Key Takeaways
A magnitude-7.6 earthquake struck near Tonga in the South Pacific on Tuesday, marking the strongest quake of 2026 thus far. The deep tremor posed no tsunami threat according to authorities.
- Magnitude-7.6 earthquake strikes near Tonga, the strongest of 2026
- Epicenter located about 150km west of Neiafu, Tonga, at a depth of nearly 238km
- No immediate reports of major damage or casualties
- Pacific Tsunami Warning Center confirms no tsunami threat due to earthquake's depth
- Tonga's National Emergency Operation Centre issued a local tsunami alert
The U.S. Geological Survey (USGS) reported that the quake's epicenter was roughly 150 kilometers west of Neiafu, Tonga, and around 370 miles east of Fiji. The tremor occurred at a significant depth of nearly 238 kilometers below the Earth's surface.
According to multiple reports, there were no immediate reports of major damage or casualties. The Pacific Tsunami Warning Center (PTWC) confirmed that no tsunami threat was expected due to the earthquake's considerable depth. In general, tsunami risk is higher when a strong quake happens closer to the ocean floor and causes significant seafloor movement.
The PTWC stated, 'There is no tsunami threat because the earthquake is located too deep inside the earth.' Despite this assurance, Tonga's National Emergency Operation Centre issued a local tsunami alert, with sirens reported in the capital advising people to move away from the coast. There was also no tsunami threat to Australia or New Zealand.
Tuesday's tremor is the biggest anywhere in the world since a magnitude 7.6 earthquake struck off the coast of Japan on Dec. 8, 2025. The largest quake of 2025 was a magnitude-8.8 event near Russia's Kamchatka region, which triggered tsunami warnings across parts of the Pacific.
