Long Island is a volcanic island north of Papua New Guinea . The Vitiaz Strait runs between the two islands .
geography
There are two stratovolcanoes on the island: Mount Reaumur and Cerisy Peak . The summit of the volcanic complex collapsed during at least three major eruptions, around 16,000, 4,000, and 300 years ago. These left behind a large caldera that measures 10 × 12.5 km and is now filled by a crater lake, Lake Wisdom . The last eruption was one of the strongest in Papua New Guinea's recent history with an estimated volume of over 11 km³, comparable to the Pinatubo eruption in 1991.
A minor eruption dates back to 1993.
Today the island has five villages with around 1000 inhabitants.
Administratively, the island belongs to the Raicoast District in the southeast of the Madang Province .
history
Long Island was mapped by Abel Tasman in 1643 . He mistakenly believed the island to be part of New Guinea .
During the Second World War , a radar station was set up on the island by the Australian Air Force .
