I really doubt it. A lot of the land West of I-5 is drumlins/drumlinoids like Fremont Ridge in Seattle. That's solid ground that has been around since the last glaciation and has come through many earthquakes just fine. On the other hand...If somebody like Brian Atwater said it, that would really get my attention. He's one of the main geologists who tracked down the geological evidence to date the 1700 Earthquake. The force is strong in that one. [1] [1] https://en.wikipedia.org/wiki/Brian_Atwater https://en.wikipedia.org/wiki/Brian_Atwater
