Japan: Magnitude-5.2 offshore earthquake occurs near Ryukyu Islands at around 03:08 Sept. 9

Event

A magnitude-5.2 offshore earthquake occurred near the Ryukyu Islands at around 03:08 Sept. 9. The epicenter was approximately 91 km (57 miles) north of Tatsugo. The tremor occurred at a depth of about 5 km (3 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 where shaking occurred.

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.
