Puerto Rico's January earthquakes came after many foreshocks and have been followed by numerous aftershocks. Scientists are studying these sequences to improve earthquake forecasting.
This unusual earthquake type generates an outsized tsunami.
A tricky kind of earthquake that happens in the soft rock of the ocean floor causes much larger tsunamis than their magnitude would predict. New research pinpoints a way to identify the danger fast.

Post-earthquake aftershocks are often assumed to be less violent, but that's not always the case.

There are three important issues to consider when thinking about quakes: what causes them; how to prepare and plan for them; and, how to move on after a damaging quake.

Engineers know how and where to build to minimize earthquake damage. But laws don't always reflect that wisdom. A new study suggests it's because of a mismatch between risk perceptions and reality.
The quake prompted several buildings to be evacuated in central Darwin.
Because it happened within the Australian Plate rather than at a plate boundary, shockwaves from the quake travelled more efficiently to Darwin than to cities closer to the epicentre.

North Korea is a major military threat to the US and its Asian allies, but exactly how powerful are its nuclear weapons? An earth scientist explains why it's hard to answer this question.

New research shows that injecting wastewater deep underground can cause earthquakes far from the injection site. It also raises questions about which rock layers are the safest injection targets.
Africa’s physical landscape is not a permanent fixture and is being constantly shaped by massive geological forces.

East Africa Rift is undergoing a process that will see the Horn of Africa split from the rest of the continent.
The epicenter of Mexico’s lethal September 2017 earthquake was less than 65 miles outside the nation’s capital.
Not all earthquakes are made equal. A study on the Sept. 2017 quake that killed 300 in Mexico City found that both its location and cause were unusual.
Seismic shockwaves after a meteorite’s collision could affect systems all over the planet.
Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.

According to current forecasts, California has a 93 percent chance of an earthquake with magnitude 7 or greater occurring by 2045. Early warning systems, now in development, could limit casualties and damage.

The Nov. 12 earthquake wasn't centered on any known major faults in the Earth's crust. In its wake, scientists will collect data to add detail to what they know about seismic activity in the area.

Human-induced earthquakes have been reported from every continent except Antarctica. We asked a geologist to investigate whether North Korea's nuclear tests could trigger geological changes.

As global demand for energy and mineral supplies increases worldwide, the number of man‑made earthquakes is expected to rise. That increases the importance of understanding connection between the two.
The city of Juchitan, on Mexico’s southern Pacific coast, was hit particularly hard by the 8.2-magnitude earthquake that shook the region on Sept. 7, 2017.
The Tehuantepec gap in southeastern Mexico, where this month's massive earthquake originated, was long thought to be 'aseismic.' On September 7, scientists learned otherwise.
South Korea’s Meteorological Administration, on the case.
Within hours of North Korea's latest underground nuclear test, Japan and South Korea were both able to independently confirm it had happened. How?
