Scientists Create the First Map of Deep Earthquakes Beneath Continents
Scientists once thought Earth’s continental mantle was too weak for earthquakes. A new global map of 459 deep tremors suggests otherwise.

Boomerang Earthquakes Don’t Need Complex Faults
New simulations show earthquakes can reverse direction within seconds on simple, uniform faults, suggesting back-propagating subevents are more common than previously thought.

Liquefaction induced by the 29 March 2025 Mw=7.7 Mandalay earthquake
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. Of all the ground impacts induced by large earthquakes, liquefaction often feels to be the most neglected. The costs can be savage, and the long term implications wide ranging. In this context, […]

Are We Really Seeing More Foreshocks with Enhanced Catalogs?
Different definitions and selection methods can lead to large differences in estimated foreshock rates; however, robust statistical method shows that foreshock rates are similar between standard and enhanced catalog.
