Moderate magnitude 4.6 earthquake 46 km southwest of Pinotepa Nacional, Mexico

4.6 quake 20 Jun 8:03 pm (GMT -5)
A magnitude 4.6 earthquake near Pinotepa Nacional, Santiago Pinotepa Nacional, Oaxaca, Mexico, was reported only 15 minutes ago by Mexico's National Seismological Service (SSN), considered the main national agency that monitors seismic activity in Mexico. The earthquake occurred at a shallow depth of 10 km beneath the epicenter in the evening on Sunday 20 June 2021 at 8:03 pm local time. 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 European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.6 as well.
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 Callejon de Romulo (pop. 490) located 24 km from the epicenter, Corralero (pop. 1,700) 28 km away, Santo Domingo Armenta (pop. 2,600) 30 km away, El Ciruelo (pop. 2,200) 31 km away, San Nicolas (pop. 3,300) 43 km away, Pinotepa Nacional (pop. 29,600) 46 km away, Cuajinicuilapa (pop. 10,300) 46 km away, Santiago (pop. 10,100) 63 km away, and Ometepec (pop. 24,100) 70 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.

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
