Frigate leaves for Raoul Island to monitor volcanic activity

Frigate leaves for Raoul Island to monitor volcanic activity

ANZAC frigate Te Mana is on its way to remote Raoul Island to commemorate the death of Kiwi conservation worker Mark Kearney and to monitor volcanic activity.

The trip will also be used to restock the department's base on Raoul Island and to monitor volcanic activity. Little monitoring had been possible since Mr Kearney's death, because DOC had imposed an exclusion zone around the crater lake as a safety precaution, GNS volcano surveillance coordinator Brad Scott said.

He plans to use Te Mana's Seasprite helicopter to make a dawn flight over the island, lowering sample bottles into Green Lake to look at the water chemistry and to take infrared photographs to map the hot spots.

Mr Scott also aims to count and map between 15 and 20 craters formed by the March eruption
