A magnitude 4.2 earthquake near Esmeraldas, Cantón Esmeraldas, Provincia de Esmeraldas, Ecuador, was reported only 9 minutes ago by the Institute of Geophysics of the National Polytechnic School in Quito (IGEPN), considered the main national agency that monitors seismic activity in this part of the world. The earthquake occurred at a very shallow depth of 8 km beneath the epicenter late at night on Sunday 24 January 2021 at 11:29 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.
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 14 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Muisne (pop. 13,400) located 44 km from the epicenter, Rosa Zarate (pop. 42,100) 62 km away, Valdez (pop. 11,400) 92 km away, and Pedernales (pop. 6,000) 94 km away.
