An 8.0magnitudeplus earthquake hasn't rumbled beneath the Pacific Northwest since the 1700s. Now, the region is due for the next "big one" and a subsequent tsunami. Coastal Indigenous communities could be severely affected. (Already, the Shoalwater Bay Tribe is constructing a tsunami tower to give their residents a better shot at survival in the face of this kind of natural disaster.)

Clues from the past—paired with modernday science—can help us better understand why this area is at risk and how to best mitigate an earthquake and tsunami's effects.
