A moderately shallow magnitude 4.6 earthquake was reported in the evening near Portoviejo, Provincia de Manabi, Ecuador.
According to the United States Geological Survey, the quake hit on Thursday, September 18th, 2025, at 8:49 pm local time at a moderately shallow depth of 35. km. 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 Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 4.6 earthquake as well. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.6, the Institute of Geophysics of the National Polytechnic School in Quito (IGEPN) at magnitude 4.7, The Colombian Geological Service (SGC) at magnitude 4.4, and the citizen-seismograph network of RaspberryShake at magnitude 4.2.
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 Jipijapa (pop. 35,900) located 27 km from the epicenter, Montecristi (pop. 18,400) 30 km away, Manta (pop. 264,300) 37 km away, Sucre (pop. 15,300) 44 km away, and Portoviejo
