Moderate magnitude 4.7 earthquake 59 km southwest of Andalgala, Argentina

4.7 quake 29 Jun 9:28 pm (GMT -3)
4.7 quake 29 Jun 9:28 pm (GMT -3)
The German Research Centre for Geosciences (GFZ) reported a magnitude 4.7 quake in Argentina near Andalgala, Departamento de Andalgalá, Catamarca, only 11 minutes ago. The earthquake hit in the evening on Wednesday, June 29th, 2022, at 9:28 pm local time at an intermediate to considerable depth of 166 km. 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 4.7 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.6.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Londres (pop. 2,600) located 54 km from the epicenter, Andalgala (pop. 14,100) 59 km away, Poman (pop. 3,400) 64 km away, Arauco (pop. 13,700) 65 km away, Tinogasta (pop. 14,500) 86 km away, Fiambala (pop. 8,100) 98 km away, San Fernando del Valle de Catamarca (pop. 188,800) 103 km away, and San Fernando del Valle de Catamarca (pop. 188,800) 103 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.
