3.2 quake 17 Jan 3:38 pm (GMT -8)
3.2 quake 17 Jan 3:38 pm (GMT -8)
An earthquake of magnitude 3.2 occurred early afternoon on Sunday 17 January 2021 at 3:38 pm local time near Gresham, Multnomah County, Oregon, USA, as reported by the United States Geological Survey (USGS).
According to preliminary data, the quake was located at a very shallow depth of 1.9 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 3.2 as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Government Camp (pop. 190) located 3 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Odell (pop. 2,300) located 22 miles from the epicenter. In The Dalles (pop. 15,300, 31 miles away), Troutdale (pop. 16,600, 37 miles away), Gresham (pop. 110,600, 38 miles away), Happy Valley (pop. 18,500, 41 miles away), Oregon City (pop. 35,800, 44 miles away), and Portland (pop. 632,300, 50 miles away), the quake was probably not felt.
