Mount Liamuiga is a 1,156-metre (3,792 ft) stratovolcano which forms the north-western part of the island of Saint Kitts. The peak is the highest point on the island of Saint Kitts, in the federation of Saint Kitts and Nevis, and in the entire British Leeward Islands, as well as one of the tallest peaks in the eastern Caribbean archipelago. The peak is topped by a 1-kilometre (0.6 mi) wide summit crater, which contained a shallow crater lake until 1959. As of 2006, the crater lake had re-formed. The last verified eruptions from the volcano were about 1,800 years ago, while reports of possible eruptions in 1692 and 1843 are considered uncertain.
