There was a 4.0 magnitude earthquake yesterday in Fremont, Northern California. It occurred on the Hayward fault, which runs along in the southeastern shore of San Francisco Bay. The San Andreas fault is on the other side of the Bay near the Pacific Ocean. USGS scientists are saying that residents living on or near the Hayward fault should prepare for a major quake “any day now.” There were 13 smaller aftershocks reported from the same location.
There were a number of minor earthquakes in the L.A. area as well, posted on the KTLA television station website. But, by evening, those stories were replaced by the usual crime news. So I was unable to link to any of them.
I also noticed on the USGS site a large number of minor earthquakes in Oklahoma, so that area is still very active with earthquakes
People wonder if the weather is related to earthquakes. The weather has been muggy and Florida-like in Los Angeles for a few days. An El Nino tropical storm moved in on Saturday and left a fairly heavy rainfall and damage. As reported by KTLA, Interstate 10 was washed out near Desert Center, California.
The weather usually associated with earthquakes, the so-called “shake and bake” conditions are the Santa Ana Desert Winds. These winds come and go between October 1 and late November. Sometimes the Santa Ana wind conditions can last until January. The dry desert winds are coincidental with earthquakes in my opinion. I went through many years of Santa Ana conditions before I experienced an earthquake. Earthquakes take place miles below the surface way below any effects by weather.
