Fault zones are often wide, branching networks rather than narrow lines, requiring a shift to 3D models for better earthquake ...

At the Seismological Society of America's Annual Meeting, researchers posed a seemingly simple question: how wide are faults?

Africa has several active seismic zones. In 2016, a group of geologists created the Seismotectonic Map of Africa, highlighting regions based on historical quakes and geological activity.

The US Geological Survey (USGS) detected a 3.8 magnitude earthquake around 8am PT (11am ET) along the Mendocino Fracture Zone, a major geological feature located off the coast of northern California.

Using the newfound data, the researchers imaged the Sierra Nevada through a technique known as receiver function analysis, which uses seismic waves to map Earth’s internal structure. The ...

“Larger earthquakes are unlikely to occur in the original earthquake zone in the near future,” the administration said on its website on Monday. Fan Xiao, a geologist based in ...
