Japan: Magnitude-5.7 offshore earthquake occurs near the Ryukyu Islands at around 17:46 Nov. 30

A magnitude-5.7 offshore earthquake occurred in the Ryukyu Islands at around 17:46 Nov. 30. The epicenter was about 193 km (120 miles) southwest of Naha. The tremor occurred at a depth of about 40 km (25 miles), and shaking was probably felt in parts of the southern Ryukyu Islands. 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. 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.
