Significant 5.2 quake hits near Sonsonate, Departamento de Sonsonate, El Salvador
5.2 quake 12 May 12:17 am (GMT -6)
5.2 quake 12 May 12:17 am (GMT -6)
A magnitude 5.2 earthquake near Sonsonate, Departamento de Sonsonate, El Salvador, was reported only 13 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at an intermediate depth of 79 km beneath the epicenter after midnight on Wednesday 12 May 2021 at 12:17 am 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 5.1 earthquake.
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 Acajutla (pop. 22,800) located 58 km from the epicenter, Sonsonate (pop. 59,500) 76 km away, Sonzacate (pop. 15,400) 78 km away, Izalco (pop. 19,200) 82 km away, Ahuachapan (pop. 34,100) 86 km away, Santa Ana (pop. 176,700) 110 km away, Santa Tecla (pop. 124,700) 113 km away, San Salvador (pop. 526,000) 122 km away, Mexicanos (pop. 160,300) 124 km away, and Soyapango (pop. 329,700) 128 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.
