A magnitude 4.3 earthquake near Macas, Cantón Morona, Provincia de Morona-Santiago, Ecuador, was reported only 7 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 5 km beneath the epicenter early afternoon on Thursday, September 2nd, 2021, at 3:34 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.3 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Palora (pop. 6,500) located 51 km from the epicenter, Macas (pop. 23,700) 54 km away, and Sucua (pop. 7,400) 69 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
