Indonesia: Magnitude-5.4 offshore earthquake occurs near Nias at around 18:16 June 5

A magnitude-5.4 offshore earthquake occurred near Nias Island at around 18:16 on June 5. The epicenter was about 123 km (76 miles) southwest of Padang Sidempuan. The tremor occurred at a depth of about 47 km (29 miles), and strong to moderate shaking was probably felt near the epicenter on Nias Island, with light shaking likely across Sumatra. There have been no initial reports of damage or casualties as a result of the earthquake. 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.
