An earthquake of magnitude 4.8 occurred in the afternoon on Friday 9 July 2021 at 4:07 pm local time near Oaxaca City, Oaxaca de Juárez, Oaxaca, Mexico, as reported by Mexico's National Seismological Service (SSN).
According to preliminary data, the quake was located at a moderately shallow depth of 64 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.
Our monitoring service identified a second report from the United States Geological Survey which listed the quake at magnitude 4.8 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.8.
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 San Pedro Totolapam (pop. 1,600) located 0 km from the epicenter, San Dionisio Ocotepec (pop. 5,500) 17 km away, Tlacolula de Matamoros (pop. 13,800) 36 km away, Ocotlan de Morelos (pop. 15,000) 41 km away, Miahuatlan de Porfirio Diaz (pop. 23,900) 48 km away, San Antonio de la Cal (pop. 20,200) 58 km away, Santa Cruz Xoxocotlan (pop. 67,100) 60 km away, Oaxaca City (pop. 255,000) 62 km away, and Santa Maria Atzompa (pop. 21,800) 69 km away.
