Indonesia: A magnitude-5.5 offshore earthquake occurs in the Indian Ocean northwest of Sumatra Island July 9
A magnitude-5.5 earthquake occurs northwest of Sumatra Island, Indonesia, at 20:09 July 9. No immediate reports of damage or injuries.
Event
A magnitude-5.5 earthquake occurred in the Indian Ocean northwest of Sumatra Island at around 20:09 July 9. The epicenter was about 88 km (54 miles) west-southwest of Banda Aceh. The tremor occurred at a depth of about 88 km (55 miles), and light shaking was probably felt throughout far northwestern Sumatra Island. 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. 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.
Advice
Out of an abundance of caution, consider vacating multistory buildings where shaking occurred until authorities confirm their structural integrity. Monitor and plan for aftershocks.
