Moderate magnitude 4.9 quake hits 9 km southeast of Tacna, Peru early morning 4.9 quake 8.8 km southeast of Tacna, Peru, May 18, 2022 6:27 am (GMT -5)
An earthquake of magnitude 4.9 occurred only 9 minutes ago 9 km southeast of Tacna, Peru, the citizen-seismograph network of RaspberryShake reported.
The quake hit at an intermediate depth of 130 km beneath the epicenter near Tacna, Provincia de Tacna, Peru, early morning on Wednesday, May 18th, 2022, at 6:27 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 4.8 earthquake. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 4.5.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Sobraya (pop. 700) located 7 km from the epicenter, Tacna (pop. 280,100) 9 km away, Chipispaya (pop. 1,900) 63 km away, Tarata (pop. 3,100) 67 km away, Totoral (pop. 2,000) 75 km away, Ilabaya (pop. 9,500) 79 km away, Quilahuani (pop. 3,200) 83 km away, Chuquitira (pop. 4,200) 87 km away, and Candarave (pop. 3,400) 89 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.
