Migration process of very low - frequency events based on a chain - reaction model 1 and its application to the detection of preseismic slip for megathrust earthquakes 2 3
15 In order to reproduce slow earthquakes with short duration such as very low 16 frequency events (VLFs) migrating along the trench direction as swarms, we apply a 17 3-D subduction plate boundary model based on the slowness law of rate-and 18 2 state-dependent friction, introducing close-set numerous small asperities 1 (rate-weakening regions) at a depth of 30 km under high pore pressure cond...

متن کاملEarthquake faulting in subduction zones: insights from fault rocks in accretionary prisms
Subduction earthquakes on plate-boundary megathrusts accommodate most of the global seismic moment release, frequently resulting in devastating damage by ground shaking and tsunamis. As many earthquakes occur in deep-sea regions, the dynamics of earthquake faulting in subduction zones is poorly understood. However, the Integrated Ocean Drilling Program (IODP) Nankai Trough Seismogenic Zone Expe...
متن کاملTremor asperities in the transition zone control evolution of slow earthquakes
[1] Slow earthquakes, characterized by slow slip and associated seismic radiation called non-volcanic tremor, have been observed in major subduction zones worldwide. They constitute an important mode of stress release for the fault’s transition zone, which lies directly downdip of the locked segment, the nucleation zone of large damaging earthquakes. However, the depth of tremor in Cascadia, an...

This paper addresses the influence of boundary conditions and small-scale effect on the free vibration of nano-plates using molecular dynamics (MD) and nonlocal elasticity theory. Based on the MD simulations, Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) is used to obtain fundamental frequencies of single layered graphene sheets (SLGSs) which modeled in this paper as the mo...
