Compositional Anomalies Complicate Our Model of Mantle Convection
A new study expands on recent research which suggests that oceanic crust accumulates in the mid-mantle. The new seismological constraints advance our understanding of thermo-chemical planetary evolution.

Atoll Seismometer Detection of Solitary Ocean Waves
Seismic recordings from the South China Sea indicate that subtle, daily tilting of shorelines due to passing internal ocean waves can be measured on land, promising new constraints on ocean dynamics.

Aftershocks and Fiber Optics
Internet cables can be transformed into a string of dense seismic sensors, and this approach has now been shown to be highly useful for quickly monitoring seismicity after major earthquakes.

Earthquake Rates Enhanced by Triggered Creep
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.

Groove is in the Fault
Rock sliding experiments on meter scales show groove patterns which are controlled by normal stress. This may help better understand earthquake source conditions from exhumed faults.

Frequency Dependent Plates
Rocks stretch, break, and flow, depending on how and under which conditions they are loaded. A new formulation to better capture Earth’s rheology is explored in the context of plate thickness.
