Tue Mar 24 07:21:12 UTC 2026: # Strong Earthquake Hits Tonga, No Tsunami Threat Issued

The Story: A strong preliminary magnitude 7.6 earthquake struck near Tonga in the South Pacific Ocean on Tuesday, March 24, 2026. While the quake prompted immediate coastal evacuations in Tonga, no wider tsunami warnings were issued. The United States Geological Survey (USGS) reported the earthquake struck at a depth of about 237 km (148 miles), with the epicenter located 153 km (95 miles) west of Neiafu, Tonga’s second-largest town.

Despite the strong shaking reported on the main island of Tongatapu, there were no immediate reports of damage. The Tonga National Disaster Risk Management Office urged residents in low-lying areas to move to higher ground as a precaution. The Pacific Tsunami Warning Center in Hawaii confirmed that there was no tsunami threat due to the earthquake’s depth.

  • Magnitude: Preliminary magnitude 7.6.
  • Location: Near Tonga, South Pacific Ocean; 153 km (95 miles) west of Neiafu.
  • Depth: Approximately 237 km (148 miles).
