caused nearly $2 billion dollars of damage in 1992. It was classified as a Category 4 hurricane with winds of up to 145 mph. Hawaii has seen large scale damage and loss of life from tsunamis in 1946, 1952, 1957, 1960, and 1975. It has also been threatened by tsunamis in recent times because of massive earthquakes in Chile (2010) and Japan (2011). Large earthquakes are another threat. The most recent was a 6.7 magnitude earthquake that occurred on the west coast of Hawaii Island on October 15, 2006, which caused property damage and large- scale power outages. Saltwater may not have the visual impact of lava flows and tsunamis, but over time, its presence results in corrosion damage to galvanized equipment in locations near the ocean. These areas thus generally require the use of more costly equipment fabricated from stainless steel. Population Demographics Between 2014 and 2018, Hawaii's average population was 1,422,029. This population was highly concentrated on the island of Oahu, where approximately 70% of the population resided. The remaining 30% of the population was spread throughout the rest of the State. Hawaii also has a large visitor population because of its significant tourism industry. It is estimated that in 2018 Hawaii had an average of 240,341 visitors present in the State per day, and 9,761,448 visitors in 2018 who stayed overnight or longer. The State's four counties are roughly designated by island: • County of Kauai (the islands of Kauai and Niihau) • City and County of Honolulu (the island of Oahu) • County of Maui (the islands of Maui, Molokai, Lanai) • County Hawaii (the island of Hawaii) The 2014-2018 average population density by county and by island is as follows: Wj-*M
