the three types of earthquakes
Earthquakes come in three different forms, depending on the plate movements that occur beneath the earth's surface. One of the types of earthquakes is called a convergent which is when two tectonic plates crash together and one will go over and the other will slip under. The second kind of earthquake is called the divergent, this is when two tectonic plates move away from each other which will then form a crack on the sea floor. The third type of earthquake is the transform fault, this occurs when two different tectonic plate slide past each other.

convergent boundaryIn tectonic plates, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and crash.

divergent boundaryDivergent boundaries in the middle of the ocean contribute to seafloor spreading. As plates made of oceanic crust pull apart, a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a mid-ocean ridge.

Transform FaultA transform fault or transform boundary (also known as a conservative plate boundary) are places where plates slide sideways past each other. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges.
