Current Research

Generation of earthquakes is one of the most dynamic movement of the solid-earth, which extends over a wide spectrum of space-time scales. We aim to develop a comprehensive framework to understand the earthquake generation processes including fault rupture, stress accumulation and the associated deformations of the earth’s surface and interior. We often use an approach interpreting various observed data with fundamental physical elements through modeling aided by computer simulations. Our recent findings address underlying simple mechanisms of apparently complex earthquake phenomena such as triggering of large earthquakes, interactions between earthquakes and volcanoes, geometry of natural faults.
Meanwhile, investigating past earthquakes is important in forecasting future earthquakes. We are also developing new methods applying various numerical analyses and conducting fieldworks to infer past earthquakes from geologic evidence, closely collaborating with geologists and geomorphologists.
