夏威夷火山国家公园(Hawaii Volcanoes National Park)积极保护夏威夷火山环境。
夏威夷实际上是一个坐在火山上的州。夏威夷的132个岛屿都是数百万年火山活动的产物，其生成都来源于海底熔岩这个“热源”。
基拉韦厄(Kilauea)和冒纳罗亚(Mauna Loa)是阿罗哈州最著名的火山,位于夏威夷火山国家公园内。根据1952至1985年的记录，基拉韦厄火山共爆发50次，被认为是世界上最活跃的火山，自1983年以来沿着东部裂谷带连续喷发。基拉韦厄火山熔岩被动喷发的特点使其成为研究人员最注目的火山。
冒纳罗亚火山的容积超过83,350立方千米，顶峰海拔17,000米，是全世界最大的山脉。冒纳罗亚火山的活跃程度不如基拉韦厄火山，但科学家们认为， 700,000年以来冒纳罗亚火山一直在喷发。基拉韦厄火山和冒纳罗亚火山的熔岩火山活动继续为夏威夷增加一层又一层的熔岩。
夏威夷火山国家公园因其活火山、丰富的生物多样性和文化意义，在1987年被联合国教科文组织确认为世界遗产景观（World Heritage Site)。

Hawai'i Volcanoes National Park

Hawai'i Volcanoes National Park preserves the volcanoes that built — and continue to build — Hawaii.
Hawaii is a state founded on volcanoes — literally. The 132 islands that make up Hawaii are a result of millions of years of volcanic activity stemming from the same “hot spot,” an undersea hot lava source.
Kilauea and Mauna Loa are the Aloha State’s most famous volcanoes and both are located inside Hawai'i Volcanoes National Park. With more than 50 recorded eruptions from 1952–1985, Kilauea is considered the world’s most active volcano. Since 1983, it has been continuously erupting along its eastern rift zone. This passive outpouring of lava has made Kilauea a favorite volcano with researchers as well.
Boasting a volume greater than 83,350 cubic kilometers, Mauna Loa is the world’s most massive mountain. Its summit stands 17,000 meters above the ocean floor. Though not as active as Kilauea, Mauna Loa, scientists believe, has been erupting for the last 700,000 years. The fluid volcanic activity of both Kilauea and Mauna Loa produces layers of molten lava that continue to build Hawaii.
For its active volcanoes, rich biodiversity and cultural significance, Hawai'i Volcanoes National Park was designated a UNESCO World Heritage Site in 1987.
