BackgroundMount Liamuiga volcano, comprising the NW end of St. Kitts Island, contains a steep-walled, 1-km-wide summit crater, which contained a shallow lake until 1959. Two lava domes are located on the upper western flank, and intrusion of a 3rd dome, Brimstone Hill, on the lower SW flank uplifted a Pleistocene limestone block. Liamuiga volcano (sometimes referred to as Mount Misery) is the youngest of 3 NW-migrating volcanic centers on St. Kitts. Its most recent major eruptions less than 2000 years ago produced pyroclastic flows and mudflows whose deposits underlie populated coastal areas. Reports of possible historical eruptions in 1692 and 1843 are considered uncertain. An earthquake swarm occurred from late 1988 to early 1989, causing small landslides in the summit crater; another earthquake swarm took place in 1999-2000. Active fumaroles are found in the summit crater of Liamuiga.
