Mount Kilauea基拉韦厄火山, the world's most active volcano, is on the island of Hawaii.It is not far from Mauna Loa莫纳罗亚山, the largest volcano in the world.Mauna Loa and Mount Kilauea together form the Volcanoes National Park in Hawaii.
Mount Kilauea has produced lava more than fifty times in the last one hundred years.Sometimes the lava moves slowly.At other times it pours out very fast as a huge amount of pressure forces it from the volcano.During these times, it moves almost as quickly as water moving down the side of mountain.Sometimes Mount Kilauea produces a large amount of lava that seems like rivers of fire.When the lava from Mount Kilauea reaches the ocean, its fierce heat produces a great amount of steam that rises into the air.The lava is so hot that it continues to burn underwater for some time.The lava from Mount Kilauea continues to add
land to the island as the volcanoes of Hawaii have always done.It was these volcanoes that formed the islands of Hawaii.Most of the time the lava of Mount 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 boiling rock slowly covered the town.It blocked roads and destroyed them.Nothing can stop the lava of Mount Kilauea.
Experts say the volcanoes of Mauna Loa and Mount Kilauea are a serious threat to property (财产) on many parts of the island.They also say the volcanoes of the island of Hawaii are proof that the changing environment of the earth is and will always remain beyond human control.
