Elastic properties of rocks from the seismogenic zone and minimum fault size to nucleate megathrust earthquakes

Progress in Earth and Planetary Science
The elastic properties of rocks in subduction zones are indicators of the stress states and determine the critical length required for earthquake nucleation.

The interactions of fault patterns and stress fields during active faulting in Central North China Block: Insights from numerical simulations.

PLoS ONE, 2019
The interaction of active faults as a factor affecting the mechanisms of large earthquakes has been observed in many places. Most aftershock and clustering earthquake sequences do not recur on the main seismogenic fault but are controlled by fault ...

SEISMOGENIC ZONE OF CAPE SHARTLAY (LAKE BAIKAL): SPECIFIC FEATURES OF STRUCTURE, DISPLACEMENTS AND RUPTURE GROWTH

Геодинамика и тектонофизика
Seismogenic deformations of Cape Shartlay represent a very young fault system on the northwestern coast of Lake Baikal. Their study is providing an important opportunity to measure earthquake magnitudes, to identify areas where earthquakes are more ...

The silent earthquake of 2002 in the Guerrero seismic gap, Mexico (Mw=7.6): Inversion of slip on the plate interface and some implications [PDF]

Geofísica Internacional, 2004
We invert GPS position data to map the slip on the plate interface during an aseismic, slow-slip event, which occurred in 2002 in the Guerrero seismic gap of the Mexican subduction zone, lasted for ~4 months, and was detected by 7 continuous GPS ...

Distinct triggering mechanisms of the 2023 Türkiye earthquake doublet

Communications Earth & Environment
Despite advancements in understanding the rupture processes and surface deformations of the 2023 Türkiye earthquake doublet, their seismogenic mechanisms remain elusive. Here, we employed a joint tomographic method utilizing 215,906 P- and S-wave arrival

Permeability Enhancement by Slow Faulting Under High Pore Fluid Pressure

Geophysical Research Letters
The morphology of fault zones formed by slow faulting is markedly different from that of brittle faulting. In this study, we quantify the three‐dimensional (3D) pore distribution and permeability structures of two rock samples that have been deformed to ...
