Guam: Magnitude-5.4 offshore earthquake occurs southwest of Guam at around 18:02 May 12
Magnitude-5.4 offshore earthquake occurs near Guam at around 18:02 May 12. No immediate reports of damage or injuries.
Event
A magnitude-5.4 earthquake occurred in the Pacific Ocean southwest of Guam at around 18:02 May 12. The epicenter was about 108 km (67 miles) south-southwest of Merizo Village, Guam. The tremor occurred at a depth of about 10 km (6 miles), and light shaking was probably felt throughout Guam and Rota Island in the 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.
Advice
Out of an abundance of caution, consider vacating multistory buildings where shaking occurred until authorities confirm their structural integrity. Monitor and plan for aftershocks.
