Volcanoes of Vanuatu

Sunday, January 2nd, 2022

A visit to Vanuatu is not complete without a tour of an active volcano. Vanuatu lies directly on top of the Pacific Ring of Fire and has nine active volcanoes, seven on land and two beneath the sea. The most famous and most easily accessible, is Mt Yasur, on Tanna Island bringing thousands of tourists to Tanna Island each year. A Volcano less visited, and away from the crowds can be found on the island of Ambrym in central Vanuatu. The Marum volcano is one of the jewels of the pacific, and is not only one of the most active volcanoes of Vanuatu but also the world. Marum volcano provides a unique trekking opportunity, with a track up to the rim from Port Vatu, for perfect viewing of the bubbling crater.

Ambrym is a large basaltic volcano with a 12-km-wide caldera. Ambrym’s caldera is an impressive moon-like landscape containing an ash plain and containing several active craters and recent lava flows. The volcano is mesmerizing, and the heat can be felt even from the rim, 1200 feet above the fiery pit.

The lava lake of Marum is also a geological conundrum. Most volcanic eruptions are short-term events that quickly dissipate. Only about 1% of eruptions persist for more than a decade; Marum has been active for at least the last 15 years, according to close observers. Understanding where the lava is sourced from – a deep reservoir that may extend laterally across Ambrym – may help clarify how these features form and remain so incredibly active.

Visiting such a beautiful wonder of nature; an active volcano so accessible to Australia, and not experienced by many people, makes Marum volcano on Ambrym Island a must lifetime experience!
