4.4 quake 12 Aug 3:47 am (GMT -5)
An earthquake of magnitude 4.4 occurred early morning on Friday, August 12th, 2022, at 3:47 am local time near Manta, Cantón Manta, Provincia de Manabi, 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 3 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.4 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Caracas (pop. 37,100) located 77 km from the epicenter, Manta (pop. 183,200) 93 km away, and Montecristi (pop. 18,400) 103 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.
