Preliminary magnitude 7.6 earthquake strikes near Tonga in South Pacific Ocean: USGS

A preliminary magnitude 7.6 earthquake struck near Tonga in the South Pacific Ocean on Tuesday, according to the U.S. Geological Survey. The temblor occurred in a region known for significant seismic activity, situated along the Pacific Ring of Fire where tectonic plates frequently collide. Earthquakes of this magnitude can trigger tsunami warnings and pose serious risk to island nations and coastal communities across the Pacific basin. Tonga lies in one of the world's most tectonically active zones, making it vulnerable to both direct earthquake damage and secondary hazards like tsunamis and aftershocks. Further details on damage, casualties, or tsunami alerts were not immediately available.
