Yup. He’s accurate. I’ve been watching Dutchsinse for awhile and he’s good. He believes that there’s probably a volcano erupting underwater in the Cascadia subduction zone that the USGS is not reporting in order to avoid public concern. He believes such an eruption is not a direct concern, but says that accurate information about seismic activity at that location would help anticipate larger “releases of pressure” (EQ) in the subduction zone and all down the coast of CA.
He believes that down the west coast where the fault lines lie, many small tremors are occurring in clusters. He has said that we wouldn’t expect a significant EQ as long as the movement small tremors continue on land (called slow slipping). He believes that when a location midway between two areas experiencing tremors becomes “too still” the likelihood of a significant earthquake increases the longer the midpoint is “still.”
If you watch a few of his full broadcasts that come out in the evenings, you can learn his methodology. He reviews his earthquake forecasts for accuracy and discusses current activity and makes new forecasts.
His creed is “Don’t be scared. Be prepared,” and he periodically reviews earthquake preparedness tips. Even if you don’t watch him, it’s always a good time to check the earthquake preparedness kit and talk to the family. :)
