stomer
Convergent
At a convergent boundary between oceanic and continental crust where subduction is occurring.
transform boundary
Reventador volcano is located on the South American Plate boundary where the Nazca Plate is subducting beneath it. This type of plate boundary is known as a convergent boundary.
Transform boundary
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.
The earthquake in Haiti was caused by a strike-slip fault along the boundary between the Caribbean Plate and the North American Plate. Strike-slip faults occur when two plates slide past each other horizontally, causing seismic activity.
The Haiti earthquake that occurred in 2010 was a result of a strike-slip boundary where the North American Plate and Caribbean Plate slid past each other horizontally along the Enriquillo-Plantain Garden fault zone.

Converging Plate Boundaries
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.
