5.5 quake 43 km northwest of Moquegua, Peru, Jul 12, 2022 6:36 pm (GMT -5)
Peru was shaken near Moquegua, Provincia de Mariscal Nieto, Departamento de Moquegua, by an earthquake of magnitude 5.5 only 12 minutes ago, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a moderately shallow depth of 50 km beneath the epicenter near Moquegua, Provincia de Mariscal Nieto, Departamento de Moquegua, Peru, early evening on Tuesday, July 12th, 2022, at 6:36 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 citizen-seismograph network of RaspberryShake which listed the quake at magnitude 5.4. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.7.
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 Pecon (pop. 62) located 18 km from the epicenter, Moquegua (pop. 54,500) 43 km away, and San Antonio (pop. 15,600) 45 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Ciudad Satelite (pop. 76,400) located 65 km from the epicenter, Jacobo Hunter (pop. 46,100) 66 km away, Arequipa (pop. 841,100) 68 km away, Selva Alegre (pop. 72,700) 70 km away, Cono Norte (pop. 47,300) 78 km away, and Ilo (pop. 53,500) 91 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.
