The European-Mediterranean Seismological Centre (EMSC) reported a magnitude 5.2 quake in Costa Rica near Corredor, Corredores, Provincia de Puntarenas, only 12 minutes ago. The earthquake hit in the morning on Tuesday 8 December 2020 at 8.20 am local time at a very shallow depth of 7 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 4.9 earthquake.
Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.
Moderate shaking probably occurred in El Coco (pop. 200) located 8 km from the epicenter, La Victoria (pop. 430) 10 km away, Chuchupate (pop. 870) 13 km away, Cuervito Abajo (pop. 810) 14 km away, and Santa Maria (pop. 830) 14 km away.
In Progreso (pop. 2,200) located 15 km from the epicenter, Corredor (pop. 7,100) 18 km away, and Golfito (pop. 6,800) 21 km away, the quake should have been felt as light shaking.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
