The Kumani Bank mud volcano, first identified in 1861, has erupted at least eight times, each event creating short-lived islands. The most powerful eruption, in 1950, produced an island roughly 2,300 feet (700 metres) wide and rising 20 feet (6 metres) above sea level. These islands, however, rarely last beyond a few months or years before sinking back beneath the waves.
