As soon as the winds that left seven students in Moore, Okla., dead last month had calmed, and more storms blew through the same area less than two weeks later, questions about the safety of schools in a region labeled Tornado Alley rose amid the rubble. While better design of new schools and thorough emergency training and practice may be in order, more shelters aren't necessarily the answer, experts and educators say. Schools and communities across the country prepare for tornadoes in different ways. Some design a common room at a school to serve as a shelter, while others create underground safe rooms or fortify buildings to withstand relatively weak storms.
