Nucleation Mechanism and Rupture Dynamics of Laboratory Earthquakes at Different Loading Rates

Applied Sciences, 2023
The loading rate of tectonic stress is not constant during long-term geotectonic activity and significantly affects the earthquake nucleation and fault rupture process. However, the mechanism underlying the loading rate effect is still unclear.

Sensitivity limits for strain detection of hypothetical remote fluid-induced earthquakes (Mw ≥ 4): a case study in Taiwan

Frontiers in Earth Science, 2023
Capturing and quantifying the timing of remotely triggered earthquakes and understanding the physical processes responsible for this delay represent major challenges in earthquake forecasting.

Nucleation of laboratory earthquakes: quantitative analysis and scalings

Journal of Geophysical Research: Solid Earth, 2023
Abstract In this study we use the precursory acoustic emission (AE) activity during the nucleation of stick‐slip instability as a proxy to investigate foreshock occurrence prior to natural earthquakes. We report on three stick‐slip experiments performed on cylindrical samples of Indian metagabbro under upper ...

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 ...

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.

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.

Estimation of the Nucleation Location and Rupture Extent of the 1850 Xichang, Sichuan, China, Earthquake by Dynamic Rupture Simulations on a Multi‐Segment Stepover Structure

Earth and Space Science, 2023
We simulated the rupture dynamics and ground motion of the 1850 Xichang, China, earthquake on the Zemuhe fault, which consists of the Lijinbao segment, the Dajing segment, the Chechejie segment, and the Songxin segment, with the curved grid finite ...

Temporal variation of shear-wave splitting parameters before and after the 2008 Movri Mountain earthquake in northwest Peloponnese (Greece) [PDF]

, 2013
On June 8, 2008, at 12:25 GMT, a Mw 6.4 earthquake, the Movri Mountain earthquake, occurred in the area of northwest Peloponnese, western Greece. The epicenter was located in the municipality of Movri, 35 km southwest of Patras. For this study, a crustal
