Mexico's National Seismological Service (SSN) reported a magnitude 4.2 quake in Mexico near Ayutla de los Libres, Guerrero, only 15 minutes ago. The earthquake hit around noon on Tuesday 15 June 2021 at 1:03 pm local time at a very shallow depth of 4 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.2 earthquake as well.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In La Fortuna (La Yeguada) (pop. 140) located 12 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Copala (pop. 6,600) located 14 km from the epicenter, Jalapa (pop. 1,700) 24 km away, Cruz Grande (pop. 11,800) 26 km away, Marquelia (pop. 6,600) 27 km away, and Cuautepec (pop. 3,600) 28 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include San Marcos (pop. 13,300) located 49 km from the epicenter, Ayutla de los Libres (pop. 15,400) 52 km away, and Ometepec (pop. 24,100) 72 km away.
