2010 Haiti Earthquake

The Jan. 12 earthquake in Haiti alleviated built-up stress along one segment (blue gridded area boxes) of the Enriquillo fault, which cuts across the island. But scientists calculated areas (red boxes) on both adjacent segments of the fault in which stress and the likelihood of earthquakes increased, including one quite near Port-au-Prince.  (Figure modified from Lin, Stein, Sevilgen, and Toda, 2010)
