Japan: A magnitude-5.7 offshore earthquake occurs off the coast of Fukushima Prefecture at around 00:14 March 15

A magnitude-5.7 earthquake occurred off the coast of Fukushima Prefecture at around 00:14 March 15. The epicenter was about 27 km (17 miles) east-northeast of Iwaki. The tremor occurred at a depth of about 31 km (19 miles), and moderate shaking was probably felt in coastal areas of Fukushima Prefecture, as well as light shaking throughout parts of central and eastern Honshu 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 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.
