A laboratory perspective on accelerating preparatory processes before earthquakes and implications for foreshock detectability

THW Goebel, V Schuster, G Kwiatek, K Pandey… - Nature …, 2024 - nature.com
Dynamic failure in the laboratory is commonly preceded by many foreshocks which
accompany premonitory aseismic slip. Aseismic slip is also thought to govern earthquake …

Fault roughness promotes earthquake‐like aftershock clustering in the lab

THW Goebel, EE Brodsky… - Geophysical Research …, 2023 - Wiley Online Library
Earthquakes rarely occur in isolation but rather as complex sequences of fore, main and
