An international team of researchers has found evidence of a megathrust earthquake occurring approximately 3,800 years ago off the coast of what is now Chile. In their paper published in the journal Science Advances, the ...
The Cascadia Subduction Zone off the coast of the Pacific Northwest has all the ingredients for making powerful earthquakes—and according to the geological record, the region is due for its next "big one."
