A magnitude 4.7 earthquake near Puerto San José, Municipio de San José, Departamento de Escuintla, Guatemala, was reported only 12 minutes ago by the Nicaraguan Institute of Territorial Studies (INETER), considered the main national agency that monitors seismic activity in this part of the world. The earthquake occurred at a shallow depth of 15 km beneath the epicenter in the evening on Monday 28 December 2020 at 9:54 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 4.7 earthquake as well. Other agencies reporting the same quake include United States Geological Survey (USGS) at magnitude 4.6, and German Research Centre for Geosciences (GFZ) at magnitude 4.8.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Puerto San José (pop. 18,700) located 109 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.
