Peru: Magnitude-5.3 offshore earthquake occurs in South Pacific Ocean, west of Arequipa Region, at around 21:55 Aug. 13

A magnitude-5.3 offshore earthquake occurred in the South Pacific Ocean at around 21:55 Aug. 13. The epicenter was about 48 km (30 miles) south-southeast of San Juan, Ica Region. The tremor occurred at a depth of about 10 km (6 miles), and light shaking was probably felt in parts of western Arequipa, Ica, and southern Ayacucho regions. There have been no initial reports of damage or casualties; however, significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light aftershocks are likely over the coming days. The event has not prompted any tsunami advisories.

Officials may temporarily shut down transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.
