Manus Plate
The Manus Plate is a 100-km tectonic plate located northeast of New Guinea. The Manus Plate was formed in between the North Bismark Plate and the South Bismark Plate. The Manus Plate currently rotates counter-clockwise in the Melanesia area.

Formation
The Manus Plate formed during the Brunhes chron, making its maximum age 780,000 years old (Lamothe, 2020). The Manus Plate formed in-between and on top of the transform boundaries that were separating the North and South Bismark plates (Lamothe, 2020). The plate was formed of young mid-ocean ridge basalt, along with pieces of older oceanic floor that had broken off of the South Bismarck plate (Lamothe, 2020).

Boundaries and Movement
The northeast and southwest boundaries of the Manus Plate, with the North Bismark and South Bismark plates are both convergent boundaries (Martinez and Taylor, 1996). The plates northwest and southeast borders of the plate, also with North Bismark and South Bismark plates respectively are divergent boundaries (Martinez and Taylor, 1996). The Manus plate currently has a rate of rotation of 51°/ Ma at the spot, -3.04°N, 150.46°E, in the counter-clockwise direction, due to left lateral motion (Lamothe, 2016). This is likely the fastest plate rotation, on Earth at this time (Bird, 2003).
