Indonesia: A magnitude-5.4 offshore earthquake occurs west of Aceh and North Sumatra provinces at around 19:05 July 20

A magnitude-5.4 earthquake occurred off the far westcoasts of Aceh and North Sumatra provinces at around 19:05 July 20. The epicenter was about 265 km (165 miles) south-southeast of Sinabang. The tremor occurred at a depth of about 10 km (6 miles), and shaking was probably felt throughout far western Aceh and North Sumatra provinces. 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.
