Progress and perspectives in research on crustal stress and earthquakes

Dizhi lixue xuebao
Objective  The crustal stress state is a key physical parameter for understanding lithospheric dynamics, elucidating earthquake preparation mechanisms, and assessing regional seismic hazards.

Interplate seismicity at the CRISP site: the 2002 Osa earthquake sequence [PDF]

, 2011
The Costa Rica Seismogenesis Project (CRISP) is designed to explore the processes involved in the nucleation of large interplate earthquakes in erosional subduction zones.

The mixed mechanisms of large‐earthquake nucleation

Eos, Transactions American Geophysical Union, 2013
Where do big earthquakes come from? That's an important open question in seismology. High‐energy earthquakes often come from faults under high strain, but the mechanism that underlies their onset is still debated.

The existence of a critical length scale in regularised friction

, 2013
We study a regularisation of Coulomb's friction law on the propagation of local slip at an interface between a deformable and a rigid solid. This regularisation, which was proposed based on experimental observations, smooths the effect of a sudden jump ...

Spatiotemporal Variations of In Situ Vp/Vs Ratios During the 2019 Ridgecrest Earthquake Sequence Suggest Fault Zone Condition Changes

Geophysical Research Letters
The 2019 Mw 7.1 Ridgecrest earthquake was the largest event in California over the past 20 years. The earthquake was preceded by a sequence of foreshocks. However, the physical processes leading to the mainshock remain unclear.

Potential for Continental Scientific Drilling to Inform Fault Mechanics and Earthquake Science

Seismica
Our understanding of fault mechanics and earthquake processes remains limited, largely due to minimal direct observations near active faults at seismogenic depths.
