A portion of Seaside Park shoreline in early spring 2012 (left) and after Sandy in November 2012 (right). To the north, a much smaller dune allowed storm waves and surge to push sand several blocks inland.  To the south, a wider dune buffer provided better overwash protection.  Images courtesy of the New Jersey Office of Information Technology, Office of GIS and the USGS Hazards Data Distribution System (HDDS).
