| Description: |
Ever since lava first erupted above sea level over 500,000 years ago to begin building the Island of Hawai`i, countless eruptions from its five volcanoes have built the "Big Island" to a towering height of more than 4,000 m (13,000 ft). Its two most active volcanoes -- Mauna Loa and Kilauea -- erupt lava frequently enough to pose a serious hazard to property on many parts of the island. About 40 percent of Mauna Loa has been covered by lava in the past 1,000 years and over 90 percent of Kilauea's surface is covered by lava less than 1,100 years old. As land development expands toward areas of relatively high hazard, the threat to life and property on Hawai`i will increase accordingly. |
