Maui, both second youngest and second largest of the Hawaiian Islands, is home to the world's largest dormant volcano, Haleakala, meaning "House of the Sun." Last erupting about 200 years ago, it makes up the eastern end of the island. Maui was formed by volcanic activity from Haleakala on the east and the West Maui Mountains to the west.
