Scientists investigated a magnitude-8.3 earthquake that struck beneath the Sea of Okhotsk, between Russia's Kamchatka Peninsula and Japan, on May 24. The Sea of Okhotsk rests above a subduction ...

Two slow-motion earthquakes took several weeks to travel 20 miles along the fault. Each happened in places where geologic ...

The rugged hills where Cary Grant sought his fortune in the 1939 film "Gunga Din" were also the scene of one of California's biggest earthquakes.

The energy released is determined by how much rock moves and how far it moves. Here’s an explainer for what magnitudes mean, and how that relates to the shaking we feel. This explains why an 8 ...

Fault Slippage: Sudden movements along fault lines release stored energy, causing earthquakes. Isostatic Rebound: Sometimes, after glaciers melt or erosion occurs, the Earth's crust adjusts itself ...

A Look at How Earthquakes Are Measured. Earthquake strength is registered on the moment magnitude scale, which measures how much energy was released when the rocks along a fault moved during the ...

For the first time, the U.S. Geological Survey on Monday will release maps of where manmade earthquake hazards have been identified. The agency has only previously released reports showing the ...

The energy released by the sliding fault needs to be enough to overcome the friction holding rocks in place. Once the earthquake comes up against too much friction, it will stop.

The explosions that devastated Tianjin yesterday were so powerful, they registered as seismic activity by China’s National Earthquake Network. And the ...

The energy released by the earthquake was 32 petajoules, Januka Attanayake told the New York Times, equivalent to nearly 8 million tons of TNT.
