A magnitude 4.4 earthquake was reported 1 hour and 6 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at an intermediate depth of 128 km beneath the epicenter early morning on Friday 20 November 2020 at 2.12 am local time. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
A second report was later issued by the United States Geological Survey (USGS), which listed it as a magnitude 4.4 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Calama (pop. 143,100) located 77 km from the epicenter.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
