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

Preparatory slip in laboratory faults: Effects of roughness and load point velocity
Aseismic slip may occur during a long preparatory phase preceding earthquakes, and what
controls it remains poorly understood. In this study, we explored the role of load point …

Fault size–dependent fracture energy explains multiscale seismicity and cascading earthquakes
Earthquakes vary in size over many orders of magnitude, often rupturing in complex
multifault and multievent sequences. Despite the large number of observed earthquakes, the …

How frictional slip evolves
Earthquake-like ruptures break the contacts that form the frictional interface separating
contacting bodies and mediate the onset of frictional motion (stick-slip). The slip (motion) of …

The role of background stress state in fluid‐induced aseismic slip and dynamic rupture on a 3‐m laboratory fault
Fluid injection stimulates seismicity far from active tectonic regions. However, the details of
how fluids modify on‐fault stresses and initiate seismic events remain poorly understood …
