3.0 quake 17 Apr 12:35 pm (GMT -7)
An earthquake of magnitude 3.0 occurred only 7 minutes ago 19 miles southeast of Ruth, California, United States, the United States Geological Survey reported.
The quake hit at a moderately shallow depth of 30 miles beneath the epicenter near Ruth, Trinity County, California, USA, around noon on Saturday 17 April 2021 at 12:35 pm 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.0 as well.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Ruth (pop. 200, 19 miles away), Covelo (pop. 1,300, 24 miles away), Red Bluff (pop. 14,100, 43 miles away), and Anderson (pop. 10,200, 46 miles away), the quake was probably not felt.
