A powerful earthquake struck the Pacific Ocean early Monday morning, prompting tsunami alerts for areas closest to the epicenter. The USGS reported a magnitude 7.1 quake about 56 miles southeast of Pangai, Tonga, at a depth of 6 miles. Shaking was felt in nearby towns, including Pangai and Nukualofa.
Tsunami waves were observed along several coastlines, including Niue, Tonga, American Samoa, and Fiji, with wave heights ranging from 1-3 feet possible. However, officials confirmed the tsunami threat had passed about an hour after initial alerts, though people near coastal areas are advised to remain vigilant for minor sea-level fluctuations in the coming hours.
