Japan: Magnitude-5.3 offshore earthquake occurs in Philippine Sea Nov. 12

Event

A magnitude-5.3 offshore earthquake occurred in the Philippine Sea near the Ryukyu Islands at around 02:32 Nov. 12. The epicenter was about 169 km (105 miles) southeast of Itoman. The tremor occurred at a depth of about 10 km (6 miles), and weak to-light shaking was probably felt throughout parts of southwest Okinawa. There have been no initial reports of damage or casualties as a result of the earthquake, and 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.

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.
