During an earthquake scenario with the highest level of subsidence, or land sink, the area at risk of flooding would expand by 116 square miles. Among the areas at risk after a megaquake along the ...

When Washingtonians talk about the possibility of a major earthquake in the Cascadia Subduction Zone, the conversation typically focuses on the immediate impacts: the threat of casualties, building ...

Last week, about 60 miles off the coast near Ferndale, California, the tectonic plates shifted under the Pacific Ocean, sending seismic waves through the ocean floor that radiated onto land and were ...

A 2025 study suggests that when the next "Big One" hits, coastal land could sink by up to 6 feet. That sudden drop could instantly double the number of people, homes, and roads exposed to flooding.
