A few different articles about new studies on the erosion caused by Hurricane Ivan have been floating around the past few days. This one is from CNN:
The erosion caused by Ivan’s waves and storm surge undermined five-story oceanfront condominium buildings, “the largest buildings to fail during a hurricane in United States history,” Sallenger said. He said the average shoreline erosion was 42 feet in the area where Ivan came ashore, roughly between Alabama’s Mobile Bay and Florida’s Pensacola Bay in Florida.
