Solomon Sea: Magnitude-5.0 offshore earthquake occurs in the Solomon Sea at around 11:54 BST Oct. 2

Event

A magnitude-5.0 offshore earthquake occured in the Solomon Sea at around 11:54 BST Oct. 2. The epicenter was about 117 km (73 miles) south-southwest of Panguna, Papua New Guinea. The tremor occurred at a depth of about 24 km (15 miles), and light shaking was probably felt throughout Bougainville Region in Papua New Guinea as well as Choiseul and Western provinces in the Solomon Islands. 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 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. Consider vacating 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.

Out of an abundance of caution, consider moving away from low-lying coastal areas until local authorities determine that no local tsunami threat exists.
