January 26th, at 9:00pm marks the 313th anniversary of the great Cascadia Earthquake of 1700. A 620 mile stretch of coastline from Northern California, all of Oregon and Washington to Southern British Columbia was involved. Multiple tsunami waves impacted our coastline about 30 minutes later reaching heights of 20-30 feet destroying everything in their paths for great distances. Tsunami waves even impacted Japan some 10-15 hours later with 6-10 foot waves destroying many villages and claiming lives without notice to the citizens.
