The German Research Centre for Geosciences (GFZ) reported a magnitude 4.9 quake in Guatemala near Puerto San José, Municipio de San José, Departamento de Escuintla, only 13 minutes ago. The earthquake hit in the afternoon on Friday 1 January 2021 at 4:11 pm local time at a shallow depth of 10 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 Nicaraguan Institute of Territorial Studies (INETER), which listed it as a magnitude 4.8 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.9.
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 Puerto San José (pop. 18,700) located 101 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include La Gomera (pop. 24,000) located 115 km from the epicenter.
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.
