In this image, an abseiler can be seen descending towards the eruption of one of the world’s largest lava lakes. More than 1,000 miles off the east coast of Australia lies the country of Vanuatu, an archipelago of over 80 islands spanning almost 5,000 square miles. Within this archipelago is the island of Ambrym and Mount Marum, the crater of which forms the lake.
