The tremor caused damage to infrastructure, and prompted evacuations and school class suspensions.
The US warning centre has tsunami waves forecast to be less than 0.3 meters above the tide level for the coasts of:
American Samoa
Chuuk FSM
Fiji
French Polynesia
Guam
Hawai’i
Kiribati
Kosrae (FSM)
Marshall islands

The US Tsunami Warning Centre says government agencies responsible for threatened coastal areas should take action to inform and instruct any coastal populations at risk in accordance with their own evaluation, procedures and the level of threat.
Stay out of water
A tsunami advisory remains in effect for the Marianas — the Northern Mariana Islands (CNMI) and Guam. Authorities are warning of hazardous ocean conditions and strong currents along coastlines.
The first tsunami-related sea level fluctuations could reach Guam from 12:45 pm local time, before spreading northward across the Northern Marianas, with estimated arrival times of 12:54pm in Rota, 1:02opm in Tinian and 1:04pm in Saipan.
Officials cautioned that actual arrival times may vary and that the first wave may not be the largest.
Forecast impacts include sea level changes of up to one foot above and below normal tide levels, minor flooding in some beach and harbour areas, and strong and unusual currents in harbours, bays and nearshore waters.
Hazardous conditions could persist for several hours or longer, the advisory said.
Authorities have urged residents and visitors to stay out of the water and away from beaches, harbours and shorelines until the advisory is lifted.
Continue monitoring
Emergency officials stressed that a full-scale evacuation had not been ordered and advised the public to continue monitoring official updates and instructions.
The advisory covers Guam and the Northern Mariana Islands, including Saipan, Tinian and Rota.
Officials said they would continue monitoring the situation and issue additional bulletins as more information becomes available.
