Significant magnitude 6.0 quake hits 79 km west of Vallenar, Chile late at night

6.0 quake 13 Dec 11:23 pm (GMT -5)
6.0 quake 13 Dec 11:23 pm (GMT -5)
An earthquake of magnitude 6.0 occurred only 12 minutes ago 79 km west of Vallenar, Chile, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near Vallenar, Huasco, Atacama, Chile, late at night on Monday, December 13th, 2021, at 11:23 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.7.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Vallenar (pop. 44,900) located 79 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in La Serena (pop. 154,500) located 148 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.
