Details for: Long Island
The broad profile of hexagonal-shaped Long Island, seen here from the east, is dominated by two steep-sided stratovolcanoes, Mount Reaumur in the north (center) and Cerisy Peak in the south. The volcano was named in 1700 by explorer William Dampier, who described it as a "long island, with a high hill at each end." Collapse of the volcanic complex during at least three major explosive eruption about 16,000, 4000, and 300 years ago produced a large 10 x 12.5 km caldera, whose low rim appears at the right.
