Light earthquake of magnitude 4.5 just reported 88 km west of El Aguilar, Argentina4.5 quake 26 Dec 12:18 am (GMT -3)
The German Research Centre for Geosciences (GFZ) reported a magnitude 4.5 quake in Argentina near El Aguilar, Departamento de Humahuaca, Jujuy, only 9 minutes ago. The earthquake hit after midnight on Saturday 26 December 2020 at 12:18 am local time at an intermediate to considerable depth of 220 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.
Our monitoring service identified a second report from INPRES which listed the quake at magnitude 4.6. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.5.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In El Aguilar (pop. 3,700, 88 km away), and Abra Pampa (pop. 9,400, 102 km away), the quake was probably not felt.
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.
