Guam: A magnitude-5.1 offshore earthquake occurs south-southwest of Guam at around 20:23 June 13

A magnitude-5.1 earthquake occurred in the western Pacific Ocean south-southwest of Guam at 20:23 June 13. The epicenter was about 86 km (53 miles) south-southwest of Merizo Village, Guam. The tremor occurred at a depth of about 29 km (18 miles), and light shaking was probably felt throughout Guam and Rota Island in far southern Northern Mariana Islands. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light 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.
