Cascadia’s Fault by Jerry Thompson: America’s Earthquake and Tsunami
The section Cascadia juggles three sea plates and one trench advises us that "Cascadia’s fault line from Cape Mendocino in northern California, through Oregon and Washington, to Vancouver Island off British Columbia in western Canada keeps low geo-historical profiles.
Cascadia’s 19 full margin ruptures of magnitude 9 and 22 partial margin ruptures of magnitude 8 in 10,000 years lead seismologists to rethink California’s upcoming mega-quake. Cascadia’s northern end from mid-Oregon to mid-Vancouver Island and southern end from Cape Mendocino to Newport, Oregon, manifest respectively recurrent intervals of 480 and 240 years. Dr. Kenji Satake of the Geological Survey of Japan and co-authors Kunihiko Shimazaki, Yoshinobi Tsuji, and Kazue Ueda note January 26, 1700, for Cascadia’s last mega-earthquake."
Couldn't it be quite compelling to collect Pacific-Coast native-american legends, lores, myths, stories and tales about the afore-considered Cascadia mega-earthquake of Tues., Jan. 26, 1700?
