Informational

Event

A magnitude-5.7 earthquake occurred in the Ceram Sea south of West Papua Province at around 18:19 April 28. The epicenter was about 159 km (99 miles) northeast of Tual, Maluku Province. The tremor occurred at a depth of about 10 km (6 miles), and light shaking was probably felt throughout parts of southern and central West Papua, western Central Papua, and eastern and southeastern Maluku provinces. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light-to-moderate 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.
