Two new studies investigate activity at Hawaii’s Kīlauea leading up to and following the 2018 eruption to better understand the volcano’s plumbing and behavior.
Why does low-frequency energy come from the shallow part of ruptures, and the high frequencies from deep?
Deep-seated earthquakes in subduction zones are related to diamond formation.
Analysis of California earthquakes solidifies links between shaking due to remote earthquakes and increased local earthquake activity that persists for times longer than for regular aftershocks.
For close to 20 years, slow-motion earthquakes have been an enigma. Core samples provide new clues to their origins.
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?
A theoretical study explores why small earthquake sources can produce quasiperiodic sequences of identical events, whereas earthquakes on large faults are intrinsically more variable.
The results of a novel analysis of aftershock size distribution have important implications for more realistically assessing the seismic hazard of earthquake sequences.

Slippage began hours before a landslide-driven tsunami destroyed a village in northwestern Greenland.
