We had a swarm of minor earthquakes in Southern California this past weekend ranging from Inglewood to Victorville and from Ventura County to Orange County. I should note that I didn’t feel any earthquakes where I live.
According to KTLA, a local LA news station, some were speculating that earthquakes in and around the Baldwin Hills area of Los Angeles were caused by fracking, as the area has a long history of oil drilling. But Dr. Lucy Jones of the USGS (a familiar figure to long time L.A. residents) said that recent earthquakes there occurred way below the oil fields.
The I-35 area in Oklahoma also apparently experienced another swarm of earthquakes as well. It is probably too soon to tell whether this will become a major fault zone such as the San Andreas, but it does appear that earthquakes are becoming a way of life there. There seems to be a world wide upsurge in earthquakes.
