A new, ultra-detailed map shows that 75% of U.S. states are at risk of damaging earthquakes, but some are at far more risk than others.

Satellite images captured striking changes in the coastline of Japan's Noto Peninsula following a massive earthquake on New Year's Day.

A cluster of precariously balanced rocks in California hold secret clues to future earthquakes near Los Angeles.

Researchers have found evidence that aftershocks may continue for centuries after a major earthquake — though the finding is still open for debate.

Fossilized tree analysis finds a single massive earthquake may have rocked what is now Seattle around 1,100 years ago rather than several smaller quakes, and that another equally powerful one could hit the city in the future.

Scientists calculated the diameter of Earth's innermost core using earthquake waves that bounced through the planet 'like ping-pong balls.'

The Feb. 6 earthquake in Turkey and Syria was so deadly because the region sits on a boundary between multiple tectonic plates, while soil and building conditions make strong earthquakes more likely to cause damage.
