I. Summary
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.
II. Introduction
The central area of the Pacific Ocean is the home of the Hawaiian Islands that span 2,400 kilometers long beginning at Kure Island, located in the northwest and forms a southeast-trend line to big island of Hawaii (Edge of Fire). This island is 3,000 kilometers away from the nearest continent, which is North America. Due to this curve of the islands the area is broken into two areas known as the “northwestern (leeward) islands” and the “southeastern (windward) islands.” The existence of islands of Hawaii is due to the claimed “hot spot” that began form...

“Hawaii’s Big Island” got that name to keep down confusion from the actual state name. The Big Island is bigger than all of the other Hawaiian islands put together. Hawaii’s Big Island is filled with Hawaiian temples from ancient days.

Mauna Loa is located on a hot spot in the Pacific Ocean. It is not near a plate boundary, in fact it is 3,200 km from the nearest plate boundary, and is situated in the middle of the Pacific tectonic plate. This is actually a rarity, as 90% of volcanoes are along a tectonic plate boundary. A hot spot occurs where long, stationary vertical pools of magma rise up and towards the plate. Movement of the tectonic plates above the hot spot created Mauna Loa, along with the other Hawaiian volcanoes. The older Hawaiian Islands were once above this stationary hot spot, but have been carried northwest by the slowly moving Pacific plate. As the plate moves, it carries the previously formed, older, volcanoes with it, creating a trail of younger, new volcanoes behind. The islands are lined up along the Hawaiian Ridge-Emperor Seamounts chain, which is 3,750 miles and includes Kauai, Maui, Oahu and Hawai’i, from north to south, respectively. There are around 80 volcanoes in this chain; most of them underwater, consequently the term seamount refer to submarine volcanoes. Three volcanoes of Hawai’i, Mauna Loa, Kilauea and Loihi seamount, are all currently sharing the Hawaiian hot spot. Although, recent evidence has shown that all three volcanoes use have separate plumbing systems to expel the lava from the pool of magma deep below them. It has also been suggested that Loihi is slowly moving Mauna Loa from the center of the island, thus shifting directly over the hot spot. The closer to the hot spot a volcano is, the more active it will be. The Hawaiian hot spot has laid down layers of lava, building up enormous islands from the ocean floor.
American Hawaii Hawaii is known for its beautiful beaches, it’s nice year-round weather, and its culture. Thousands of vacationers come to Hawaii each year to get away from the stressful city and relax. But do they know how cruel the Americans were to the natives? Do they know how we corrupted their culture and their religion? Do they know how Hawaii really became a state? Probably not. When most people think of Hawaii, they think of happy Hawaiian babes hula dancing and palm trees swaying in the warm breeze. Hawaii has still held on to many of their traditions although they were invaded by Americans. But you have to go to a museum to see their old way of life. Hawaii is now populated mostly by Americans. Native Hawaiians have adapted to our American lifestyle and much of their old traditions and beliefs are lost in history books. America dominated over the Hawaiians just as they did with the Native Americans. The Hawaiians didn’t even stand a chance against big brother. They probably feel the same way towards America just as a child does with stubborn parents. Now I will tell you about the history of Hawaii so you will see how the United States came to annex Hawaii. Hawaii was first inhabited by the Polynesians. They came in canoes from other islands around the pacific. They called the new found island "Hawaii", which means "home" in Polynesian language. Hawaii was their home until the white man came in and took advantage of these simple, happy aborigines. The corruption of this unique and fragile culture first started when Captain James Cook ran into the islands on January 18, 1778. After Cook’s discovery, many other foreigners (mostly American) visited the islands. They brought clothes, livestock, orange trees, horses weapons and souvigners. Foreigners also brought with them a handful of deadly diseases such as smallpox, measles, syphilis, tuberculosis, and whooping cough. During the time period of Cook’s arrival in 1778 to 1820, the population of Hawaii dropped from 300,000 to 135,000 due to the diseases! Another problem was the introduction of alcohol. Like the native americans, Hawaiians were not immune to alcohol. Hawaiian’s were very sensitive to alcoholism. Hawaiians religion was a very complex one with many gods. They worshiped idols and they belived in many f...

The west coast of the islands is on the edge of a continental shelf created by ancient volcanic movement (Broadhead 5) .This volcanic activity is due to plate tectonic movement which also created the numerous amounts of earthquakes on the island. Compared to the rest of British Columbia, Haida Gwaii has the most earthquake activity (Broadhead 5), the last of which being in a magnitude of 7.7 on t...
Maunaloa last erupted in 1938 and Kilauea has been erupting since January 3,1938. The Hawaii Volcanoes National Park was named a World Biosphere site by UNESCO in 1987. Kilauea is also called the world's only drive-in volcano.

Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Volcanoes are one of natures most interesting and dangerous phenomenons. The way volcanoes operate can be understood, on a basic level, by just some simple physics and chemistry, this paper will investigate and explain some of the basic physics that govern the behavior of volcanoes.
The earliest outcropping volcanic deposits date back to about 25,000 years ago. The lavas observed at a -1125 m bore-hole are about 0,3-0,5 million years old. It is known for the first eruption of which an eyewitness account is preserved, in 79 AD. Geologically, Vesuvio is unique for its unusual versatility. Its activity ranging from Hawaiian-style release of liquid lava, fountaining and lava lakes, over Strombolian and Vulcanian activity to violently explosive, plinian events that produce pyroclastic flows and surges.
