Japan: Magnitude-5.0 earthquake occurs in eastern Honshu at around 0935 JST Dec. 30

Event

A magnitude-5.0 earthquake occurred in Ibaraki Prefecture in Kanto Region, eastern Honshu, at around 0935 JST Dec. 30. The epicenter was about 73 km (45 miles) southwest of Iwaki, Fukushima Prefecture. The tremor occurred at a depth of about 83 km (52 miles), and weak-to-light shaking was probably felt throughout eastern Honshu, including Kanto Region and parts of southern Tohoku and eastern Chubu regions. There have been no initial reports of damage or casualties as a result of the earthquake. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Aftershocks are possible 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

Plan accordingly for aftershocks. Consider vacating multistory buildings if operating in affected areas until authorities confirm their structural integrity. Allow additional time for air and road travel, as aftershocks may prompt brief disruptions. Seek updated information on road conditions before driving in hilly areas in the affected region due to potential landslides.
