Small magnitude 3.4 earthquake 22 miles southeast of Hollister, California, United States

3.4 quake 7 Aug 7:38 pm (GMT -7)
3.4 quake 7 Aug 7:38 pm (GMT -7)
An earthquake of magnitude 3.4 occurred early evening on Sunday, August 7th, 2022, at 7:38 pm local time near Hollister, San Benito County, California, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a shallow depth of 7.1 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 3.4 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.4.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Tres Pinos (pop. 480) located 16 miles from the epicenter, Soledad (pop. 25,000) 21 miles away, Hollister (pop. 37,500) 22 miles away, and Greenfield (pop. 17,200) 25 miles away. In Los Banos (pop. 37,500, 31 miles away), Salinas (pop. 157,400, 31 miles away), Gilroy (pop. 53,200, 36 miles away), and Watsonville (pop. 53,600, 41 miles away), the quake was probably not felt.
