Japan: Magnitude 5.4 Earthquake Strikes Hokkaido

Japan: Magnitude-5.4 earthquake strikes central Hokkaido June 20

A magnitude-5.4 earthquake occurred in central Hokkaido, Japan, at 20:08 June 20. The epicenter was about 31 km (19 miles) northeast of Shimo-Furano. The tremor occurred at a depth of about 158 km (99 miles), and moderate shaking occurred near the epicenter. Moderate-to-light shaking may have taken place in other parts of Hokkaido. There have been no initial reports of damage or casualties. 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 officials do not find any damage. Utility outages cannot be ruled out, particularly near the earthquake's epicenter.
