This year's devastating earthquake in Haiti was caused by a previously unknown fault, according to scientists.
This discovery, the researchers say, could be the first sign of a larger system of seismic faults in the area.
The Enriquillo fault, which runs through Port au Prince, was originally blamed. But new evidence has shown that it was not linked to the event.
Eric Calais from Purdue University in Indiana, presented the findings at an scientific meeting in Brazil.
At the American Geophysical Union's Meeting of the Americas in Foz do Iguacu, he explained that the earthquake was more complicated than previously
He said that the first "give-away" was the fact that there was no surface break along the known Enriquillo fault. This led to a search for other
faults or fractures in the Earth's crust, which may have slipped and caused the event.

This seems like pretty significant news. If this fault line was unknown, then how many others are also "unknown", in places we think that we are
Anyway, this is pretty interesting and I would hope that it could further our knowledge about the theory of plate tectonics.
