Southern California Edison states the station was “built to withstand a 7.0 magnitude earthquake directly under the plant”. Additionally, there is a 25-foot tsunami wall to protect the plant from a rogue wave that could be potentially generated by the active fault 5 miles offshore. The closest tectonic fault line is the Christianitos fault, which is considered inactive or “dead”.

The wall can be seen in the enlarged photo below:

Thanks. Withstand 7.0 is good. The wall is good, but it looks like they carved out a spot to build it down in the flood zone, instead of building above it. That seems odd.
