According to this article: Purdue researchers studied Haitian fault; warned of potential for a large earthquake the fault that resulted in the Haiti earthquake was a known concern among earthquake scientists.
Those in the know were especially concerned due to Haiti's extreme poverty, leading to buildings not built to modern earthquake standards, plus tens of thousands living in slums on the outskirts of the city. This level of poverty didn't happen by itself. Haiti has been exploited by colonial imperialism since 1804, chiefly by the United States that has used Haiti as an unfettered source for cheap labor and raw materials.
As if that wasn't enough, now the Heritage Foundation releases this bit of screaming "Shock Doctrine," saying now is the time for the United States to take over militarily and reshape the devastated government and people in our (read, their) image.
Not only will we kick them while they're down, we'll take away their culture and government, to boot.
