Physical mechanisms of earthquake nucleation and foreshocks: Cascade triggering, aseismic slip, or fluid flows?

Earthquake Research Advances
Earthquakes 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.

The 8 October 2011 Earthquake at El Hierro (Mw 4.0): Focal Mechanisms of the Mainshock and Its Foreshocks [PDF]

, 2014
We have studied the focal mechanism of an Mw 4.0 earthquake that occurred on 8 October 2011 in the southwest of El Hierro (Canary Islands), the largest shock of the swarm that preceded the submarine eruption of El Hierro 2011–2012.

Large Earthquakes Along the Mendocino Oceanic Transform Fault Hardly Have Any Foreshocks

Geophysical Research Letters
Compared to continental strike‐slip faults, oceanic transform faults (OTFs) are thought to mainly slip aseismically and host significantly more foreshocks triggered by precursory aseismic slip which enhance the mainshocks' short‐term predictability ...

Wei-Jin Dynasty: Talking about seismic activity

地震科学进展
Talking about China’s seismicity research inevitably involves an outstanding female scientist, Mei Shirong. She does not have the title of academician, but is recognized and irreplaceable as an academic leader in the field of earthquake prediction in ...

Partial Ruptures, Cascading Multi‐Fault Ruptures, and Aftershocks in 2D Random Fault Network

Geophysical Research Letters
The Gutenberg‐Richter law for the distribution of earthquake magnitude and the Omori law for the decay of aftershocks are two universal laws in seismicity. Although numerical models have been developed to reproduce these laws, they sometimes produce many

The Distribution of Earthquakes: Recognizing Foreshocks

In this activity, students use online animations of foreshocks in an attempt to decide whether or not they think the earthquakes that occurred on the last day (day 90) of the animations are foreshocks of a large earthquake (mainshock) that will occur on ...

Effect of mainshock selection, earthquake catalog and definition on foreshock rate estimates in Southern California [PDF]

Large earthquakes are sometimes preceded by smaller earthquakes (foreshocks), which may reveal the physical processes leading to large earthquakes. Identifying foreshocks in real-time might alert us to impending large earthquakes, potentially enabling ...

Do plates begin to slip before some large earthquakes?

, 2019
International audienceMany earthquakes are preceded by foreshocks. However, the mechanisms that generate foreshocks and the reason why they occur before some earthquakes and not others are still poorly understood.
