Research Abstract

Faults are commonly dominated by clay minerals. To understand frictional response associated with rupture propagation from deep depths, we conducted high-velocity friction experiments on clay-rich fault material. The results show that the frictional strength decreases with displacement due to dehydration of clay minerals. This would enhance rupture propagation toward seafloor and tsunami generation.
