Does Sonoma get earthquakes?
Does Sonoma get earthquakes? (KRON) — A preliminary magnitude 3.8 earthquake shook Sonoma County around 2:30 p.m. Sunday, according to the USGS. The quake struck a few miles northwest of The Geysers, a geothermal field that spans around 30 square miles.
What are the signs of a big earthquake coming?
Ground tilting, caused by the buildup of stress in the rocks, may precede a large earthquake, but not always. Water levels in wells fluctuate as water moves into or out of fractures before an earthquake. This is also an uncertain predictor of large earthquakes.
