70 Percent of the Beaches on Oahu, Maui and Kauai are Eroding

"The report National Assessment of Shoreline Change: Historical Shoreline Change in the Hawaiian Islands summarizes historical shoreline changes on the three most densely populated islands of the eight main Hawaiian Islands: Kauai, Oahu, and Maui. The report shows that 70 percent of beaches on the islands of Oahu, Maui and Kauai are undergoing long-term beach erosion. The average rate of coastal change was 0.4 feet of erosion per year from the early 1900s to 2000s. Of the three islands, Maui beaches experienced the highest rates and greatest extent of beach erosion with 85 percent of beaches eroding. Erosion is the dominant trend of coastal change on all three islands with 71 percent of beaches eroding on Kauai and 60 percent of beaches eroding on Oahu." More Hawaii erosion data here.
