An earthquake expert from the University of Colorado has urged the United Nations to act against the construction of weak buildings, particularly in earthquake-prone areas, The Vancouver Sun reports.
Roger Bilham visited Haiti post-Jan. 12 and inspected crushed buildings that are “doomed” right during construction.
“Every possible mistake was evident: brittle steel, coarse non-angular aggregate, weak cement mixed with dirty or salty sand and the widespread termination of steel reinforcement rods at the joints between columns and floors of buildings where earthquake stresses are highest,” he said.
