The foci basically outline or emanate from the subducting slab (plate). Multiple foci locations can be used to tell the degree of dip/position of the subducting slab. The distribution patterns also give depth at which melting of slab occurs because earthquakes don't emanate from a partially melted slab, so the deepest earthquake may indicate last solid state of slab.

What boundary is it where two plates push together?

An area where two tectonic plates collide is called a boundary. There are three kinds of boundaries. They are convergent, divergent, and transform boundaries.


What type of plate boundary produces strong earthquakes?

Any type of plate boundary can cause an earthquake. That said, areas along convergent, divergent, and transform tectonic plate boundaries are the most likely places for earthquakes to occur.


What type of plate boundary forms earthquake?

earthquakes indicate both convergent,divergent and transform fault plate boundaries


What type of plate boundary with the most occurrences of earthquake?

Transform boundaries are particularly likely to cause earthquakes.


Will a mega earthquake hit Britain?

No. "Mega earthquakes" sometimes known as megathrust earthquakes tend to occur at or near convergent plate boundaries. The UK is not located near to a convergent (or any other type of plate boundary) so will not experience an earthquake of this type.


How the convergent boundaries and the earthquake produce a tsunami?

when the two plate boundaries breaks free, the force causes the water to overflow and create a tsunami. One or both of the plate have to be an oceanic plate. :D


What is the process that causes and earthquake?

Earthquakes are caused by transform faults and when stress overcomes friction. volcanoes are caused by convergent boundaries, the process of convergent boundaries is when two plates come in contact with each other. ex. for volcano is a oceanic plate sub ducts under a continental plate.


Where is the place where two plates collide and one goes on top of the other?

The collisions of plates occur at "convergent boundaries". Convergent boundaries include "subduction zones" (where one goes under the other) and "continental collisions". Please see the related link for more information on the topic.


Are earthquakes characteristics of convergent boundaries?

Earthquakes can occur at convergent boundaries where two tectonic plates collide. This is because the collision causes intense pressure and stress on the rocks, which can lead to sudden release of energy and result in an earthquake. However, it is important to note that earthquakes can also occur at other types of plate boundaries, such as transform boundaries and divergent boundaries.


What is the definition of convergent motion?

Earthquake


Was the valdidvia earthquake on a transform fault?

No. The Valdivia earthquake was on a convergent boundary.


Where does an earthquake normally happen?

Earthquake normally happen at or near the boundaries of tectonic plates. Particularly those where two plates are sliding past each other (a transform boundary) or are colliding (a convergent boundary). They can also occur away from the boundaries of tectonic plates but these tend to be far rarer and of much smaller magnitude.
