Coastal imagery of pre- and post- storm conditions from Hurricane Sandy.
Photos pairs are used to compare the pre-storm and post-storm conditions at locations representing a broad range of coastal configurations and their response to the storm. Pre-storm photos were acquired during a baseline survey May 21, 2009 and post-storm photos were acquired November 4-6, 2012.
The USGS acquired an airborne LIDAR survey of post-storm topography of Fire Island on November 5, 2012, to measure coastal change resulting from Hurricane Sandy. Comparisons of the post-storm elevation data to LIDAR data collected prior to Sandy’s landfall are used to characterize the nature, magnitude, and spatial variability of hurricane-induced coastal changes, such as beach erosion, overwash deposition, and island breaching. These measurements complement field-based observations of coastal change that were collected immediately prior to and three days after landfall.
