A 4.3-magnitude earthquake jolted a lake shoreline Friday, July 11, in Southern California, the U.S. Geological Survey reported. Then dozens of smaller quakes followed. The 6.5-mile-deep quake hit more than 7 miles from Calipatria at 2:55 a.m., according to USGS.

A minor, 3.7-magnitude earthquake struck in Southern California on Thursday. It was followed by a larger, 4.3-magnitude quake nearby a few hours later, according to the United States Geological Survey.

New evidence suggests current estimates about tsunami size and how quickly waves make it to shore may be too high and too fast for some parts of the Northwest coast.

The fault has moved the curbs as much as a handspan, around 18 centimeters, since the time they were installed, up to 60 years ago.

Earthquakes remain one of nature’s most terrifying forces. While we still can’t predict them, science has advanced in identifying where they’re most likely to occur. Our planet’s crust is made of shifting tectonic plates that grind,

If you see smoke from the freeway, don’t worry. The blaze on UC San Diego’s earthquake shake table aims to help make buildings more fire-resistant.

(Reuters) -An earthquake of magnitude 6.7 struck off the coast of Indonesia's Tanimbar Islands region on Monday, the country's geophysics agency said, adding there was no tsunami potential. The quake was at a depth of 98 km (60.89 miles), the agency said.

While most people immediately think of the San Andreas Fault when it comes to potential seismic disasters in the United States, there’s another fault line that has recently been gaining more attention: the New Madrid Seismic Zone.
