Haiti Quake - Reason for No Tsunami

Despite rumors of a tsunami, following the January 12 Haitian earthquake, none occurred because this quake resulted from a strike-slip fault.  The tectonic plates, in other words, slid past each other horizontally. 

For a tsunami to occur, a large amount of ocean water has to be displaced vertically during the deforming event.  That did not happen here.
