The quake occurred near the Afghanistan-Pakistan border.
Earthquakes are the result of plate tectonics, or shifting plates in the crust of Earth, and quakes occur when the frictional stress of gliding plate boundaries builds and causes failure at a fault line. In an earthquake, elastic strain energy is released and waves radiate, shaking the ground. Scientists can predict where major temblors might occur in a general sense, but research does not yet allow forecasts for specific locations or accurate predictions of timing. Major earthquakes, some generating tsunamis, have leveled entire cities and affected whole countries. Relatively minor earthquakes can also be induced, or caused by human activity, including extraction of minerals from Earth and the collapse of large buildings.
The central section of the San Andreas Fault usually moves by quietly creeping, but new research suggests it's hosted some serious earthquakes in history.
A mountain-sized chunk of volcanic rock under Japan is changing the way that tectonic plates subduct and may be channeling the direction of earthquakes.
More than 55 earthquakes have struck off the Oregon coast, but the swarm is not likely to trigger any danger to those on land.
Lake Monticello in South Carolina is causing a series of small earthquakes, the third time in its history that the man-made reservoir has created swarms of seismic activity.
A new deep-learning approach to predict earthquake shaking could lead to better warnings of where and when shaking will occur.
An earthquake of approximately magnitude 9 in 1700 in Cascadia could have instead been three or four slightly smaller, but still devastating, quakes.
A swarm of more than 20,000 earthquakes has rattled southern Iceland this week, and geologists suspect a volcanic eruption is on the way.
The earthquake caused the collapse of nearly 20 buildings in the city of Izmir. Search and rescue efforts are underway beneath the rubble.
A big earthquake at Ridgecrest could trigger the Garlock fault, which would in turn trigger the San Andreas.
A powerful magnitude 7.4 earthquake struck the southern coast of Oaxaca, Mexico this morning, killing at least one person.
