On this date in 1700, a huge earthquake hit the Cascadia Subduction Zone off the coast of the Pacific Northwest.

It had a magnitude 9.0, and affected the coast from Northern California to Southern British Columbia. 

Professor Chris Goldfinger is a marine geologist at Oregon State University.  I asked him how scientists can be so sure about something that happened 310 years ago.
