Microscale cavitation as a mechanism for nucleating earthquakes at the base of the seismogenic zone

open access: yesNature Communications, 2017
Earthquakes frequently occur in the brittle-ductile transition near the base of the seismogenic zone. Using shear experiments on calcite faults, here the authors show that microscale cavitation plays a role in controlling the brittle-ductile transition ...
