Map of Earth's principal plates (convergent boundaries shown as blue or mauve lines) The collision between the Eurasian plate and the Indian plate that is forming the Himalayas. [22] [23] The collision between the Australian plate and the Pacific plate that formed the Southern Alps in New Zealand
Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This ...
Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
Tectonic plates are composed of the oceanic lithosphere and the thicker continental lithosphere, each topped by its own kind of crust. Along convergent plate boundaries, the process of subduction carries the edge of one plate down under the other plate and into the mantle. This process reduces the total surface area (crust) of the Earth.

The United States Geological Survey (USGS) placed the earthquake at M w 7.3 with a depth of 57.1 kilometres (35.5 mi). The focal mechanism indicated oblique-normal faulting. Together with the hypocentral depth, this implied faulting within the subducting Australian plate. The USGS proposed two finite fault models: one depicting rupture on a ...
Cartoon of a tectonic collision between two continents. In geology, continental collision is a phenomenon of plate tectonics that occurs at convergent boundaries.Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together.
