Kilauea is the youngest volcano on the Big Island of Hawaii. Still active, there have been 34 eruptions since 1983. Kilauea is a shield volcano, meaning it covers a wide range of area, and has sloping sides. Kilauea is usually confused as being a smaller part to the neighboring Mauna Loa volcano, but it has it’s own lava flow system which makes it special to the Hawaiian islands. The history of eruptions from Kilauea is lengthy and the volcano’s name actually means, “spewing.” The oldest documented samples of lava date back almost 3,000 years and the oldest human documented eruption happened in 1823. The caldera at the Kilauea summit crater has a lava lake, continuously smoking. The crater is named “Pu’u O’o” and is called a spatter cone, which is a typical cone that is associated with volcanoes with highly fluid magma. The partial liquid molten rock that splashes down the sides of the cone is called “spatter.” This constant state of lava has an incredible impact on the eco system around the volcano. Growing ecosystems are often interrupted by sulfur dioxide, which is produced by the volcano. This produces acid rains south of the volcano in an area known as the Ka’u Desert. This desert is filled with tephra, which is volcanic fragmental material that is made during an eruption. Ironically the opposite happens around other areas of the volcano and island where volcanic soil and rich volcanic elements provide an environment for wildlife to flourish. Another key geological phenomenon is the vast ecosystems that thrive off of the volcano. The southernmost ecosystem lies within the Hawaii Volcano National Park and is host to an extensive assortment of bird species including the endangered ‘akepa, ‘akiapola’ay, nene, ‘ua’u, and... ... middle of paper ... ...ad steam rising from it and vegetation was sparse. It was scary, but thrilling at the same time. Less than a mile away was the caldera and it was very surreal knowing that within running distance was volcanic lava boiling beneath the surface of the Earth waiting to one day erupt again. The ground was flat and cracked all around. We turned back up the dirt path to head up the trail into the foliage of the forest again, finally finding our way back after over an hour of searching and pondering. The Hawaiian islands are unlike any other place in the word in person. So much foliage and wildlife exists that you cannot find anywhere else, and each island is unique in its own little way without any controversy. This experience with my husband showed me how geologically diverse a given area of land can be and how nature can affect an ecosystem over a long period of time.
On the morning of June 6th, 1912, the ground of the southern Alaskan peninsula began to shake with extreme force. This force, when later analyzed, turned out to be the most powerful volcanic eruption of the 20th century. This newly formed caldera volcano, later known as Novarupta, literally translated as “new eruption”, is located in Katmai National Park and Reserve on the Alaskan Aleutian Range (Pidwirny and Jones 2009). Novarupta’s eruption caused immediate impacts to the native Alaskan climate as well as impacts to Earth’s global climate overall. Volcanoes can leave enormous impacts locally to geography and ecosystems, but because of Novarupta’s status as the strongest volcanic eruption in Alaska’s recorded history, Novarupta left local as well as global impacts on Earth’s climate.
Quilotoa Lagoon, located in the crater of the volcano has an interesting geological history. Ten thousand years ago, the volcano erupted violently, sending a huge pyroclastic flow on the volcano 's slopes. The effects of water and wind over the rubble of the eruption, created the white walls that can be seen in the river canyons and mountains in the vicinity of the volcano. An eruption of Quilotoa (800 BC), was the explosive event larger scale than has been believed in pre-Columbian Ecuador. During this event, the ash traveled hundreds of kilometers north of Quito. These ash layers provided interesting clues for archaeologists and geologists Ecuador, about life in earlier
Molten rocks pouring from faults in the earth’s surface causing massive shivers in the crust and deadly clouds in the sky. Volcanoes cause a lot of damage both to our environment and to ourselves. The damage one eruption causes is massive. Volcanoes don’t erupt very often on land, but in the water there are thousands that explode every year. These underwater eruptions can sometimes grow so big they break the surface of the water and create islands like Hawaii. The clouds of ash created through these eruptions start out deadly and can overload your lungs but after they have settled they create extremely fertile soil.
If you’re looking for adventure, look no further than the volcanoes in Hawaii. You can actually get to see a volcano up close. When they get angry, it is a sight to see. They can cause a lot of ruckus on the islands. When the volcanoes erupt, they can harm the natural wildlife on the Hawaiian Islands.
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
...in the region have become fruitful where the volcanic ash had built up and the marine life can develop from the iron and the silica from the volcanic ash. The caldera eruptions have only happen two to four events per million years.
The Hawaiian Volcanic Islands were first formed through volcanoes that arose from the Hawaiian hot spot on the seafloor of the Pacific Plate. Organisms then populated the area through a long process called Primary Ecological Succession, which turned the islands into beautiful and verdant ecosystems. Since disturbances, either man-caused or natural, are always affecting those ecosystems, Secondary Ecological Succession is in perpetuate use to enable the Hawaiian Islands to thrive.

This paper will provide information on the volcanoes of Hawaii, where it is known to be the home of one of the world’s largest volcanic islands, merely second to Iceland. It is not just the beautiful landscapes and wildlife that spark the interest to this particular area, but the uniqueness of the Hawaiian volcanoes and islands themselves are what make the area so significant. There will be information spanning from the history of the origin of the islands to how Hawaii must adjust to the volcanic hazards in order to keep the area livable. With these ideas in mind, I will first address background information on the area and set the scene as to what makes this area so special. Then I will transition to the history of how the Hawaiian Islands were formed, and transition to the active and previously active volcanoes on the islands. From this point, the paper will move towards the volcanic activity of Hawaii and the life stages of the volcanoes. Once that is established, the paper will discuss the historic eruptions of Hawaii. Finally, the paper will conclude with how Hawaii must cope with the volcanic hazards in order to keep Hawaii a habitable area.

Volcanoes are magnificent and powerful land features. The magma erupts from the Earth forming islands, cooling to form rocks, and changing the landscape on eruption at a time. They can erupt at any time! Since volcanoes are dangerous we have developed technology to detect these impressive explosions. Since Hawaii was formed by a volcano when you visit Hawaii you are standing on cooled lava! There are 3 different stages a volcano can be in and 2 very different types of explosions that can happen. Volcanoes are magnificent and have beautiful features.
A highlight of many Hawaii tours is seeing an active volcano and Kilauea does not disappoint. Located within Hawaii Volcanoes National Park, Kilauea's summit lava lake rises and falls with the unseen pressures deep within the earth's crust. Kilauea is one of the most active volcanoes in the world and most Hawaii tours will include views of the plumes of smoke and ash rising from its crater peak. If you are there on a day when Pele the goddess of fire is unappeased, you might just see a living lava flow.
The first place that came to my mind when I thought of a geology on Maui was the ʻĀhihi-Kīnaʻu Natural Area Reserve. Well, actually that is a lie, the first place that came to my mind was the top of Haleakalā but I did not plan on travelling all the way up there. However, as is most of the island, ʻĀhihi-Kīnaʻu is still closely related to the immense shield volcano Haleakalā. My visits to the reserve have been few in the past and they were usually prompted by distant family visits. Without the pressure of hosting relatives, I was awarded the chance to take in the site at my own pace.
Volcanoes are catastrophic events in time . Although how dangerous volcanoes can be they attract huge groups of tourists every day . There are different types of volcanoes and different volcanic eruptions and are all horrific . Volcanoes can affect everyone and everything in it’s path . Volcanoes can be found all over the world and there are volcanoes forming this very second. Volcanoes bring curiosity to everyone .
Throughout the world there are a variety of natural disasters that occur among the environment on a daily basis. Some may only cause minimal harm, but others could be extremely destructive to the point where it could cause certain deaths and ruination. Among the several natural disasters that are known, volcanic hazards have become one of the most concerning threats here in the United States and in the world. (Myers) This has sparked my interest because it was interesting to learn about how intrusive and troubling volcanoes, explained thoroughly in chapter four of the textbook, can be and how it impacts the planet we live in. Throughout this essay, I will describe different kinds of volcanic hazards, how
