Update Tue, 13 Jul 2021, 19:57Magnitude 3.0 earthquake strikes near Renton, King County, Washington, USA
3.0 quake 13 Jul 12:47 pm (GMT -7)
A magnitude 3.0 earthquake near Renton, King County, Washington, USA, was reported only 10 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a shallow depth of 15 miles beneath the epicenter around noon on Tuesday 13 July 2021 at 12:47 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.0 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Riverton (pop. 6,400) located 2 miles from the epicenter, Burien (pop. 50,500) 2 miles away, Renton (pop. 100,200) 5 miles away, Renton (pop. 100,200) 5 miles away, Seattle (pop. 684,500) 8 miles away, and Kent (pop. 127,000) 9 miles away. In Bellevue (pop. 139,800, 10 miles away), Federal Way (pop. 95,200, 12 miles away), Tacoma (pop. 207,900, 17 miles away), and Olympia (pop. 50,300, 41 miles away), the quake was probably not felt.
