Magnitude-5.3 offshore earthquake occurs near Guam at around 09:03 ChST Sept. 5. No immediate reports of damage or injuries.
Event
A magnitude-5.3 offshore earthquake occurred near Guam at around 09:03 ChST Sept. 5. The epicenter was about 117 km (73 miles) south-southwest of Merizo Village, Guam. The tremor occurred at a depth of about 9 km (5 miles), and light shaking was probably felt throughout 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.
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.
