3.4 quake 22 Sep 2:57 am (GMT -7)
An earthquake of magnitude 3.4 occurred only 8 minutes ago 17 miles northwest of Salinas, California, United States, the United States Geological Survey reported.
The quake hit at a very shallow depth of 5.3 miles beneath the epicenter near Salinas, Monterey County, California, USA, early morning on Wednesday, September 22nd, 2021, at 2:57 am local time. 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.4 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Castroville (pop. 6,500) located 9 miles from the epicenter, Marina (pop. 21,200) 10 miles away, Pacific Grove (pop. 15,700) 12 miles away, Watsonville (pop. 53,600) 12 miles away, Seaside (pop. 33,000) 13 miles away, Monterrey (pop. 28,300) 13 miles away, Santa Cruz (pop. 64,200) 14 miles away, and Salinas (pop. 157,400) 17 miles away. In San Jose (pop. 1,026,900, 38 miles away), the quake was probably not felt.
