Japan: Magnitude-5.0 offshore earthquake strikes west of Okinawa Island at 09:15 April 14

Event

A magnitude-5.0 earthquake occurred west of Okinawa Island at 09:15 April 14. The epicenter was about 137 km (85 miles) west-northwest of Naha. The tremor occurred at a depth of about 10 km (6 miles), and light shaking may have occurred on Okinawa Island. 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 did not prompt 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.
