A 5.5 magnitude earthquake struck 94 miles from Eureka on Sunday, according to the U.S. Geological Survey.

The earthquake hit off the Northern California coast shortly before noon. The  earthquake occurred 10 miles below the earth’s surface.

Based on low population numbers and the location of the quake, there does not appear to risk of landslides or liquefaction. In addition, a tsunami is not expected, according to the USGS.

Diablo canyon nuclear power plant was upgraded a while back to withstand up to a 6.8 earthquake. I’m not sure if that includes the storage of radioactive waste.


Unfortunately, the Hosgri fault, which runs directly under Diablo, could possibly produce a 7.2 magnitude earthquake.
