Today, January 26, 2015, is the 315th anniversary of the last Cascadia Subduction Zone earthquake. At 9 p.m.
By "last" I mean "most recent" -- not final. Another could happen any time...and will -- at magnitude 8 or 9.
The link above to an Oregon Public Broadcasting story explains very well how scientists figured out the date and time so precisely (the estimate of hour thanks to Japanese records of the resulting tsunami).
