Tongan Earthquake Prompts Tsunami Warning for New Zealand

On May 4, 2006, a powerful earthquake measuring 7.9 on the Richter scale struck near Tonga at 3:26 AM NZST. Located 170 km northeast of Nuku'alofa at a focal depth of 38 km, the quake was felt in Auckland and potentially other regions of New Zealand. The Pacific Tsunami Warning Centre issued a tsunami warning for New Zealand and Fiji shortly after the quake, which was later canceled. Concerns arose about possible tsunamis impacting Fiji and Gisborne, New Zealand, following this seismic event.
