5.0 quake 4 Jan 6:55 pm (GMT -6)
The Nicaraguan Institute of Territorial Studies (INETER) reported a magnitude 5.0 quake in Panama near Puerto Armuelles, Provincia de Chiriqui, only 11 minutes ago. The earthquake hit early evening on Monday 4 January 2021 at 6:55 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 German Research Centre for Geosciences (GFZ), which listed it as a magnitude 4.8 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.1.
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 Guanabano (pop. 140) located 6 km from the epicenter.
In Altos de San Vicente (pop. 420) located 10 km from the epicenter, Monte Verde (pop. 530) 12 km away, Limones (pop. 320) 12 km away, Puerto Armuelles (pop. 11,700) 13 km away, Agua Buena (pop. 710) 14 km away, San Bartolo Linea (pop. 690) 15 km away, and El Palmar (pop. 4,500) 16 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in David (pop. 82,000) located 61 km from the epicenter.
