The Nazca plate or Nasca plate, [2] named after the Nazca region of southern Peru, is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. The ongoing subduction , along the Peru–Chile Trench , of the Nazca plate under the South American plate is largely responsible for the Andean orogeny .
All three of these plates are colliding at its intersection point of both the vertical and horizontal lines. [3] Like plates all over the world, each plate moves with its own unique direction and speed. Each plate is moving with a different velocity which can change the outcome and shape of the whole triple junction. [3]
Map showing the location of Nazca Ridge off the west coast of Peru. The Nazca Ridge is a submarine ridge, located on the Nazca plate off the west coast of South America.This plate and ridge are currently subducting under the South American plate at a convergent boundary known as the Peru-Chile Trench at approximately 7.7 cm (3.0 in) per year.

The "war on terror" that began with the September 11 attacks has been claimed by some to be World War III [106] or sometimes World War IV [100] [107] (assuming the Cold War was World War III).

On 1 February 1973, following a reorganization of the Pacific Fleet, the Third Fleet was recommissioned as an active fleet and assumed the duties of the former First Fleet and Pacific Anti-Submarine Warfare Force located at Ford Island, Hawaii. Third Fleet's new duties were to train naval forces for overseas deployment and evaluate state-of-the ...
Forming the Atlantic segment of the boundary between the African and Eurasian plates, the AGFZ is largely dominated by compressional forces between these converging (3.8 to 5.6 mm/a (0.15 to 0.22 in/year)) plates, but it is subject to a dynamic tectonic regime that also involves extension and transform faulting.
The military districts, also known in some English-language publications by their German name as Wehrkreise (singular: Wehrkreis), [1]: 27–40 were administrative territorial units in Nazi Germany before and during World War II. The task of military districts was the organization and the handling of reinforcements and resupplies for local ...
With the rapid fleet buildup of World War II, the Navy ceased naming its carrier air groups with the carrier's name and initially numbered them with the carrier's hull number, and on 25 September 1943 Saratoga Air Group was redesignated Carrier Air Group 3 (CVG-3). After the war, on 15 November 1946 the air group was redesignated in accordance ...
