Hog Island, a 1600m long island south of Rockaway Beach, was never seen again after the hurricane of 1893. All that remains are a few antiques that washed up on the beach.
On August 23, 1893, a Category 2 hurricane hit new York City, sinking boats, killing sailors and uprooting trees in Central Park. Hog Island got the worst of it though. It simply ceased to exist after the hurricane. It was washed away in one day.
New York rarely gets hit by hurricanes. The statistical average time between hurricanes hitting New York is about 75 years. Another hurricane hitting New York now would cost an estimated $11.6 billion in damages.
