The North Portland peninsula, which includes the St. Johns and Cathedral Park neighborhoods, could become isolated from the rest of the city after a major earthquake.

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

A 7.4 magnitude earthquake struck off the southern coasts of Chile and Argentina on Friday, the United States Geological Survey said.

With many of those trapped potentially having sustained serious injuries, and unable to access food or water, operators are now locked in a race against time to get them out before it's too late.

A powerful 7.7-magnitude earthquake has struck Southeast Asia, killing at least 144 people near the epicenter in Myanmar and injuring hundreds more. At least 10 people were killed in neighboring Thailand.

Scientists aren’t worried about eruptions, but they’re deploying seismometers to learn why it’s become more active.

On Wednesday, the council passed a resolution directing city staff to work with PSU and the Halprin Landscape Conservancy to “seek a collaborative solution that combines their respective projects.”

Distance from the epicenter, the kind of soil in your area and even the building you're in can determine how you experience an earthquake.

One of Portland’s iconic bridges needs to be torn down and replaced — and project managers want the public’s input on what the new crossing should look like.

The earthquake early warning system that operates on the west coast got a big upgrade recently. ShakeAlert is now using satellite technology to detect seismic activity.
