Lessons from January 2010 Earthquakes in Haiti and Offshore Northern California
8 – 8:30 a.m., Salon A, E, F and G
A field reconnaissance was conducted in Haiti Jan. 26 through Feb. 3, 2010, by a five-member team with expertise in seismology and earthquake engineering. This study has revealed a number of factors that led to catastrophic losses of life and property. Soil liquefaction, ground motion amplification, triggered landslides and rockslide, and soil embankment failures were observed to be significant factors contributing to extensive damage in Port-au-Prince and elsewhere. The historic pattern of prior earthquakes in Haiti indicates that a strong earthquake with M7 or larger could strike southern Haiti near Port-au-Prince at any time.
