How fluid viscosity affects earthquake intensity

Fault zones play a key role in shaping the deformation of the Earth's crust. All of these zones contain fluids, which heavily influence how earthquakes propagate. In an article published today in Nature Communications, Chiara ...

Tide gauges capture tremor episodes in cascadian subduction zone

Hourly water level records collected from tide gauges can be used to measure land uplift caused by episodic tremor and slip of slow earthquakes in the Cascadia Subduction Zone, according to a new report in the Bulletin of ...

Mexico's 2017 Tehuantepec quake suggests a new worry

Last September's magnitude 8.2 Tehuantepec earthquake happened deep, rupturing both mantle and crust, on the landward side of major subduction zone in the Pacific Ocean off Mexico's far south coast.

Researchers report new understanding of deep earthquakes

Researchers have known for decades that deep earthquakes—those deeper than 60 kilometers, or about 37 miles below the Earth's surface—radiate seismic energy differently than those that originate closer to the surface. ...

Scientists find pre-earthquake activity in central Alaska

Earth scientists consistently look for a reliable way to forecast earthquakes. New research from University of Alaska Fairbanks Geophysical Institute professor Carl Tape may help in that endeavor, due to a unique set of circumstances.
