Investigations and new insights on earthquake mechanics from fault slip experiments

L Dong, Q Luo - Earth-Science Reviews, 2022 - Elsevier
Earthquakes occur mainly on active faults. Fault slip is closely related to seismicity and is
thus widely discussed in Geosciences, Seismology, and Engineering. Slip experiment is a …
