A magnitude 4.0 earthquake struck California on Sunday, causing items to fall off of shelves. While not very impactful, I am highlighting this earthquake because it occurred on a lesser known regional fault line. Specifcially, the Bennett Valley fault zone. Today's video will discuss the earthquake sequence that began on November 30th through the analysis and opinion of a geologist.
