Why does low-frequency energy come from the shallow part of ruptures, and the high frequencies from deep?

Getting to the Bottom of Slow-Motion Earthquakes
For close to 20 years, slow-motion earthquakes have been an enigma. Core samples provide new clues to their origins.

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.

How Do Main Shocks Affect Subsequent Earthquakes?
The results of a novel analysis of aftershock size distribution have important implications for more realistically assessing the seismic hazard of earthquake sequences.

All Earthquakes Are Created Equal
A study of the development of earthquakes shows that the size of the initial rupture does not determine its intensity or range later on.
