A 4.1 magnitude earthquake was reported to have occurred on Wednesday morning in Northern California’s South Sacramento County area, close to Contra Costa, Solano, and San Joaquin Counties.
At 9:29 AM, a first warning was sent out via cell phones throughout Northern California along with the earthquake alarm. The MyShake app, Android operating systems, and messages akin to an Amber Alert are additional ways that the earthquake early warning system can distribute alerts. An app test drill will be held on Thursday at 10:19 AM as part of an international “ShakeOut” day.
Many people in the crowded districts of the Sacramento and San Francisco Bay districts did not feel the tremors of the earthquake. The U.S. Geological Survey claims that the epicenter area saw the strongest shaking, which was just strong enough to vibrate objects.
The initial earthquake’s epicenter was about 10 miles northeast of Oakley, which is in Contra Costa County, and about four miles southeast of Rio Vista, which is in Eastern Solano County.
We’ve had two earthquakes in the previous ten days that occurred in our immediate area and both registered a magnitude of 3.0 or higher.
According to information from the last three years, there are 25 earthquakes with magnitudes between 4.0 and 5.0 on average per year in California and Nevada.
This earthquake occurred 6.7 miles under the surface. Did you hear about this earthquake? If you were, the US Geological Survey (USGS) might use your input to perform a more thorough analysis.
