New Zealand's Pacific Medical Association says that people are starting to show signs of post-traumatic stress disorder.
The Hunga Tonga-Hunga Ha'apai volcanic eruption was a one-in-1000-year disaster. The resulting tsunami and ash cloud fallout have devastated the Kingdom. Waves up to 15 metres high destroyed hundreds of homes and wiped out entire villages. Miraculously only three people were killed.
"They thought it was World War III" said Amanaki Misa the Pacific Medical Association team leader currently stationed in Tonga.
