Physical Mechanisms of Earthquake Nucleation and Foreshocks: Cascade Triggering, Aseismic Slip, or Fluid Flows?

Earthquake Research Advances
Earthquakes are caused by the rapid rupture of their seismogenic faults. Whether large or small, there is inevitably a certain nucleation process involved before the dynamic rupture.

Crustal P-wave Velocity Structure and Seismogenic Mechanism Constraints in the Kamchatka 2025 MW8.8 Earthquake

CT Lilun yu yingyong yanjiu
An intra-crustal MW8.8 strong earthquake occurred off the eastern coast of Kamchatka, triggering a tsunami and attracting global attention. Some researchers have analyzed the mechanical mechanism of this strong earthquake from the stress field.

Earthquake triggering during preparation for great earthquakes

Geophysical Research Letters, 1984
Seismic quiescence has been proposed as a precursor to many large earthquakes. In this paper we present two cases in which precursory quiescence is interrupted several years prior to great earthquakes by triggered events in the upcoming rupture areas. This triggering results in complex precursory patterns which include seismic quiescence and triggered ...

Evidence for rainfall‐triggered earthquake activity [PDF]

Geophysical Research Letters, 2006
Fluids are known to be of major importance for the earthquake generation because pore pressure variations alter the strength of faults. Thus they can initiate earthquakes if the crust is close enough to its critical state. Based on the observations of the isolated seismicity below the densely monitored Mt.

Advances in the spatiotemporal characteristics and mechanisms of earthquake static and dynamic triggering

地球与行星物理论评
The static and dynamic stress changes induced by earthquakes can further trigger seismic events on surrounding or even remote faults. This phenomenon, known as static and dynamic triggering of earthquakes, has significant implications for earthquake ...

Study on Coulomb Stress Triggering of the April 2015 M7.8 Nepal Earthquake Sequence

International Journal of Geophysics, 2016
In April 2015, a M7.8 earthquake occurred less than one month before a M7.3 earthquake near Kodari, Nepal. The Nepal earthquake sequences also include four larger (M > 6) aftershocks. To reveal the interrelation between the main shock and the aftershocks,

Modeling afterslip and aftershocks following the 1992 Landers earthquake [PDF]

, 2007
One way to probe the rheology of the lithosphere and fault zones is to analyze the temporal evolution of deformation following a large earthquake. In such a case, the lithosphere responds to a known stress change that can be assessed from earthquake slip

Multicycle dynamics of fault systems and static and dynamic triggering of earthquakes [PDF]

, 2007
Dynamic simulations of rupture propagation and multiple earthquake cycles for varying fault geometries are presented. We investigate the role of both dynamic and static stress changes on earthquake triggering.
