Repeating caldera collapse events constrain fault friction at the kilometer scale [Earth, Atmospheric, and Planetary Sciences]

Fault friction is central to understanding earthquakes, yet laboratory rock mechanics experiments are restricted to, at most, meter scale. Questions thus remain as to the applicability of measured frictional properties to faulting in situ. In particular, the slip-weakening distance dc strongly influences precursory slip during earthquake nucleation, but scales with...
