      This shocking statement is surely true within a geologic time frame of thousands of years because the evidence is strong that the Cascadia Subduction Zone will generate great earthquakes every few centuries. The last one was in A.D. 1700, three hundred years ago. The recognition that the Pacific Northwest is subject to large earthquakes was slow in coming, but since the 1980s, it has been accepted by the scientific community as a major paradigm change.
