Essay On Mauna Loa

On May 18th, 1980, Mount Saint Helen, a volcano in Washington erupted majorly. The eruption is the most studied volcano eruption. Mt. St. Helen was known as one of the most prestige volcanoes in the Cascade Range before its eruption on May 18, 1980. The eruption made a big blast that destroyed the northern part of the volcano, crushing millions of the trees below the mountain. The zone was further described as a big debris avalanche.

The deeper source of Kilauea’s eruptions, as with all of Hawaii’s volcanoes is this mantle plume. It’s a blob of hot rock that has risen from the deep inside the Earth and is now torching the Earth’s crust. The mantle plume goes down to near 1,500 kilometers deep and is the biggest one yet that scientists have ever seen. The way the scientists found out how big this plume was by using an array of seismometers on the ocean floor. IV.

Popocatepétl 19° N, 98° W - Satsang Adhikari Popocatepetl is located in Puebla, Mexico. It is a steep-sided stratovolcano, with the elevation of 5,426 meters, which is a part of the Trans-Mexican Volcanic Belt that extends 900 km from east to west across central southern Mexico. It is also one of the 452 active volcanoes surrounding the “Ring of Fire”. NASA considers Popocatepetl to currently be the planet’s “most riskiest volcano”.

This volcanism has included such notable eruptions as Mount Mazama (Crater Lake) about 7,500 years ago, Mount Meager about 2,350 years ago, and Mount St. Helens in 1980. Major cities affected by a disturbance in this subduction zone would include Vancouver and Victoria, British Columbia; Seattle, Washington; and Portland, Oregon. The two tectonic plates involved in the subduction process at the convergent fault line are the Juan de Fuca plate and the North American plate. The Juan De Fuca plate being the denser oceanic plate is being subducted under the continental North American plate. Although the fault line is on the coast of the Northern American plate tectonic activity is also heavily present inland, evidence of this is the cascade volcanic arc formed by the tectonic movements at the fault

On May 18th, 1980, thirty-five years ago, Mt St. Helens erupted and changed the course of history. This towering Washington volcano is part of the Pacific Ring of Fire. During the eruption the mountain spewed hot gases, rocks and, ash into the sky causing a mud flow down the mountain 's sides. According to the National Oceanic and Atmospheric Administration," this was the deadliest and most economically destructive volcanic event in the history of the United States".

During the daytime, you get to look down at the clouds, as well as the impressive volcano Mauna Lua across the plain. Mauna Lua is the world’s largest volcano and mountain when speaking of mass. When on the summit at night, you may be able to see the glowing lava flowing from Mauna Lua.

Firstly, in order to understand the Mauna Loa, one must know the type of volcano it is. The Mauna Loa is a shield volcano, with wide moderate sloping sides. Shield volcanoes are created when lava emerges out from fissures in

The volcano I pick was Mt Mauna Loa. This volcano has erupted about 32 times for the eruption of 1984. Mauna Loa is about 600,000- 1 million years old and hasn’t erupted as much as Kilauea and when it erupts it produces huge rivers of lava and threatens towns nearby. Mauna Loa is the second tallest volcano in the world. The elevation is 13,679 feet high.

There are three different types of volcanoes that can be formed. I think that Mt.Tambora is one of the biggest and strongest volcanoes ever seen although it erupted over 200 years

Being the tallest mountain Mauna Kea is a big part of the Hawaiian history and also a big part of world history. Mauna Kea is a dormant volcano, the last time it says to have erupted was about 4,600 years ago. Since its last eruption Mauna Kea has evolved into more than just a volcano, it has also become home to some of the world 's best telescopes and has also been

The hot material deep within the surface of the Earth melts to produce magma beneath the Pacific Plate. Each of the volcanoes in the Hawaiian island chain go through a series of stages in their lifetime. In short, the shield stage, postshield stage, erosional stage, rejuvenated stage, coral atoll stage, and the guyot stage. The shield stage is divided into three phases, the submarine, explosive, and subaerial. Following the gentle explosions of the pre shield stage, the submarine phase begins with pillow lava eruptions.

Maybe you’ve read up about Mount Vesuvius or read the news articles about Mount St. Helens. Maybe some of you also think of Crater Lake, Lassen Peak or Trident in Katmai. Volcanoes are incredibly diverse, but most people picture composite volcanoes as the default shape. The Yellowstone Volcano is considered a super volcano, because it can produce more than 240 cubic miles of magma in an eruption, but because it is so large, the most visibly distinguishable feature is the Yellowstone Caldera.

How would you like to live on the side of a volcano? On The Big Island of Hawaii, people can experience this during their vacation at KMC, a military camp located near the volcano Kilauea. There are currently three active volcanoes in the state of Hawaii, all of them being on or very close to the Big Island. Mauna Loa is the oldest of them, Kilauea is the most active, and Loihi is so young in comparison to the others that it hasn’t even breached the ocean’s surface. As of 2017, The Big Island is home to a population of 186,738 while 953,207 people live on the nearby island of Oahu.

Many science organizations have agreed that the probability of another super eruption is a low probability chances are quite slim with estimates being a minimum of 1 in 730,000. Technology has gotten better and scientists are better able to detect a possible eruption before it happens due to the many warnings that would appear. There are some warnings before volcanic eruptions occur such as multiple minor earthquakes, land uplift, gas releases through the many small holes which help relieve pressure. In an article by the NSF which stands for National Science Foundation scientists believe that another eruption wouldn’t occur for another 1-2 million years because based on research of its caldera cluster the volcano is undergoing its dying cycle rather than its ramping up cycle. The foundation states that “by studying the pattern behavior of the cycles and its previous eruptions by examining the rock minerals in the vicinity they’re given better clues to suggest the volcano is on its calm stage”.

The eruption removed 1,300 feet of the summit leaving a horseshoe-shaped crater and a barren wasteland. This famous mountain got it 's name from Native Americans in the Pacific Northwest, they
