A deep magnitude 6.1 earthquake struck near Vanuatu, with its epicentre around 188 km below Earth’s surface. Here’s how seismic waves from such a deep quake can still be felt above ground.

Every year, the Earth shakes thousands of times. Most of those tremors go unnoticed, felt only by sensitive instruments buried deep in the ground. Occasionally, though, one of them tears apart cities, ...

The recent string of earthquakes are a reminder that we need to be prepared for “The Big One.” ...

A geophysicist who predicted the Colombia earthquake has warned California is “in the crosshairs” of a huge tremor. Stefan Burns warned the Golden State could be next after a 7.4 magnitude hit El ...

A research group led by Satoshi Ide from the University of Tokyo has demonstrated that classic earthquake generation theory does not hold in areas where the angle at which a tectonic plate dips under ...

A powerful 7.1-magnitude earthquake struck Japan, triggering a tsunami warning. Here's the science behind what happens after a major quake and why aftershocks can be dangerous.

Researchers tested a new technique that uses fiber optic cables to detect earthquakes. It’s twice as precise as what the government currently uses.

Deep beneath the eastern Pacific Ocean about 1,000 miles off the coast of Ecuador, a fault line on the seafloor has been generating magnitude 6 earthquakes with almost clocklike regularity for at ...

A new study reveals that an earthquake early warning system, similar to the USGS ShakeAlert used in California, Oregon, and Washington, could give Alaskan communities precious seconds to prepare ...

Colombia rocked by 7.4 magnitude earthquake—its largest in the past decade This seismic event is of a similar magnitude to ...

The magnitude 7.7 earthquake that struck off Indonesia’s Flores Island early Saturday was generated by an unusual fault system that has produced destructive earthquakes and tsunamis in the past, ...
