Slow Slip By Any Other Name
Earth’s faults slip most catastrophically as earthquakes. The rise of geodesy reveals an array of slower slip events, meaning faults are nearly always active. Are these behaviors really so different?

Earthquake Statistics Vary with Fault Size
A theoretical study explores why small earthquake sources can produce quasiperiodic sequences of identical events, whereas earthquakes on large faults are intrinsically more variable.
