Playing with volcanoes

People are always away from the volcano when they operate, but 6 New Zealand men are betting their lives to admire the red lava of a giant volcano in the Pacific.

6 men built camps near the Marum volcano on Ambrym island in the eastern Pacific island of Vanuatu in early October.

Johno Smith and Drew Bristow put wires on the stone to prepare for climbing down the crater.

Two other people check the strength of the wire.

Team leader is volcanic expert Geoff Mackley and he is responsible for filming.

Mackley has done this for 13 years and has never had a serious problem.

Drew Bristow, a member of the group, climbs up after watching the lava.
