The earthquake occurred at a convergent boundary between the Nazca and South American plates which are converging at a rate of approximately 80mm / year. The dense oceanic crust of the Nazca plate is being forced under or subducted beneath the less dense continental crust of the South American Plate.
At a convergent boundary between oceanic and continental crust where subduction is occurring.
No, the 2011 Japan earthquake was a megathrust earthquake, specifically a subduction zone earthquake. It occurred along the boundary between the Pacific Plate and the North American Plate, where the Pacific Plate is subducting beneath the North American Plate.
The two earthquakes occurred due to differing types of fault movement (thrust faulting in the Chilean quake vs strike slip faulting in the Haitian quake) and at two differing types of plate boundaries. In the case of the Chilean earthquake, this was at a convergent boundary where the Nazca oceanic plate is being subducted under the continental South American plate as opposed to the Haitian earthquake which occurred at a transform boundary between the Caribbean and North American plates which are both moving east but at differing speeds. The Haitian earthquake was also of lower magnitude (magnitude 7.0) than the Chilean earthquake (magnitude 8.8) however it caused more damage and led to a much larger number of injuries and fatalities due to the poor construction techniques used in Haiti.

The 1755 Lisbon earthquake occurred at the boundary between the African Plate and the Eurasian Plate. This boundary is known as a convergent boundary, where the two plates are colliding, causing seismic activity.
The L'Aquila earthquake in 2009 occurred along a fault line within the Eurasian Plate, which is a tectonic boundary between the African Plate and the Eurasian Plate. The earthquake was caused by the movement of the Eurasian Plate in relation to the African Plate.
At a convergent boundary between oceanic and continental crust where subduction is occurring.
the oceanic plate crased into the continental plate.
The plate boundary the Chile earthquake occurred on in 2010 was the converging boundary. A converging boundary is when two plates move closer together. In this case the converging boundary moved so close together that the plates hut one another. They then subducted under on another and the earthquake was formed.
Convergence plate boundary between the Eurasian Plate and the Indian Plate.
The Chilean earthquake had a magnitude of 8.8 and was a thrust fault earthquake that occurred at a convergent plate boundary where subduction of the Nazca plate under the South American plate is occurring. This type of thrust faulting at subduction zones is commonly referred to as a megathrust earthquake. Please see the related question for further information.

The Chilean earthquake was caused by subduction zone stress, where the Nazca Plate slid beneath the South American Plate. The fault associated with this event was a megathrust fault, specifically the interface between the two plates.
No, the 2011 Japan earthquake was a megathrust earthquake, specifically a subduction zone earthquake. It occurred along the boundary between the Pacific Plate and the North American Plate, where the Pacific Plate is subducting beneath the North American Plate.
One difference is: By the end of the year, 80% of the damage was either fixed or replaced, and Kobe did not take any donations that were offered to them. Haiti received £4.6 billion and still there is rubble taking up 40% of the country.
