3.8 quake 28 Feb 12:45 am (GMT -8)
A very shallow magnitude 3.8 earthquake was reported after midnight near Salinas, Monterey County, California, USA.
According to the United States Geological Survey, the quake hit on Sunday 28 February 2021 at 12:45 am local time at a very shallow depth of 0.7 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 European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.8 as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include San Simeon (pop. 460) located 21 miles from the epicenter, Greenfield (pop. 17,200) 35 miles away, Soledad (pop. 25,000) 41 miles away, and Paso Robles (pop. 27,200) 46 miles away. In Atascadero (pop. 29,800, 51 miles away), Seaside (pop. 33,000, 57 miles away), Monterey (pop. 28,300, 58 miles away), and Salinas (pop. 157,400, 59 miles away), the quake was probably not felt.
