Back and forth we go... Same as Washington. According to the video in the article we are over due for a big earthquake. It was stated in the video that a big earthquake every 500 years. -------------------------------------------------- "This is what we call a slow slip type of movement," he said. "The Juan De Fuca Plate is moving underneath us and then all of the sudden, about every 14 months, it stops and it goes in a westerly direction. And as it does that, it creates a lot of tremors. So we are in this slow slip type of movement right now and that's why we're getting a lot of tremors up in Washington, Northern California and then some here in Oregon."50%< [link to www.koin.com (secure)] .

Back and forth we go... Well, Slow Slip tremors are actually a relatively newly discovered phenomenon, and they're also primarily referring to the Cascadia faults, not the more southerly. As for the "small tremors" bit... no. It's been pretty definitively determined that while there is some NOMINAL relief of pressure at fault connections, it's nothing near enough to deter any larger quakes - and that is simple common sense, regardless of research. The M scale is for MAGNITUDE - which means each scale marker is a MAGNITUDE higher than the last. What this means for the theory is that the number of < 5M quakes necessary in a year on any plate to relieve the build up of pressure is SO high that it's essentially impossible. And simple geostudies show that, for example, Juan de Fuca is locked at the pacific plate and has been for a long time, folding in at the subduction - NO volume of small tremors will fix that - well, except the one that actually tips the scale and unlocks the plates. Then, it's a zipper and a HELLUVA ride for me! :D ad ignorantiam - The assumption of a conclusion or fact based primarily on lack of evidence to the contrary. Usually best described by, “absence of evidence is not evidence of absence.” |
