An alarming study, released last week, reveals that 70 percent of beaches on Maui, Kauai and Oahu are experiencing long-term erosion.
The study says 85 percent of beaches on Maui are eroding, while more than 70 percent on Kauai are eroding. The study says 60 percent of Oahu's beaches are eroding. Scientists studied more than 150 miles of island coastline, and essentially every beach.
While a small percentage of beaches had built up or stayed roughly the same, the average rate of coastal change was 0.4 feet of erosion per year from the early 1900s to 2000s.
The new analysis, "National Assessment of Shoreline Change: Historical Shoreline Change in the Hawaiian Islands," is the latest in a series of reports the geological survey has produced for the Atlantic and Gulf Coasts, California and some of Alaska.
