An earthquake of magnitude 4.5 occurred early morning on Saturday 19 December 2020 at 4:00 am local time near Esmeraldas, Cantón Esmeraldas, Provincia de Esmeraldas, Ecuador, as reported by the Institute of Geophysics of the National Polytechnic School in Quito (IGEPN).
According to preliminary data, the quake was located at a very shallow depth of 5 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.5 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 28 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 69 km from the epicenter, Valdez (pop. 11,400) 89 km away, Rosa Zarate (pop. 42,100) 101 km away, and San Lorenzo de Esmeraldas (pop. 20,200) 106 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
