Earthquake

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.

More than 17,000 people in Oregon, Washington and California could almost instantly be living in a floodplain, the researchers found.

Most of us would rather not think about what our lives will be like in the aftermath of the Big One – a magnitude 9.0 rupture of the offshore Cascadia earthquake fault. Yet, it’s worth considering where you’ll go if your house slides off its foundation or your apartment lacks heat, electricity and running water.

The magnitude 7.0 quake, centered about 45 miles southwest of Eureka, set off a tsunami warning that stretched from the Lane/Douglas County line in Oregon south to nearly Santa Cruz, California.

Residents in far Northern California may see a low-flying, fixed-wing plane in the coming weeks. The information it gathers could help communities better prepare for earthquakes.

It’s been close to 30 years since California enacted the bulk of its seismic safety standards, but hospitals continue to ask for more time and flexibility. They argue that many facilities, especially smaller ones, can’t afford the retrofitting or replacement costs.

A 6.4 magnitude quake in late December and a New Year's Day aftershock have left approximately 170 people displaced from their homes.

Is California prepared for The Big One?

After a devastating 6.4 magnitude earthquake on the Northern California coast Tuesday, residents are assessing the damage.

A 6.4 magnitude earthquake rocked parts of Humboldt County in Northern California at 2:30 a.m. Tuesday morning.

New modeling by the University of Washington of the impacts of a major Cascadia earthquake offers a less dire picture of the aftermath of the so-called "Big One" — specifically when it comes to highway bridges.

The quakes were too far away and too shallow to cause a tsunami, according to a geophysicist at the National Earthquake Information Center.
