A top engineer from the city of Los Angeles visited Cornell University this month as researchers tested a unique earthquake-resilient pipeline designed to better protect southern California's water utility network from natural disasters. They ran multiple tests, including an earthquake simulation in which a 28-foot-long section of the pipe was outfitted with more than 120 monitoring instruments and buried within 80 tons of soil - an experiment that took over a month for the research team to prepare.
