Modeling of Earthquake Rupture Process

Current Research

Giant earthquakes very rarely occur and change our society. Meanwhile, countless small earthquakes happen almost all the time in various places in the Earth. Both are fundamentally the same phenomenon: slip movements associated with fracture at underground faults (rupture) and the propagation of seismic waves. While the rupture of large earthquakes occur over a wide area, a large-scale slip occurs but hardly any seismic waves are emitted. This is slow earthquake. Thus, the behavior of earthquakes is diverse. What causes these differences? To fundamentally understand earthquakes, we need to know about the laws governing the accumulation of stress due to plate movement, and the fracture and frictional slip of rocks. Our goal is to explain the complexity and diversity of earthquakes with as simple and realistic physical laws as possible, and to enhance the predictability of their behavior.
