Illuminating the Pre-, Co-, and Post-Seismic Phases of the 2016 M7.8 Kaikōura Earthquake With 10 Years of Seismicity

The 2016 M7.8 Kaikōura earthquake is one of the most complex earthquakes in recorded history, with significant rupture of at least 21 crustal faults. Using a matched-filter detection routine, precise cross-correlation pick corrections, and accurate …

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 …

The Relationship between Afterslip and Aftershocks: A Study Based on Coulomb-Rate-and-State Models

The spatiotemporal clustering of earthquakes is a feature of medium- and short-term seismicity, indicating that earthquakes interact. However, controversy exists about the physical mechanism behind aftershock triggering: static stress transfer and …
