Small Earthquake Near Flagstaff Friday Evening

December 19th, 2021 at 10:09 AM

From the USGS and volcanodiscovery website:

A very shallow magnitude 3.0 earthquake was reported in the evening near Flagstaff, Coconino County, Arizona, USA.
According to the United States Geological Survey, the quake hit on Saturday, December 18th, 2021, at 9:24 pm local time at a very shallow depth of 3.1 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
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 Mountainaire (pop. 1,100, 34 miles away), Flagstaff (pop. 70,300, 36 miles away), Sedona (pop. 10,400, 38 miles away), Sedona (pop. 10,400, 38 miles away), and Village of Oak Creek (Big Park) (pop. 6,100, 40 miles away), the quake was probably not felt.
