Light magnitude 4.2 earthquake 23 km northeast of Esmeraldas, Ecuador
4.2 quake 27 Jan 2:30 am (GMT -5)
4.2 quake 27 Jan 2:30 am (GMT -5)
The Institute of Geophysics of the National Polytechnic School in Quito (IGEPN) reported a magnitude 4.2 quake in Ecuador near Esmeraldas, Cantón Esmeraldas, Provincia de Esmeraldas, only 9 minutes ago. The earthquake hit early morning on Wednesday 27 January 2021 at 2:30 am local time at a very shallow depth of 5 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 European-Mediterranean Seismological Centre (EMSC), 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 Esmeraldas (pop. 165,200) located 23 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Valdez (pop. 11,400) located 66 km from the epicenter, Muisne (pop. 13,400) 78 km away, San Lorenzo de Esmeraldas (pop. 20,200) 83 km away, and Rosa Zarate (pop. 42,100) 92 km away.
