Long chain of seamounts in the South Pacific Ocean
Not to be confused with the Tasmanian Seamounts.
Tasmantid Seamount Chain
Topographic map of Zealandia that includes the Tasmantid Seamount Chain (unlabelled, above the label Australia) off the east of Australia extending from the Coral Sea southwards into the Tasman Sea.
The Tasmantid Seamount Chain (alternatively Tasmantid Seamounts, Tasman Seamounts, Tasman Seamount Chain,Tasmantide Volcanoes or the Tasmantids)[2] is a 2,000 km (1,200 mi) long chain of seamounts in the South Pacific Ocean. The chain consists of over 16 extinct volcanic peaks, many rising more than 4,000 m (13,000 ft) from the seabed.[3][4][5]
It is one of the two parallel seamount chains alongside the East Coast of Australia; the Lord Howe and Tasmantid seamount chains both run north-south through parts of the Coral Sea and Tasman Sea. These chains have longitudes of approximately 159°E and 156°E respectively.[6]
Like its neighbour, the Tasmantid Seamount Chain has resulted from the Indo-Australian Plate moving northward over a stationary hotspot.[7] It ranges in age from about 56 to 7 million years old.[3]
