Penguin Bank is the name given to a now-submerged shield volcano of the Hawaiian Islands. Its coral-capped remains lie immediately west of the island of Molokaʻi, under relatively shallow water (see bathymetric map at the right).


The Penguin Bank volcano is part of the Hawaiian-Emperor seamount chain. It was one of the seven principal Cenozoic Era volcanoes that formerly constituted the prehistoric island of Maui Nui, along with West Molokaʻi, East Molokaʻi, Lānaʻi, West Maui, East Maui, and Kahoʻolawe. The date of the last eruption is unknown.

Boundary area[edit]

Penguin Bank is about 20 miles (32 km) long and 10 miles (16 km) wide and less than 200 feet (61 m) deep.[1] The site coordinates are: NW (21°03′N 157°42′W / 21.050°N 157.700°W / 21.050; -157.700); NE (21°12′N 157°24′W / 21.200°N 157.400°W / 21.200; -157.400); SW (20°54′N 157°36′W / 20.900°N 157.600°W / 20.900; -157.600); and SE (21°03′N 157°21′W / 21.050°N 157.350°W / 21.050; -157.350).[2]


Plans to build wind turbines on Penguin Bank were called off in April 2009.[3]
