Axial Seamount Essay

There are 20 volcanoes scattered throughout northern, central, and southern California: Medicine Lake, Mount Shasta, Brushy Butte, Twin Buttes, Silver Lake, Tumble Buttes, Eagle Lake, Lassen, Clear Lake, Mono Lake, Mono Craters, Long Valley, Inyo Craters, Mammoth Mountain, Ubehebe Craters, Golden Trout Creek, Coso, Lavic Lake, Amboy, and Salton Buttes. Some of these volcanoes are active, while others are not. A majority of the volcanoes are inland, with Clear Lake Volcano being the furthest west, located near Sacramento and San Francisco. (Refer to figure 3 to see main .k California volcano locations.)

With no prolonged periods of inactivity the volcano has continuously built up on itself. The last major eruption took place in 1790 and killed many people and animals, but numbers are unknown4. Starting in 1983 there was a chain of several eruptions that started and have yet to stop pushing lava through a lava tube till it reaches the Pacific Ocean. Over a span of twenty year the flow has

The new volcanic material welling up into the void, which forms a ribbon of new materials and breaks down its center gradually, when the plates move apart from the axis of the mid-oceanic ridge system. Therefore, every separating plate accretes one half a ribbon of new lithosphere, and, thus, a new surface is added (Pitman, W.C, 2007). The process is continuous, and separation is always happening at the

Located in the Pacific Ocean, Hawaii and the Hawaiian Islands are the cone-shaped tops of gigantic ocean volcanoes.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

The west coast of North America has been tectonically and volcanically active for billions of years. The Sierra Nevada Mountains in eastern California were born of volcanoes, and magma has been erupting in the Long Valley to the east of the mountains for over three million years (Bailey, et. al., 1989). However, the climactic eruption of the region occurred relatively recently in the region's geologic history. About 760,000 years ago, a huge explosion of magma warped the Eastern Sierra into the landscape that exists today. The eruption depleted a massive magma chamber below the earth's surface so that the ceiling of the chamber imploded, forming what is now known as

It is located in the major area of the pacific ocean. A large number of earthquakes and volcanic eruptions happen here. It is a 25,000 mile horseshoe shape, it is associated with oceanic trenches and volcanic arcs. Nearly 90% of all earthquakes take place in this Ring. The Ring stretches from the southern tip of South America to the coast of North America, across the Bering Strait, down through Japan, and into New Zealand. There are also several active volcanoes in Antarctica.

Most of Earth’s volcanoes are located in the _______________ around the Pacific Rim just beyond the oceanic trenches, where magma, which is less dense than the

As the crust moves away from the volcanoes and cools and becomes less dense and breaks up.

The Axial Seamount is a very interesting landform. The Axial Seamount is an active volcano. Most people might think volcanoes would be above ground however, this volcano is actually underwater. The Axial Seamount was the site of the very first underwater volcano observatory. It is 300 miles from the coast of Oregon and is 1400 miles deep.

Since 1882, Mauna Loa has erupted 39 times. This volcano is a outstanding force of nature. Mauna Loa has amazed many people for mann years. This is a shield volcano, located on the beautiful island, Hawaii. As the Earth’s plates move, it causes more and more volcanoes to erupt. Mauna Loa is a breath-taking phenomena.

Kilauea is made on the pacific plate on a hotspot. Unlike most volcanoes kilauea is not formed on a boundary line. At hotspots magma rises up and eventually breaks the surface creating a volcano. Since Kilauea is a Hotspot volcano they grow in size very slowly, and will stay active for thousands of years.

Australia is one of the continents over the world. The vast, varied land and the culture in this abundant place has a deep and lasting impact to the architectural design traditions—Tectonic. Tectonic can be regarded as one distinctive characteristic which is relating to building or architectural construction. It also gives ability for people to read a structure, or see how a structure was put together. Among those architects who had used this tradition in their designs, Donovan Hill and Glenn Murcutt, as Australian architectures, have their own style relates to tectonic. For example, Donovan Hill composes different materials and layered against with one another in D House, while Murcutt establishes a harmonious connection to the surrounding landscape and local climate with Magney House.

the deepest marine trenches in the world (Rosenburg no. 6). With the interaction of the strong currents over the many reefs the topography is in a state of constant flux and development of new navigational hazards is swift (Rosenburg no. 6).
