Guam: Magnitude-5.0 offshore earthquake occurs south of Guam at around 08:17 ChST July 7

Event

A magnitude-5.0 offshore earthquake occurred south of Guam at around 08:17 ChST July 7. The epicenter was about 106 km (65 miles) south of Merizo. The tremor occurred at a depth of about 10 km (6 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 possible over the coming days.

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.

The event has not prompted any tsunami advisories.

Advice

Plan accordingly for aftershocks. Consider vacating multistory buildings if operating in affected areas until authorities confirm their structural integrity. Allow additional time for air and road travel, as aftershocks may prompt brief disruptions. Seek updated information on road conditions before driving in hilly areas in the affected region due to potential landslides.
