A magnitude 4.2 earthquake near Puntarenas, Provincia de Puntarenas, Costa Rica, was reported only 25 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a very shallow depth of 6 km beneath the epicenter late at night on Sunday 27 December 2020 at 10:53 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 United States Geological Survey (USGS), which listed it as a magnitude 4.2 earthquake as well.
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 Parrita (pop. 3,700) located 40 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Desamparados (pop. 14,400) located 60 km from the epicenter, Tejar (pop. 22,400) 60 km away, San Rafael Abajo (pop. 27,400) 61 km away, Chacarita (pop. 26,400) 61 km away, Esparza (pop. 15,600) 62 km away, Puntarenas (pop. 35,700) 62 km away, Alajuela (pop. 47,500) 82 km away, and San José (pop. 335,000) 85 km away.
