Japan: Magnitude-6.2 earthquake strikes off east coast of Honshu Dec. 21

Event

A magnitude-6.2 offshore earthquake occurred near the east coast of Honshu, Japan, at around 0323 JST Dec. 21. The epicenter was about 95 km (59 miles) east- northeast of Hachinohe. The tremor occurred at a depth of about 10 km (6 miles), with moderate-to-strong shaking reported near the epicenter and weak-to-light shaking being experienced as far north as Sapporo and as far south as Sendai. There have been no initial reports of damage or casualties; however, minor damage is possible in parts of Aomori and other prefectures near the epicenter. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Aftershocks are likely over the coming days. No tsunami warning has been issued.

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. The event has not prompted any tsunami advisories.

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.
