Moderate 4.8 quake hits near Portoviejo, Cantón Portoviejo, Provincia de Manabi, Ecuador

4.8 quake 17 Aug 12:50 pm (GMT -5)

A magnitude 4.8 earthquake near Portoviejo, Cantón Portoviejo, Provincia de Manabi, Ecuador, was reported only 15 minutes ago by the citizen-seismograph network of RaspberryShake, considered the main national agency that monitors seismic activity in this part of the world. The earthquake occurred at a very shallow depth of 6 km beneath the epicenter around noon on Wednesday, August 17th, 2022, at 12:50 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 4.8 earthquake as well. A third agency, the Institute of Geophysics of the National Polytechnic School in Quito (IGEPN), reported the same quake at magnitude 4.6.
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 Caracas (pop. 37,100) located 57 km from the epicenter, Manta (pop. 183,200) 68 km away, Rocafuerte (pop. 10,300) 78 km away, Montecristi (pop. 18,400) 78 km away, Tosagua (pop. 14,700) 86 km away, Portoviejo (pop. 170,300) 89 km away, and Chone (pop. 44,800) 95 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Calceta (pop. 17,300) located 96 km from the epicenter.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
