A visit to Vanuatu cannot be complete without viewing the erupting Mount Yasur Volcano on the Island of Tanna. It is regarded as the world’s most accessible active volcano. Known for its spectacular persistent strombolian activity consisting of regular small to violent explosions, it has been in more-or-less continuous activity since Captain James Cook observed ash eruptions in 1774. Often referred to as “the lighthouse of the Pacific”, the glow of the volcano apparently led Captain Cook to Tanna during the first European journey to the island. Today the volcano is considered a sacred area by members of the John Frum cargo cult, who believe their deity resides in the heart of the volcano.
