Scientists had thought the Haiti earthquake a year ago released stress on a well-known fault. It didn't. Instead, it revealed faults that scientists didn't know existed.
The forces that led to the Haiti earthquake are a reminder that the idyllic Caribbean is one of the more geologically active spots on earth, and that a powerful earthquake could strike the region again.
The same earthquake fault that lies under Haiti also runs through the Dominican Republic. Geologists warn that the Haiti quake – at the Enriquilla-Plantain Garden Fault – may have added strain elsewhere and more quakes are possible.
