The nation's capital sits on shaky ground that jiggles like pudding when earthquakes rattle the East Coast.
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.
When disasters like the Nepal earthquake strike, seemingly out of the blue, one can’t help but feel anguish at the mismatch between the capacity of human memory and the tenacity of denial.
A new study finds that the biggest aftershocks tend to strike at the edge of the original earthquake.
The first good satellite view of Nepal's deadly earthquake could explain why damage in the city was so severe.
The massive earthquake that killed more than 5,000 people in Nepal over the weekend also left dozens of historic buildings in ruins.
Nepal still faces more deadly earthquakes in the near future, even after the magnitude-7.8 temblor that killed more than 3,000 people on Saturday.
Earthquakes threaten roughly half the U.S. population, or more than 143 million people, a new study finds. That number rises when Hawaii, Alaska and Puerto Rico are included.
Geologists have finally found the source of an 1872 earthquake that rattled windows from Washington state to Montana.
Shattered cave formations in the central and eastern United States preserve one of the longest records of powerful earthquakes in these regions.
Earthquakes occur every day, but most people don't notice the small ones. Here's what causes earthquakes.
The 2011 Japan tsunami released thousands of tons of ozone-destroying chemicals and greenhouse gases into the air.
Two new studies explain why some regions of the country are rattling more than others as oil and gas production rises.
Researchers are tuning in to urban seismic noise, the man-made signals from human activity, to view geologic structures and track the rhythms of cities.
A small part of the San Andreas Fault thought to quietly slide without shaking its neighbors may be capable of magnitude-6 earthquakes, a new study finds.
Sports will further science this playoff season, as seismologists monitor the home stadium of the Seattle Seahawks during games in order to test a nascent earthquake early-warning system.
A hydraulic fracturing, or fracking, well in Ohio triggered scores of small earthquakes in March 2014, including one large enough to be felt in nearby towns.
An ancient Chinese civilization that was mysteriously abandoned may have disappeared because of an earthquake that rerouted the city's water flow, new research suggests.
