4.3 quake 28 Jul 9:16 pm (GMT -4)
An earthquake of magnitude 4.3 occurred only 11 minutes ago 49 km southwest of Ovalle, Chile, the European-Mediterranean Seismological Centre (EMSC) reported.
The quake hit at a shallow depth of 14 km beneath the epicenter near Ovalle, Limarí, Coquimbo Region, Chile, in the evening on Thursday, July 28th, 2022, at 9:16 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.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.3 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Ovalle (pop. 77,100) located 49 km from the epicenter, Monte Patria (pop. 13,900) 65 km away, Illapel (pop. 22,800) 96 km away, and Coquimbo (pop. 161,300) 104 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.
