This won't go far, but it's nice to see. When the plants were being built, there was a big burst of seismic and geologic studies for the East. Then, they got in some weird studies which led them to believe they were totally immune to earthquakes, and not a penny was spent on seismic monitoring and such.
Without nuclear money, the seismic monitoring is pathetic in the States. There has never been a seismic reflection study showing the Precambrian megathrusts. So sad.
