Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this r

The exact timeline of the recent Nepal flooding disaster is becoming clearer. At 8:37 a.m., instruments recorded what was initially interpreted as an earthquake near Nepal's border with China. Seven m

Erosion rates on parts of the Kaikōura Peninsula more than doubled after the 2016 earthquake, showing major quakes can "rapidly alter" the way coastlines evolve, an Otago researcher says.

Hundreds of previously overlooked seismic events have been detected beneath Antarctica, including 245 near the marine edge of the Thwaites Glacier. Many appear to be glacial earthquakes caused when hu

The Juan de Fuca plate beneath northern Oregon appears to be shallower than previously estimated, potentially making shaking from a future Cascadia megathrust earthquake significantly stronger. Scient

Fracking, the injection of high-pressure fluid to fracture rock and release oil or gas, can trigger earthquakes. While some sites generate small tremors beforehand that may provide an early warning, o

Volcanoes emit smoke. Beneath a volcano lies a huge chamber filled with liquid magma. A series of earthquakes means an eruption is imminent. And if a "supervolcano" like Yellowstone were to awaken, a

Large earthquakes can dramatically reshape mountain landscapes by triggering thousands of landslides and rapidly accelerating erosion. However, the reasons why some mountain regions experience intense
