Tracking ancient earthquakes by taking the temperatures of faults

Understanding ancient earthquakes helps researchers estimate the hazards posed by modern earthquakes. Reported in a new study, geologists have come up with a new way to estimate intensity of these old events: take their temperature.

Earthquake modelers unite to compare and improve code

Movement along faults in Earth's crust can be sudden and jarring, as felt during an earthquake, or it can occur more gradually over thousands of years. Any kind of movement along a fault might affect the stresses and other ...

New model may improve Bay Area seismic hazard maps

The Santa Cruz Mountains define the geography of the Bay Area south of San Francisco, protecting the peninsula from the Pacific Ocean's cold marine layer and forming the region's notorious microclimates. The range also represents ...

Ridgecrest shows how earthquakes damage Earth's crust

In July 2019, a series of earthquakes including two major shocks of magnitude 6.4 and 7.1 a day apart struck near Ridgecrest, CA, between Los Angeles and Las Vegas. For local residents, it was a violent interruption to the ...

What fault surface features can tell us about future earthquakes

Earthquakes cannot be forecast like weather, but fault line characteristics, such as structural maturity, can give hints about how a future earthquake may act. Structural maturity is related to the age of the fault, but especially ...
