Tsunamis are less common in the Atlantic Ocean than in the Pacific or the Indian oceans, but they have been observed e.g. after the 1755 Lisbon earthquake. Apart from fault lines, submarine volcanoes such as Kick'em Jenny and landslides are sources of tsunamis in the Atlantic. Tsunamis are not just known from the sea; the Vajont Dam disaster in 1963 claimed 2000 fatalities and was caused by lake-level tsunami and evidence of past tsunamis is recorded from Lake Tahoe.
