The Community Code Verification Exercise for Simulating Sequences of Earthquakes and Aseismic Slip (SEAS)

Numerical simulations of sequences of earthquakes and aseismic slip (SEAS) have made great progress over past decades to address important questions in earthquake physics. However, significant challenges in SEAS modeling remain in resolving …

Crack Models of Repeating Earthquakes Predict Observed Moment-Recurrence Scaling

Small repeating earthquakes are thought to represent rupture of isolated asperities loaded by surrounding creep. The observed scaling between recurrence interval and seismic moment, $T_r$ ~ $M^{1/ 6}$, contrasts with expectation assuming constant …

Updip and along-strike aftershock migration model driven by afterslip: application to the 2011 Tohoku-Oki aftershock sequence

We present an analytical model based on the idea that afterslip drives seismicity: aftershocks occur when a given level of afterslip is reached in their vicinity. Afterslip is assumed to be governed by a resisting stress that increases as the …

A model for migration of aftershocks driven by afterslip

Aftershocks region have been extensively reported to expand logarithmically with time. The associated migration velocity is typically of the order of several km/decade but can be much larger, especially when observing early aftershock sequences, …

Mapping the rheology of the Central Chile subduction zone with aftershocks

The postseismic deformation following a large ($M_w >$ 7) earthquake is expressed both seismically and aseismically. Recent studies have appealed to a model that suggests that the aseismic slip on the plate interface following the mainshock can be …

A Parallel Code to Calculate Rate-State Seismicity Evolution Induced by Time Dependent, Heterogeneous Coulomb Stress Changes

The estimation of space and time-dependent earthquake probabilities, including aftershock sequences, has received increased attention in recent years, and Operational Earthquake Forecasting systems are currently being implemented in various …

Testing Atmospheric and Tidal Earthquake Triggering at Mt. Hochstaufen, Germany

Seismicity closely related to hydrological impacts has been observed in several locations worldwide, particularly in intraplate areas where tectonic stressing rates are small. The triggering mechanism is usually explained by a poroelastic response of …
