When the Cascadia earthquake hits, it’s going to be bad for pretty much everyone in the Pacific Northwest. One of the more frightening impacts of the “Big One” is that the Oregon coast will literally sink, heightening the effects of the predicted tsunami and permanently altering the coastline. But scientists are now using tiny fossils, called diatoms, to better understand the risks.
Working on the Oregon coast, researchers have found that these diatoms offer clues to how much land will subside and how far a tsunami could wash inland after the next big Cascadia quake.
