Guam: A magnitude-5.6 offshore earthquake occurs in North Pacific Ocean at around 00:58 April 17

A magnitude-5.6 earthquake occurred southeast of Guam at around 00:58 April 17. The epicenter was approximately 112 km (70 miles) east-southeast of Inarajan Village. The tremor occurred at a depth of about 10 km (6 miles), and weak-to-moderate shaking was probably felt throughout much of Guam. There have been no initial reports of damage or casualties as a result of the earthquake; significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. 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.
