Indonesia: Magnitude-5.7 offshore earthquake occurs in Celebes Sea north of Sulawesi Feb. 23

Event

A magnitude-5.7 offshore earthquake occurred in the Celebes Sea north of Sulawesi, Indonesia, at approximately 0332 Feb. 23. The epicenter was approximately 153 km (95 miles) northwest of Gorontalo City. The tremor occurred at a depth of about 40 km (25 miles) and weak-to-light shaking was probably felt throughout northern Sulawesi. There have been no initial reports of damage or casualties. 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

Plan accordingly for aftershocks. Out of an abundance of caution, consider vacating unreinforced multistory buildings if operating in affected areas until authorities confirm their structural integrity. Allow additional time for air and road travel, as aftershocks may prompt brief disruptions. Seek updated information on road conditions before driving in hilly areas in the affected region due to potential landslides.
