Why did the Haiti quake happen?

Answer 1

From msnbc.com: "Haiti lies on a complex tangle of tectonic faults near the intersection of the North American and Caribbean crustal plates. The area between the plates is a patchwork of smaller 'platelets,' such as the Gonvave Platelet. Haiti's 7.0-magnitude earthquake occured along the Enriquillo-Plantain Garden fault."

Why earthquakes occur: Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other. The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that's built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they continue to move until they get stuck again. The spot underground where the rock breaks is called the focus of the earthquake. The place right above the focus (on top of the ground) is called the epicenter of the earthquake.

Answer 2

haiti is the place between the Atlantic and the southern plate and plates crash into each other in other words haiti is at the cross and the last two extreme earthquakes in haiti were magnitude 6.1 and 7.1 and the worst place for earthquakes to cure

Answer 3

because haiti is on a ocean plate that is at a constant moving speed making the ground shake

Answer 4

cause the volcano is not developed all the way

Answer 5

I think it is because haiti lies on a fault line between two plates-the north american and caribbean.
