What caused the Haitan earthquake?

Yes. It was a considerable movement along the Haiti/ Dominican Republic Fault. It was mostly a slip (horizontal) movement fortunately. Haiti was destroyed because the old buildings were not earthquake resistant.

The quake in Christchurch, NZ (my home town) and the one in Japan recently also were caused by movement on various faults. The Japan quake raised the seafloor off the country by as much as 50m and had a length of some 400km. That's a lot of water tossed onto the land nearby.  :o

The Christchurch quake was caused by a strike/slip movement along the Darfield fault. The land under Christchurch moved 8m westward and 3m upward.
