Inclined fault plane in which upper side is moved upward relative to lower side. If it is a low angle fault plane, called a thrust fault. Here are some major earthquakes that occurred on thrust faults along subduction zone boundaries.

1960 May 22 Chile, 9.5 M earthquake, largest recorded.: ruptured nearly a 1,000 miles of the Southern Chile subduction zone – a mega thrust fault where the Nazca and Pacific tectonic plates are being forced under the South American plate.
1964 March 28 , Prince William Sound, Alaska, magnitude 9.2 earthquake. The earthquake was accompanied by vertical displacement over an area of about 520,000 square kilometers.The rise is estimated to come in two thrusts of about 5 meters each. The main break was a low angle thrust fault--part of the system of faults associated with subduction of the Pacific Plate beneath Alaska.
December 26, 2004 earthquake with an epicentre off the west coast of Sumatra, Indonesia. Magnitude 9.1
All 3 coastal quakes caused big tsunamis as well.

"Other very large megathrust earthquakes occurred in 1868 (Peru, Nazca Plate and South American Plate); 1827 (Colombia, Nazca Plate and South American Plate); 1812 (Venezuela, Caribbean Plate and South American Plate) and 1700 (Cascadia Earthquake, western U.S. and Canada, Juan de Fuca Plate and North American Plate). These are all believed to have been of greater than magnitude 9, but no accurate measurements were available at the time."--http://en.wikipedia.org/wiki/2004_Indian_Ocean_earthquake

The earthquake may occur in normal fault setting though most are associated with thrusting.

Other examples are:
Growth fault, folded mountains in thrust slices/belts, mass-transport complex in shelf area, etc.
