Earthquake nucleation, rupture and slip on rough laboratory faults [PDF]

, 2018
Fault structural heterogeneity is commonly linked to the nucleation of earthquakes, and once propagating it is used to explain the frictional weakening which drives rupture.

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.

Compositional, mechanical and transport properties of carbonate fault rocks and the seismic cycle in limestone terrains: A case study of surface exposures on the Longmenshan Fault, Sichuan, China

, 2015
Destructive earthquakes are common in tectonically active regions dominated by carbonate cover rocks. The catastrophic Wenchuan earthquake that struck Sichuan, China, also affected a section of carbonate cover terrain.

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.

Numerical simulations of earthquake rupture induced by pressure perturbation

Geodesy and Geodynamics
The subsurface fluid injection can cause pressure increase within faults, leading to earthquake occurrences. However, the factors controlling earthquake rupture due to pressure perturbation remain poorly understood.

Transient Slip Rates as a Key Control on Laboratory-and Natural-Earthquake Nucleation

International audienceThe transition from slow, stable slip to rapid seismic rupture is a key yet incompletely understood phase of earthquake development.

Impact of CO2 geological sequestration on the nucleation of earthquakes

, 2011
Can CO2 storage cause earthquakes? What is the maximum possible earthquake magnitude resulting from CO2 injection? Here, as a theoretical case study we investigate these questions using coupled hydromechanical modeling with multiphase flow and seismological variables for quantifying earthquake magnitude and energy.
