Magnitude 3.5 earthquake strikes near Ambler, Northwest Arctic, Alaska, USA

A magnitude 3.5 earthquake near Ambler, Northwest Arctic, Alaska, USA, was reported only 11 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 very shallow depth of miles beneath the epicenter in the morning on Wednesday 5 May 2021 at 10:04 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 3.5 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 Ambler (pop. 270, 47 miles away), the quake was probably not felt.

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
