High‐Rate Fluid Injection Reduces the Nucleation Length of Laboratory Earthquakes on Critically Stressed Faults in Granite

Geophysical Research Letters, 2022
We conducted fluid injection experiments on cylindrical low‐permeability granite samples with a critically stressed sawcut fault at local injection rates of 0.2 and 0.8 mL/min and confining pressures of 31 and 61 MPa.

Using the match-and-locate method to characterize foreshocks of the July 2019 MW6.4 Ridgecrest, California earthquakeKey points

Earthquake Science, 2022
The July 2019 MW6.4 Ridgecrest, California earthquake and its distinct foreshocks were well recorded by local and regional stations, providing a great opportunity to characterize its foreshocks and investigate the nucleation mechanisms of the mainshock ...

Earthquake nucleation and fault slip complexity in the lower crust of central Alaska [PDF]

Nature Geoscience, 2018
International audienceEarthquakes start under conditions that are largely unknown. In laboratory analogue experiments and continuum models, earthquakes transition from slow-slipping, growing nucleation to fast-slipping rupture.

Useful predictions ahead of large earthquakes and lessons learned for future progress

Geodesy and Geodynamics, 2020
A significant basis for this article is the outcome of 4 multinational research projects which were carried out in South-West Iceland from 1988–2006, focusing on crustal processes that preceded two magnitude-6.6 earthquakes in June 2000.

Stick-slip nucleation triggering of Wenchuan earthquake

Geodesy and Geodynamics, 2021
The MS8.0 Wenchuan earthquake occurred on May 12th, 2008 on the steeply reverse fault of the Longmen Shan fault zone, Western China. Catastrophic failure and rupture occurred along the listric sliding surface.

Foreshock properties illuminate nucleation processes of slow and fast laboratory earthquakes

Nature Communications, 2023
Understanding the connection between seismic activity and the earthquake nucleation process is a fundamental goal in earthquake seismology with important implications for earthquake early warning systems and forecasting.

Triggering mechanism and brittle-ductile dynamics of active faults in the south-central Saurashtra horst, Gujarat, western India: A geospatial, geological, and geophysical approach

Journal of Asian Earth Sciences: X, 2023
The seismically active Saurashtra horst is located within the intraplate volcanic continental margin of western India. The region is prone to moderate and low-magnitude earthquakes within the depth range of ∼ 3 to ∼ 24 km.

Largest Aftershock Nucleation Driven by Afterslip During the 2014 Iquique Sequence

Geophysical Research Letters, 2023
Various earthquake models predict that aseismic slip modulates the seismic rupture process but actual observations of such seismic‐aseismic interaction are scarce.
