Indonesia: Magnitude-5.3 offshore earthquake near southern Sumatra, March 23

A magnitude-5.1 offshore earthquake occurred near southern Sumatra at 20:20 March 23. The epicenter was about 83 km (51 miles) southwest of Pagar Alam. The tremor occurred at a depth of about 60 km (37 miles), and light shaking was probably felt throughout southern and southwestern Sumatra. There have been no initial reports of damage or casualties as a result of the earthquake, and significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. 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.
