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.

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.

Potentially deadly and dangerous earthquakes can strike at any time. But can authorities get some early warning from monitoring the hundreds of small quakes that usually go unnoticed?
There are already early warning systems for earthquakes, but advances in seismology provide hope that experts will be able to predict when new ones will occur.
The recent earthquakes in Japan and Ecuador were large, but were they connected?

When two major earthquakes occur within days of each other thousands of kilometres apart, it can look like they’re connected. But are they? Here’s what the science says.
The April 2015 earthquake flattened villages and towns, but more may be to come.

New research shows the earthquake that struck central Nepal in April this year was only a partial rupture of the fault line, meaning another strong quake could be due in future.
