Magnitude 5.2 earthquake strikes near San Antonio, San Antonio Province, Valparaiso, Chile
5.2 quake 18 Apr 11:18 pm (GMT -4)
5.2 quake 18 Apr 11:18 pm (GMT -4)
Just 8 minutes ago, a 5.2-magnitude earthquake struck near San Antonio, San Antonio Province, Valparaiso, Chile. The tremor was recorded late at night on Sunday 18 April 2021 at 11:18 pm local time, at a shallow depth of 10 km below the surface.
The event was filed by the German Research Centre for Geosciences (GFZ), the first seismological agency to report it.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 5.3 earthquake.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Los Navegantes (pop. 230) located 53 km from the epicenter, San Antonio (pop. 85,700) 62 km away, Cartagena (pop. 16,900) 65 km away, Melipilla (pop. 63,100) 90 km away, Valparaiso (pop. 282,400) 110 km away, Viña del Mar (pop. 294,600) 115 km away, and Quilpué (pop. 130,300) 118 km away.
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.
