Earthquake Nucleation Along Faults With Heterogeneous Weakening Rate [PDF]
Geophysical Research Letters, 2021 The transition from quasistatic slip growth to dynamic rupture propagation constitutes one possible scenario to describe earthquake nucleation. If this transition is rather well understood for homogeneous faults, how the friction properties of multiscale

Earthquake nucleation in the lower crust by local stress amplification [PDF]
Nature Communications, 2020 This study investigates deep intracontinental earthquakes. Based on field data from exhumed lower crustal pseudotachylytes and mylonites from Lofoten, northern Norway, the authors describe a novel model of earthquake nucleation in the lower crust as a ...

Earthquake Research AdvancesEarthquakes are caused by the rapid slip along seismogenic faults. Whether large or small, there is inevitably a certain nucleation process involved before the dynamic rupture.

On the Mechanism of Laboratory Earthquake Nucleation Highlighted by Acoustic Emission. [PDF]
Sci Rep, 2020 Dynamics of granular media is the key to understanding behavior of many natural systems. In this work we concentrate on studying regularities of deformation of a gouge-filled fault.

Different earthquake nucleation conditions revealed by stress drop and b-value mapping in the northern Chilean subduction zone. [PDF]
Sci RepStress drop is an earthquake property indicative for the characteristic relation of slip to fault dimension. It is furthermore affected by fault strength, fault topography, the presence of fluids, rupture size, slip, and velocity.

Traces Of Laboratory Earthquake Nucleation In The Spectrum Of Ambient Noise. [PDF]
Sci Rep, 2018 The short-term forecast of earthquakes associated with fault rupture is a challenge in seismology and rock mechanics. The evolution of mechanical characteristics of a local fault segment may be encoded in the ambient noise, thus, converting the ambient ...
