Zealandia Bank

Stratovolcano · United States · 0m

Zealandia Bank submarine volcano is seen in this NOAA Vents Program bathymetric model from the SW with 2x vertical exaggeration. It consists of two peaks about 1 km apart that rise to near the ocean surface between Guguan and Sarigan Islands. The 2004 survey detected fumarolic activity.

Geological summary

Zealandia Bank consists of two pinnacles about 1 km apart rising from a submerged bank to near the ocean surface between Guguan and Sarigan Islands. One pinnacle reaches more than 1 m above water at low tide. Andesitic rocks were dredged at the southern peak, which showed some evidence of coral growth. Freshly broken pahoehoe basaltic rocks were recovered from 1.7 km depth on the western flank. The age of the most recent eruptive activity is not known, but a NOAA bathymetric survey in 2004 detected fumarolic activity.

From Wikipedia

Zealandia Bank, also known as Farallon de Torres or Piedras de Torres in Spanish, or Papaungan in Chamorro, consists of two rocky pinnacles about 1.5 kilometers apart, in the Northern Mariana Islands in the Pacific Ocean. One reaches a height of approximately 1 meter (3.3 ft) at low tide; the other does not normally broach the surface. They are located 11 nautical miles north-northeast of Sarigan, in between Sarigan and Guguan, but because of their small size, they are not listed in most maps. Zealandia Bank is one of a number of Volcanic Units within the Mariana Arc of Fire National Wildlife Refuge of the Marianas Trench Marine National Monument.
