Simplified diagram of a convergent boundary. A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati ...
Megathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another. The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates.
Three types of plate boundary Convergent boundary Divergent boundary Transform boundary. Tectonic plate interactions are classified into three basic types: [1] Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries.
Comparison of recent and historic earthquakes by energy release. Megathrust earthquakes are large seismic events that take place along convergent plate boundaries, particularly at subduction zones. Examples of subduction zones include the Sumatra and Java trenches, Nankai Trough and Peru–Chile Trench which are frequent sources of these ...
Reverse faults occur in areas where the crust is being shortened such as at a convergent boundary. Reverse faults, particularly those along convergent boundaries, are associated with the most powerful earthquakes (called megathrust earthquakes) including almost all of those of magnitude 8 or more. Megathrust earthquakes are responsible for ...
Induced seismicity, typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on the Earth's crust. [10] Interplate earthquake, an earthquake that occurs at the boundary between tectonic plates. [11] Intraplate earthquake, an earthquake that occurs within the interior of a tectonic plate. [12 ...
Take yourself back to fifth-grade science for a second. You might have learned that earthquakes are caused by the sudden movement of big, underground sheets of rock, called tectonic plates.
Because earthquakes can occur only when a rock is deforming in a brittle fashion, subduction zones can cause large earthquakes. If such a quake causes rapid deformation of the sea floor, there is potential for tsunamis. The largest tsunami ever recorded happened due to a mega-thrust earthquake on December 26, 2004. The earthquake was caused by ...
