Why Haiti Collapsed After the Quake

A University of Illinois researcher back from Haiti says it was hard to separate his scientific work from the crisis surrounding him. Scott Olson is a professor of Civil and Environmental Engineering. He and a team of other geo-engineers examined if a process called liquefaction shook the Haitian soil so much that it could no longer support the structures on top of it - like the giant cranes at the capital's only port. The destruction blocked valuable aid from getting to victims. Olson sat down with AM 580's Tom Rogers to talk about the trip in both scientific and human terms.
