthquake fault slip models using InSAR (and GNSS, if available) data. These studies (and many other studies performed by researchers worldwide) found that heterogeneous slip distributions, rough surface ruptures, and branching of slips are quite general. These findings obtained from the high-quality InSAR data that complexity of earthquake rupture is an ubiquitous feature. [Detection of fault creep] By applying InSAR time-series analysis using many SAR images, we can detect small ground displacements of a few mm/year. In the study of the Philippine Fault, our study revealed that the fault creep stressed a locked portion along the fault and eventually led to occurrence of an Mw6.5 earthquake. [Modeling volcanic deformation using InSAR] For my Ph.D. thesis, I worked on the deformation associated with eruptions at Piton de la Fournaise volcano in the Reunion Island. The satellite interferometry (InSAR) data clearly captured the deformation due to dike intrusions. Another work has shown that the 2011 Mw9.0 Tohoku-oki earthquake triggered subsidence around five active volcanoes, which could be associated with weak materials in volcanic regions.
