The eruption started on March 19 when a new fissure 500 to 700 meters (1,600 to 2,300 feet) long opened in a valley on the island's Reykjanes peninsula. It happened in an area called Geldingadalir near the volcano Fagradalsfjall. There, molten rock flowed up through Earth's crust....
For most of its life prior to extinction, a volcano is in a dormant stage where it does little more than stand as a mountain or large hill in the landscape. When it wakes, it erupts. Eruptions can involve spewing lava, ash, smoke, gasses, chunks of rock, and volcanic glass.Answer and...
A phreatic eruption is just water and heat. Think of the inside of a volcano as a solid rock "oven" heated by magma. Earthquakes and shifting magma often jiggle and crack the rock. When a new crack opens in the oven, a blast of heat escapes, similar to opening a kitchen oven's door...

Why do earthquakes occur before a volcano erupts? Is Krakatoa an active volcano? What damage did the Mauna Loa volcano cause? What factors affect the eruption style of a volcano? Is Mount Etna a volcano? Why is Hawai'i Volcanoes National Park a world heritage site?
Why does the lava that flows slowly down the mountain cause far more damage than the boiling rock that erupts from the volcano? A. Because it buries everything in its path. B. Because most people live near the top of Mount Kilauea. C. Because the lava is in a higher temperature。 D....
aWhen a volcano erupts, dust is blasted high above the troposphere (对流层) and may take weeks to be carried around the weather zone, so cannot be washed out of the air by rain. It will eventually fall to the earth after a few years. 当火山喷发时,尘土在对流层(对流层之上)被炸开高...
aWhen a volcano erupts,the molten rock that flows from it is called lava.Then lava may run for some distance,or it may pile up near the volcano,making the mountain larger. 当火山喷发,流程从它称熔岩的溶解的岩石。然后熔岩也许为某一距离跑,或者它也许在火山附近堆,使山更大。[translate] ...
