Japan: A magnitude-5.7 offshore earthquake occurs south of Honshu Island at around 17:30 June 25

A magnitude-5.7 earthquake occurred in the Pacific Ocean south of Honshu Island at around 17:30 June 25. The epicenter was about 247 km (153 miles) southeast of Kisarazu, Chiba Prefecture. The tremor occurred at a depth of about 41 km (25 miles), and weak-to-light shaking was probably felt throughout parts of Izu Island and Chiba Prefecture. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is unlikely due to the offshore nature of the quake. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light-to-moderate 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.
