报告简介：

Pore fluid pressure plays a crucial role in the source processes of earthquakes and episodic slow slip events. In a fluid-infiltrated fault zone with highly compacted granular materials, pore pressure increases due to strong shear heating during rapid slip, leading to a thermal pressurization dynamic weakening effect which promotes further rupture propagation and larger coseismic slip. On the other hand, accelerated slip can also increase fault zone porosity, temporally reduces pore pressure and clamps the fault, hence the dilatancy strengthening effect, before pore pressure re-equilibrates with the ambient level. In this talk, I will discuss numerical simulations that couple pore fluid pressure and fault slip evolution in the framework of rate-state friction law, with applications to earthquakes and aseismic slip events. In particular, strong dilatancy can effectively inhibit seismic slip in frictionally unstable regions, resulting in aseismic slip transients which not only serve as a rupture barrier to earthquakes but may also drive episodic seismic swarms as observed along the East Pacific Rise transform faults. Preliminary results from our recent dynamic rupture model of the 2008 Wenchuan magnitude 7.9 earthquake indicate that 3D fault geometry has a first-order control of the coseismic slip distribution whereas thermal pressurization mainly influences the near-field peak ground motion.
