Unraveling Complexity of Haiti Quake Reveals Hidden Faults and Future Hazards

The January 2010 M7.0 earthquake that devastated Haiti’s economy and caused over 200,000 casualties also resulted in significant uplift of the ground surface along Haiti’s coastline, and involved slip on multiple faults, according to a study published online in Nature Geoscience. Because the earthquake did not involve slip near the surface of the Earth, the study suggests that it did not release all of the strain that has built up on faults in the area over the past two centuries, and so future surface rupturing earthquakes in this region are likely.
