Natural disasters are affecting communities across the United States more often. New research says safer homes need both stronger structures and smarter regulatory systems. The study was led by Susan Ostermann and civil engineering professors María J. Echeverría and Abbie Liel at the University of Notre Dame. It was funded by the National Science Foundation and appears in the International Journal of Disaster Risk Reduction.
The team focused on Anchorage, Alaska, where a magnitude 7.1 earthquake in 2018 destroyed or damaged more than 750 homes. Many residents did not trust government rules, and the researchers say stronger codes alone do not ensure safer construction when rules are not followed. The researchers interviewed nearly 40 experts and found many homes lacked simple safety features like shear walls, proper garage framing, and hold-downs.
