I had to do a school paper and I want you people to tell me if its good. I know there are a few typo's
Kilauea is the most active volcano in Hawaii and perhaps one of the most active volcanoes in the world. A volcano is an opening where molten rock and gas comes from deep inside the earth. The molten rock, called magma, moves with great force through the cracks in the earth’s crust. The earth’s crust is the thin layer which we live on. Beneath it is the hot mantle, from which the magma comes from. Next comes the outer core, which is made up of molten iron and nickel and at the center of the earth is a solid inner core. When a volcano erupts it often sends out gas, pieces of rock, dust, ash, and lava. Lava is the name for magma when it reaches the surface of the earth. The lava cools quickly and forms a solid rock called igneous rock. The cross section of an erupting volcano has red hot lava blasting up through an opening in the earths crust. This opening is called a vent. Smaller side vents lead off fro the main vent. Sometimes the lava flows out quietly, but occasionally volcanoes explode with great violence when they erupt.
Kilauea is the youngest and most southeastern volcano on the Big Island of Hawaii. Kilauea appears as only a bulge on the southeastern area of Mauna Loa. The summit of it lies on a curving line of volcanoes which includes Mauna Kea and Kohala and not Mauna Loa. Its has erupted 61 times and is one of the younger volcanoes like said earlier. Kilauea is also believed to be the home of Pele, the Hawaiian volcano goddess. Hawaiian chants and oral traditions tell many eruptions were cause by Pele when she was angry. The eruptions of Kilauea have been continuous since January 3, 1983. Its caldera itself has no Hawaiian name other then Kilauea but houses the famous crater, Halema.
Kilauea is a shield volcano. Shield volcanoes are the largest volcanoes on Earth that actually look like volcanoes. In fact the Hawaiian shield volcanoes are the most famous examples. The shield volcanoes are almost exclusively basalt, a type of lava that is very fluid when the volcano erupts. Because of this these volcanoes are not very steep so you can't pile up the fluid that easily runs downhill. Eruptions for these volcanoes are only explosive if water somehow gets into the vent, otherwise they are characterized by low explosity fountining that forms cinder cones which spatter the vents. Because Hawaii is an island it is the perfect place for shield volcanoes to erupt because the water can easily get inside the vent and since Kilauea is one of the most active volcanoes and it is a shield volcano than having it near water is very dangerous since that means it could erupt anytime. On top of that Hawaii gets lots of rain so if the rain gets into the vents then the outcome could be terrible.
There is also risk zones of what would happen if Kilauea was to explode. Zone one is an extreme risk zone. It can contain intra crater earthquakes, extreme temperatures, toxic gases, falling projectiles, and unstable ground. You will be killed if you stay there long enough. Zone two is located on the light red part. Zone two is a high risk zone. If you happen to be in zone two during a larger than normal eruption you have a fifty percent chance of survival. This is as close to a volcano as you should get and you should stay in this area for only a short period of time. Zone three is a Medium risk zone and is shown by dark red paint. It is okay to spend a few hours here but you should watch the volcano and follow the instructions of guides at all times. We do not include level four zones on this map so there is no need to discuss them. Zone five is colored brown on this map. It is safe to live in. Zone five is only dangerous to be in, in a very large eruption. On are map the big pink blobs are villages. One of the villages, called volcano village, is in a zone three. Two other villages, called Keaau and Pahoa, are also in zone three but are not shown on our map. Since these villages are in a risky area we need a plan to get them out of danger. My partner and I have come to the conclusion that we should use two separate bus systems (one for volcano village and one for both Keaau and Pahoa) to transport everyone there to Hilo. People who live in Pahala, which is on the edge of a zone three, should be transported the same way to the safety of Naalehu. The Hawaii national park will have to be temporarily closed down as most of it is in a zone one, two, or three.
Throughout its history Kilauea has erupted from three main areas, its summit and two rift zones. Has Kilauea always had a caldera at the summit. It seems most likely that the caldera has come and gone throughout the life of Kilauea. The summit of the volcano is high because eruptions are more frequent there at any other location of Kilauea. But more eruptions actually occur on the long rift zones than in the summit area, though they are not localized, instead they are constructing ridges of lower elevation than the summit. Eruptions Along the east and southwest rift zones have build ridges reaching outward from the summit some 125 km and 35 km. Most eruptions are gentle, sending lava flows down slope from fountains a few meters to a few hundred meters high. Over and over there eruptions take place and gradually build up the volcano and giving it a shield like form. However every few decades to centuries powerful explosions spread eject across landscape. Such explosions can be lethal as the one in 1790 that killed many people who were near the summit of Kilauea.
