Ambrym is the site of two active volcanic cones, Benbow and Marum (also spelled Maroum). The center of the island is dominated by a massive 1900-year-old 12 kilometres (7.5 mi) × 8 kilometres (5.0 mi) caldera that hosts multiple craters, and the rest of the caldera floor is ash plain, barren because of natural acid rain. Mt Benbow last erupted in 1913, causing the evacuation of the population to Mele, near Port Vila on Efate.
