Mount Benbow
Malampa
Mount Benbow is one of the two active volcanic cones located within the vast caldera of Ambrym Island in Vanuatu. Named after English Admiral John Benbow by Captain Cook, this volcano is part of one of the most active volcanic systems in the New Hebrides arc. The volcano last erupted explosively in 1913, causing significant damage including the destruction of a mission hospital at Dip Point. Ambrym's caldera, measuring approximately 12 kilometers wide, is a result of a massive Plinian eruption around AD 50, which ranks among the largest volcanic explosions in recent geological history. Mount Benbow, along with its neighboring cone Marum, features prominently in the island's rugged volcanic landscape characterized by lava lakes and frequent volcanic activity. The volcano is monitored with advanced gas analyzers to predict eruptions, reflecting its ongoing geological significance. Visitors to Ambrym are drawn to the island's unique volcanic features, tropical jungles, and rich cultural traditions, although accommodations are limited to traditional bungalows rather than hotels.
