Most Southern California Mainshocks Follow Foreshocks
New research using a highly complete earthquake catalog shows that 72% of M4+ mainshocks are preceded by foreshocks, implying that foreshock activity is much more prevalent than previously thought.
Shallow Low Frequency Tremors in Japan Trench
A new seafloor seismic network detected low-frequency tremor on the subduction zone interface offshore northern Japan, indicating regions of slow slip in close proximity to shallow megathrust events.
Modeling Tsunamis with Social Media
Video footage gathered from social media is used to reconstruct the timing and likely source(s) of the tsunami generated by the 2018 Palu earthquake.
Imaging an Earthquake Rupture in High Definition
New field measurements using terrestrial laser scanning provide a detailed, centimeter-scale image of surface deformation patterns caused by the Magnitude 6.6 earthquake in Norcia, Italy.
A New Spin on Grain Segregation in Fault Zones
Fine-grained layers in sheared fault gouge may be formed by shear-driven size-segregation in granular materials, rather than by shear localization.
