Major Quake Triggers Tsunami Warning for NZ's South Island

A tsunami warning is in effect for the west coast of New Zealand's South Island following a significant magnitude 6.3 earthquake detected near Te Anau. The National Emergency Management Agency (NEMA) has advised that land inundation is probable along coastal areas stretching from Milford Sound to Puysegur Point.

Residents in these vulnerable zones have been instructed to evacuate immediately to the nearest high ground, move as far inland as possible, or get out of designated tsunami evacuation zones. The earthquake, with its epicenter 40km north of Te Anau, occurred at a depth of 53km on Thursday evening. Over 13,000 people reported feeling the tremors across the South Island within minutes.

NEMA stresses the urgency for those in affected coastal areas to act without delay and not await further instructions. It has been noted that the initial tsunami wave may not be the most substantial, and continuous tsunami activity is anticipated for several hours until the all-clear is officially given. An Emergency Mobile Alert will be dispatched to relevant areas.

Authorities are cautioning people to stay clear of beaches, shorelines, rivers, and estuaries, and to remain out of the water, including in boats. Listening to local Civil Defence authorities and monitoring official updates are crucial. Return to evacuated areas is prohibited until an official all-clear is announced. Several minor earthquakes have been recorded in the region subsequent to the initial strong event.
