Small magnitude 3.4 quake hits 20 miles southwest of McMinnville, Oregon, United States early morning
3.4 quake 4 Dec 6:07 am (GMT -8)
3.4 quake 4 Dec 6:07 am (GMT -8)
A magnitude 3.4 earthquake near McMinnville, Yamhill County, Oregon, USA, was reported only 5 minutes ago by the United States Geological Survey (USGS), considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a moderately shallow depth of 31 miles beneath the epicenter early morning on Friday 4 December 2020 at 6.07 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.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Dallas (pop. 15,300, 19 miles away), McMinnville (pop. 33,900, 20 miles away), Lincoln City (pop. 8,500, 24 miles away), Monmouth (pop. 10,000, 25 miles away), Keizer (pop. 37,900, 29 miles away), Salem (pop. 164,500, 29 miles away), Hayesville (pop. 19,900, 31 miles away), Hillsboro (pop. 102,300, 40 miles away), and Portland (pop. 632,300, 52 miles away), the quake was probably not felt.
