Volcanoes are one of the most disastrous yet captivating geological land forms on earth. Many volcanic eruptions are catastrophic, but not all volcanic eruptions are as brutal. The two case studies I have chosen to compare and contrast are the 1980 Mount St. Helens eruption with the eruption of Hawaii’s Kilauea volcano which is still active today.


Mount St. Helens is located in the Cascade mountain range in the southwestern region of Washington in the United States. It is known as the largest volcanic eruption to occur in North America on May 18th of 1980. Mount St. Helens is located on a destructive boundary where the convergent plate boundary, Juan De Fuca Plate, collided with the North American Plate (3). There are three different types

    Mt. St. Helens is famously for its eruption on May 18, 1980, although the mountain had previous eruptions with four different stages and the stages often had similarities including the devastating one in 1980; in addition, the 1980 eruption presented serious havoc that led to a long road of recovery. The first stage known as the Ape Canyon Stage and according to the U.S. Geological survey it was ignited from series of small eruptions that created the birth of the mountain; during this phase these eruptions possibly formed domes and pyroclastic flows. Mt. St. Helens in the Cougar stage formulated lava domes and flows just like the Ape Canyon stage including eruptions that escalated enormous volumes of ash along with pyroclastic flows; furthermore

    The difference of the 2 pictures is that picture 1 is very green with a skinny lake. In picture 2, everything is grey and the lake is much wider and is flowing much quicker. It also has a huge crater which was made because of a landslide. A science reporter named Eric Sorensen created a timeline on the events that occurred at Mount Saint Helens. It said: On the day of March 15, 1980, a frequent series of earthquakes hit Washington State. They grew stronger and stronger. Finally, a strong 5.1 earthquake hit a mile underneath the volcano. A hole in the icecap appears and a loud boom and a lot of ash occurs. Ice and rock slide into the crater. The booming and heat of the eruption cause a landfall which brought down the entire north face of the

    This explosion was very big but wasn’t its last.“The cataclysmic explosion of Santa María in 1902 was one of the largest volcanic eruptions of the 20th century.”(Jeannie A. J. Scott) This explosion impacted the mountain and the area around it. “ It devastated the surrounding landscape, and left a huge crater in the side of the mountain.”( Jeannie A. J. Scott). This explosion has damaged the mountain. ”Extrusion of the dome began in the center of the explosion crater created by Santa Maria's 1902 activity.”(WILLIAM I ROSE, JR.). This explosion was a major one in history. ”Flows, pyroclastic debris, and lahar materials directly associated with the Santa Maria composite cone occur on three sides of the dome.”(WILLIAM I ROSE, JR.). It has damaged itself and the area around it. Santa Maria is also near other volcanos and mountains. “The Central American volcanic arc runs through five countries: Guatemala, El Salvador, Honduras, Nicaragua, and Costa Rica (right). The Santa María / Santiaguito system lies at the northwest end of the arc, in Guatemala.”(Jeannie A. J. Scott). This large explosion of the volcano Santa Maria is intriguing and is a fascinating

    Volcanos are extraordinary geographic things. In Sioux City Iowa we do not have any volcanos. In fact we do not have any in the United States, but we do have some in Hawaii. A volcano works by the lower density of the magma relative to the surrounding rocks cause it to rise. Bubbles start to form from the gas dissolved in the magma. The bubbles exit in the magma with great pressure. Pressure helps bring magma to the surface or over the surface. Sometimes with tremendous pressure. Nevado Del Ruiz Volcano Eruption 1985 included many details common to volcano eruptions and caused damage and destruction to property and lives that affected

  • Mount Rainier: The Volcano Threatening Dense Populations

    480 Words  | 1 Pages

    The volcano that poses the greatest threat to humanity today is Mount Rainier because of its proximity to highly dense populations, its potential to erupt, and how it can spread disaster. Mount Rainier is categorized as a composite volcano, and it is also one of sixteen Decade Volcanoes in the world. Decade Volcanoes are under close watch by committees and disaster services because of their great potential to cause catastrophic disasters in the area in which they lie (National Park Service [NPS]). Mount Rainier sits next to the large cities of Tacoma, Seattle, and their suburbs, and they are all in distance of the potential danger of the volcano (Driedger and Scott, 2008). The volcano also relies on its drainage system, the Columbia River, to spread disaster, so parts of Oregon and southwestern Washington are also unsafe from the danger of a Mount Rainer eruption (NPS). Mount Rainier’s eruption potential is also what makes it such a dangerous volcano. Geothermal activity of the volcano indicated that it is still active, and it is in between its eruption cycle (NPS, Driedger and Scott, 2008). Scientists think a Mount Rainier eruption will be less explosive than in past events, but because of the

  • Volcanoes: The Deadliest Features Of The Earth

    780 Words  | 2 Pages

    Considered to be one of the deadliest features of our Earth, volcanoes are not only beautiful in their own way, but they are certainly unpredictable and dangerous. Volcanoes are formed to ventilate the pressure that is within the earth’s mantle. Firstly, volcanoes can start out at mountains, and with time, these mountains can erupt, causing molten rock and magma to ooze out and flow towards the Earth’s surface. After the release of this contained pressure form within, then lava spews out, along with an abundant amount of ash, which can travel for miles through the air, covering almost everything in sight. Volcanoes have been around for hundreds of thousands of years, but volcanologists still learn new things about them each and every day.
