Informational

Event

A magnitude-5.9 offshore earthquake occurred in the North Pacific Ocean east of Aomori Prefecture at around 09:14 Aug. 11. The epicenter was about 181 km (112 miles) east of Aomori. The tremor occurred at a depth of about 30 km (19 miles), and light shaking was probably felt throughout Aomori, northeastern Akita, southern Hokkaido, and northern Iwate prefectures. 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 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

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.
