4.8 quake 9 Dec 6:14 pm (GMT -5)
An earthquake of magnitude 4.8 occurred only 15 minutes ago 12 km northeast of San Gil, Colombia, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at an intermediate to considerable depth of 173 km beneath the epicenter near San Gil, Santander, Colombia, early evening on Thursday, December 9th, 2021, at 6:14 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.8 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Curiti (pop. 3,400) located 7 km from the epicenter, San Gil (pop. 33,600) 12 km away, Socorro (pop. 17,800) 28 km away, Piedecuesta (pop. 86,400) 37 km away, Malaga (pop. 18,700) 41 km away, Floridablanca (pop. 252,300) 45 km away, Giron (pop. 108,500) 46 km away, Bucaramanga (pop. 571,800) 52 km away, and Barrancabermeja (pop. 191,400) 95 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
