Characterization of nucleation during laboratory earthquakes
Geophysical Research Letters, 2013 We observe the nucleation phase of in‐plane ruptures in the laboratory. We show that the nucleation is composed of two distinct phases, a quasi‐static and an acceleration stage, followed by dynamic propagation. We propose an empirical model which describes the rupture length evolution: The quasi‐static phase is described by an exponential growth while ...

New Physical Implications From Revisiting Foreshock Activity in Southern California
Geophysical Research Letters, 2023 Foreshock analysis promises new insights into the earthquake nucleation process and could potentially improve earthquake forecasting. Well‐performing clustering models like the Epidemic‐Type Aftershock Sequence (ETAS) model assume that foreshocks and ...

Extension of Gutenberg-Richter Distribution to Mw -1.3, No Lower Limit in Sight [PDF]
, 2009 With twelve years of seismic data from TauTona Gold Mine, South Africa, we show that mining-induced earthquakes follow the Gutenberg-Richter relation with no scale break down to the completeness level of the catalog, at moment magnitude MW −1.3.

The sharp turn: Backward rupture branching during the 2023 Mw 7.8 Kahramanmaraş (Türkiye) earthquake
Seismica, 2023 Multiple lines of evidence indicate that the 2023 Mw 7.8 Kahramanmaraş (Türkiye) earthquake started on a splay fault, then branched bilaterally onto the nearby East Anatolian Fault (EAF).

Three-dimensional dynamic rupture simulation with a high-order discontinuous Galerkin method on unstructured tetrahedral meshes [PDF]
, 2012 Accurate and efficient numerical methods to simulate dynamic earthquake rupture and wave propagation in complex media and complex fault geometries are needed to address fundamental questions in earthquake dynamics, to integrate seismic and geodetic data ...

Pervasive Foreshock Activity Across Southern California
Geophysical Research Letters, 2019 Foreshocks have been documented as preceding less than half of all mainshock earthquakes. These observations are difficult to reconcile with laboratory earthquake experiments and theoretical models of earthquake nucleation, which both suggest that ...

A Struggled Rupture Initiation of the Mw 6.1 2009 L’Aquila Earthquake
Geophysical Research Letters, 2023 Understanding under which physical conditions large earthquakes begin, is a key question in Earth science. Laboratory experiments and numerical models have shown that earthquake nucleation has distinct phases: a quasi‐static and an acceleration stage ...
