4.3 quake 3 Jul 12:37 am (GMT -5)
A shallow magnitude 4.3 earthquake was reported after midnight near Acapulco de Juarez, Acapulco de Juárez, Guerrero, Mexico.
According to Mexico's National Seismological Service (SSN), the quake hit on Saturday 3 July 2021 at 12:37 am local time at a shallow depth of 14 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.3 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 Calera Dos (pop. 36) located 2 km from the epicenter, Ejido Nuevo (pop. 2,400) 3 km away, Kilometro 30 (pop. 6,300) 3 km away, and Lomas de San Juan (pop. 2,400) 5 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Xaltianguis (pop. 7,000) located 14 km from the epicenter, Tres Palos (pop. 5,000) 17 km away, Acapulco de Juarez (pop. 673,500) 21 km away, Tierra Colorada (pop. 11,500) 32 km away, and Coyuca de Benitez (pop. 13,600) 35 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.
