Sandy: Pre- and Post-Storm Photo Comparisons - New Jersey


USGS  

Hurricane Sandy's landfall affected the coastlines over a broad swath of mid-Atlantic and North-eastern states, including New York, New Jersey, Delaware, Maryland, Virginia, and North Carolina. Breaching, overwash and erosion took place on many barrier islands, including some that are heavily populated and developed. The pre- and post-storm photos below were taken over a 200 km (125 miles) stretch of New Jersey shore. These locations represent 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.

pre- and post-storm photos
Location 1: Oblique aerial photographs of Long Branch, NJ. View looking west along the New Jersey shore. Storm waves and currents removed sand from the beach exposing erosion control structures, including rock walls, concrete walls, and groins that protrude seaward perpendicular to the beach. The yellow arrow in each image points to the same feature. [larger version]

Location 3: Oblique aerial photographs of Mantoloking, NJ. View looking west along the New Jersey shore. Storm waves and surge cut across the barrier island at Mantoloking, NJ, eroding a wide beach, destroying houses and roads, and depositing sand onto the island and into the back-bay. Construction crews with heavy machinery are seen clearing sand from roads and pushing sand seaward to build a wider beach and protective berm just days after the storm. The yellow arrow in each image points to the same feature. [larger version]

Location 4: Oblique aerial photographs of Mantoloking, NJ. View looking west along the New Jersey shore. Storm waves and surge eroded the beach exposing building foundations, protective dunes, and houses in this part on Mantoloking. The burned houses are visible in the center of the bottom photograph. Only a few pilings remain of the first line of houses. Sediment was deposited on the island, remains on some roads, or has been cleared and placed in large piles in the parking lot behind the house marked by the arrow on the right. The yellow arrow in each image points to the same feature. [larger version]

Location 5: Oblique aerial photographs of Seaside Heights, NJ. View looking west along the New Jersey shore. Storm waves and surge destroyed the dunes and boardwalk, and deposited the sand on the island, covering roads. The red arrow points to a building that was washed off of its foundation and moved about a block away from its original location. The yellow arrow in each image points to the same feature.

Location 6: Oblique aerial photographs of Seaside Height Pier, NJ. View looking west along the New Jersey shore. Storm waves and surge eroded the beach and destroyed the seaward edge of the pier and deposited the roller coaster superstructure in the ocean. Sediment deposited on the island is visible in the background and indicates that overwash occurred here. The yellow arrow in each image points to the same feature. [larger version]

Location 8: Oblique aerial photographs of Brigantine, NJ. View looking northwest along the New Jersey shore. Storm waves and surge eroded the beach and exposed the seawall. Overwash of the seawall is indicated by sand deposited on the street. Low dunes on the eastern flank of the seawall were eroded. The yellow arrow in each image points to the same feature.
