During these times, it moves almost as quickly as water moving down the side of a mountain. Sometimes Kilauea produces large amounts of lava that seem like rivers of fire.
When the lava from Kilauea reaches the ocean, its fierce heat produces great amounts of steam that rise into the air. The lava is so hot it continues to burn underwater for some time. The lava from Kilauea continues to add land to the island as the volcanoes of Hawaii have always done. It is these volcanoes that formed the islands of Hawaii.
Most of the time the lava of Kilauea seems to move peacefully toward the ocean. Yet it is not as peaceful as it seems from a distance. In recent years the lava destroyed one small town on the island. The liquid rock slowly covered the town. It blocked roads and destroyed them. Nothing can stop the lava of Kilauea. Experts say the volcanoes of Mauna Loa and Kilauea are a serious threat to property on many parts of the island.
Experts say the volcanoes of the island of Hawaii are proof that the changing environment of Earth is, and will always remain, beyond human control.火山熔岩有时移动缓慢，有时又会在火山内部的巨大压力下，急速喷涌。这时熔岩的移动速度几乎和山上奔流而下的水流速度相当。有时候基拉韦亚火山会喷发出大量熔岩，犹如一条火焰之河。
当基拉韦亚火山的熔岩流至大海，炙热的高温产生了大量的蒸汽，升入空中。熔岩温度极高以至于在水下依然会燃烧片刻。基拉韦亚火山的熔岩不断增加着岛屿的土地面积，如夏威夷火山的一贯做法。也正是因为这些火山，才形成了夏威夷群岛。
大多情况下，基拉韦亚火山熔岩似乎都平静地流向了大海，但其实它并不像从远处看到的那样平静。近几年，熔岩摧毁了岛上的一个小镇。岩浆缓缓地吞噬了整个城镇，阻塞并破坏了道路，熔岩所向披靡。专家称莫纳罗亚火山和基拉韦亚火山对岛上大部的地区财产存在严重威胁。
专家还表示夏威夷岛上的火山表明，对于地球环境的变化，人类目前无法控制，也将永远无法控制。
