Some 200 Haitian engineers and engineering students gathered in Port-au-Prince on May 20-22 under a tent in plus-90°F heat to learn about seismic-resistant design and construction. The four introductory courses—which covered topics such as the seismology and seismicity of Haiti, earthquake-resistant design principles and rapid building assessment methodology—were held thanks to an agreement between the University of Quisqueya (UniQ) in Port-au-Prince and the University at Buffalo’s Multidisciplinary Center for Earthquake Engineering Research (UB-MCEER).
