6.1 quake 15 km east of Sullana, Piura, Peru, 30 Jul 12:10 pm (GMT -5)
Peru was shaken near Sullana, Provincia de Sullana, Piura, by an earthquake of magnitude 6.1 only 9 minutes ago, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near Sullana, Provincia de Sullana, Piura, Peru, around noon on Friday 30 July 2021 at 12:10 pm local time. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 6.1 earthquake as well.
Based on the preliminary seismic data, the quake should have been felt by everybody in the area of the epicenter. In those areas, dangerous ground shaking occurred with the potential to inflict moderate to heavy damage to buildings and other infrastructure.
Towns or cities where the quake likely caused strong ground shaking include
Moderate shaking probably occurred in Sullana (pop. 160,800) located 15 km from the epicenter, Querecotillo (pop. 25,400) 16 km away, Marcavelica (pop. 25,600) 18 km away, Tambo Grande (pop. 30,000) 24 km away, Piura (pop. 325,500) 28 km away, San Martin (pop. 130,000) 29 km away, Catacaos (pop. 57,300) 38 km away, and Chulucanas (pop. 68,800) 47 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.
