On the afternoon of April 10, 1815 an event occurred that would change the lives of many people. This event was forevermore engraved in the history books and remembered as the eruption felt around the world. On this day Mount Tambora exploded killing thousands of lives, and destroying the entire surrounding environment, and is still known to this day as the most powerful volcano eruption in history. There are many curious people that still ask themselves “what caused this devastating eruption”? Its simple, the volcano eruption wasn’t something we caused, but rather something Mother Nature itself caused. Mount Tambora is known as a stratovolcano (really dangerous and unstable), inside this volcano there's this huge magma
The governor of Java sent an officer to one of the neighboring islands Sumbawa to check the condition it was in. “He found there were still dead bodies lying around, the villages were almost entirely deserted and most of the houses had fallen down. The few survivors were desperately trying to find food. An epidemic of violent diarrhea had broken out, thought to have been caused by volcanic ash contaminating the drinking water, and had caused many deaths” (Cavendish "The Eruption Of Mount Tambora"). What was left of the island were nothing but empty fields of the remains of bodies, houses, crops, and even pools of water caused by tsunamis. That’s right tsunamis hit the coast of many islands around the volcano. This was mainly due to the tectonic plates that were moved in the ocean crust. When the volcano erupted it even managed to move tectonic plates underneath it, and since the volcano was right next to the ocean water the tectonic plates clashed with each other creating multiple tidal waves. Despite all this there was another effect the volcano caused to Indonesia, there was an economical downfall. The eruption
Not only did it affect us but also Mother Nature, there was many landscapes that were destroyed and many earthquakes cause by the tectonic plates that will scar the earth forever. Mount Tambora is still recorded in history as the most powerful volcano in years, and it was the only volcano that had a worldwide effect. What makes even scarier is that after this eruption happened many thought it wouldn’t have another eruption for years to come, but in 1967 another eruption happened. Even today the volcano is still active and it can explode at anytime. Who knows if the next eruption is as punishing as the last one, or maybe even far
On May 18th, 1980, one of the most prominent volcanic eruptions in US History took place in the state of Washington. Mount St. Helens had been dormant for almost 100 years before March 15th. On this day, two months before the eruption several small earthquakes shook the earth. This indicated a magma buildup below the surface, and the first minor event that would lead to one of the greatest eruptions the US has ever known. Following the first set of earthquakes, “Steam explosions blasted a 60- to 75-m (200- to 250-ft) wide crater through the volcano 's summit ice cap and covered the snow-clad southeast sector with dark ash. Within a week the crater had grown to about 400 m (1,300 ft) in diameter and two giant crack systems crossed the entire summit area. Eruptions occurred on average from
On May 22, 1915, an explosive eruption at Lassen Peak devastated nearby areas and rained volcanic ash farther 200 miles to the east! This explosion was the most powerful in a series of eruptions from 1914 through 1917. ...
Hidden underneath the park, powerful volcanic, magnetic, and hydrothermal forces are reforming the land. Several earthquakes, uplifting, and subsidence of the landscape proves that these powers exist. Recent studies have caused scientists to think that Yellowstone could be growing larger as flowing molten rock builds up below the ground. In a period of 10 years, the volcano has risen 5 inches, not a significantly detectable difference, but it may have split the ground in the Norris Geyser Bassin that could reawaken some of the geysers, like the Steamboat. In spite of this newly found information, scientists do not speculate the volcano erupting any time soon, but with time, it will end with a super natural disaster, destroying everything in its path
Mount Tambora, located on the Island of Sumbawa, Indonesia is classified as a Stratovolcano. Also known as a composite volcano, Tambora is a tall conical volcano (cone like structure) where layers of the walls are built by hardened lava and volcanic ash. The term composite is used to describe the volcano due to the composite layered structure built from sequential outpourings of eruptive materials1. Among the most common types of volcanoes, Tambora also shares its destructive prowess with best-known volcanoes such as Krakota (1883) and Vesuvius (79 A.D). The Island of Sumbawa is located in the middle of the Lesser Sunda Islands chain (a group of islands in the southern Maritime Southeast Asia) and is in the province of West Nusa Tenggara3. A map of Mount Tambora is shown in Figure 1 to provide a better perspective of its location. Interestingly enough, Tambora forms its own peninsula on Sumbawa, known as the Sanggar Peninsula. In April of 1815, after years of dormancy, Mount Tambora erupted with great intensity, approximately 7 on the volcanic explosivity index, which is shown in Figure 2. It has been estimated that the eject volume of Tambora was 160 cubic kilometres, which represents the largest volcanic eruption in recorded history. The death toll has been projected to be at least 71,000 people, of who over 15% were killed directly from the eruption1. The remaining 75% have been thought to succumb to starvation and disease, as the eruptive fallout decimated the agricultural industry in the region. Following the eruption, a volcanic winter ensued. As sun become less abundant due to clouds of ash, crops and livestock perished. Please note that all definitions appearing in the footnotes are either taken from already referenced so...
Boom! A once ice-capped mountain peak explodes as ash fills the air. “‘Vancouver, Vancouver, this is it!’”Those were the last words of expert geologist David Johnston (Gunn 561). In 1980, Mount Saint Helens of the state of Washington erupted, filling the air with ash and causing mudflows powerful enough to lift tons. It decimated everything in its path. The eruptions, mudflows, and ash caused great damage on the landscape, yet it gave us information on how catastrophes happen and how they affect society and the surrounding landscape. The data acquired can also help us understand the way the landscape was formed. Mount Saint Helens caused much damage, but also helped people understand the science behind it.
Volcanoes have always been a mysterious wonder of the world. Volcanoes have shaped the landscape and the very ground that we all live on. People have written stories of their disastrous eruptions, and painted their marvelous shapes on canvas. The essay will outline some of the more famous volcanoes and how they have impacted are history. Mount Vesuvius that destroy the great city of Pompeii, Krakatoa they spewed deadly ash on small village town, and Mount St. Helen, the only volcano in my own country to every erupt during my own time period.
The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.
From modern examples and records we know that volcanic activity can set of a chai...
These differences are in the makeup of the volcano, the impact on society, and the eruption itself. Mount Saint Helens, used to be a wonder of the world, but now a damage site of what happened on May 18, 1980. Mauna Loa is a tourist destination and one of the most active dispensers of lava and magma in the world. As shown, these volcanoes can’t be more different. Yet, each volcano has been a culprit to destruction, and have similarities within themselves. This report has expressed many similarities and differences and brought facts and knowledge to the historical eruptions by these impressive and ancient structures of
There are forty-two volcanoes in Mexico. Mexico’s volcanoes are on the North American Continental tectonic plate. Out of all the volcanoes the three most active are Popocatepetl, El Chichon, and Colima. El Chichon had its last eruption in 1982. No one living near this mountain saw it coming because its last eruption was one hundred and thirty years earlier and was minor. They also ignored the earthquake on the night of March twenty-eighth. But in the morning no one could miss the ash and debris in the air. Most of the two thousand people that died, died from breathing in the harmful gases. It cooled the whole earth the following year. When it erupted in 1982 it created a three hundred meter deep crater. Before the eruption in 1982 El Chichon

It is known however that lying underneath one of America's areas of great natural beauty, Yellowstone Park, lays one of the largest super volcanoes in the world. Scientists have discovered that it has been on a regular eruption cycle of 600,000 years. The last eruption was 640,000 years ago, therefore this shows the next eruption is late and could erupt at any moment. Scientists know that the collision of a Yellowstone eruption is terrifying to understand.
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
The earthquake with magnitude 9.0 and tsunami hit many regions of Japan and destroyed everything on its ways. The effects could feel over the world. Tsunamis hit Pacific coastal lines in many countries. Numerous people died, missing, or homeless. People lived in shelter, without clean water, power, telecommunication, etc. Japan is still recovering from the damages with the help of foreign relief. Radioactive from the meltdown and the aftermath debris affects the global environment. Learning the mega-thrust earthquake will help us improves the warning system that could save people and avoid serious
When a volcano erupts, the focus is particularly on the consequences that take place near the volcano, such as weather conditions, the impact on nature, and the people who are affected. The noticeable changes that take place after a volcanic eruption includes the decrease in the temperature, natural disasters, such as tsunamis, droughts, and hurricanes, and the air pollution, which can be harmful to plants, animals, and people.
