Cascadia Subduction Zone Earthquake is 314 yrs old


January 26th 1700 was the date of the Cascadia Earthquake. It will come again, with every year that passes increases the odds of it striking.  Are you mental and physical prepared?

The Cascadia subduction zone (also referred to as the Cascadia fault) is a subduction zone, a type of convergent plate boundary that stretches from northern Vancouver Island to northern California. It is a very long sloping fault that separates the Juan de Fuca and North America plates.   Wikipedia

Evidence supporting the date:

Evidence supporting the occurrence of the 1700 earthquake has been gathered into the 2005 book The Orphan Tsunami of 1700, by geologist Brian Atwater and others.

The evidence suggests that it took place at about 21:00 on January 26, 1700 (NS). Although there were no written records in the region at the time, the earthquake’s precise time is nevertheless known from Japanese records of a tsunami that has not been tied to any other Pacific Rim earthquake. The most important clue linking the tsunami in Japan and the earthquake in the Pacific Northwest comes from studies of tree rings (dendrochronology), which show that red cedar trees killed by lowering of coastal forests into the tidal zone by the earthquake have outermost growth rings that formed in 1699, the last growing season before the tsunami. Local Indigenous American oral traditions describing a large quake also exist, although these do not specify the date.[4] There are many areas in the Pacific Northwest with drowned groves of trees that also show evidence of the earthquake.[5]

I wrote a 6 part series based off the Oregon Resilience Report about the mega quake. The Oregon Resilience Report is the best professional analysis of what to expect WHEN the event happens. The report is 200 plus pages long, so I wrote about certain parts I thought people will be interested in.
