Informational

Event

A magnitude-5.4 offshore earthquake occurred in the East China Sea near Japan's Ryukyu Islands at around 02:36 JST March 30. The epicenter was about 140 km (87 miles) west-northwest of Naha, Japan. The tremor occurred at a depth of about 10 km (6 miles), and light shaking was probably felt in parts of the Ryukyu Islands. There have been no initial reports of damage or casualties as a result of the earthquake; significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. 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.
