Problems on Forecasting Great Earthquakes in the Subduction Zones around Japan by Means of Paleoseismology

Temporal variation of large intraplate earthquakes in coupled subduction zones

The focal mechanisms of intraplate earthquakes within subducting lithosphere are frequently used to infer large-scale stress regimes induced by slab-pull, bending or unbending, and lateral segmentation and undulations of the slab . Numerous studies have further postulated that the intraplate activity is influenced by transitory regional stress regimes such as those associated with interplate th...

Dynamic Stress Drop of Recent Earthquakes: Variations within Subduction Zones

Stress drop is a fundamental parameter of earthquakes, but it is difficult to obtain reliable stress drop estimates for most earthquakes. Static stress drop estimates require knowledge of the seismic moment and fault area. Dynamic stress drop estimates are based entirely upon the observed source time functions. Based on analytical formulas that I derive for the crack and slip-pulse rupture mode...

Generation Mechanism of Giant Earthquakes in Subduction Zones with Smaller-Size Interplate Earthquakes During Interseismic Period

Do Trench Sediments Affect Great Earthquake Occurrence in Subduction Zones?

-Seismic energy release is dominated by the underthrusting earthquakes in subduction zones, and this energy release is further concentrated in a few subduction zones. While some subduction zones are characterized by the occurrence of great earthquakes, others are relatively aseismic. This variation in maximum earthquake size between subduction zones is one of the most important features of glob...
