The biggest volcanic eruption ever recorded by humans was the eruption of Mount Tambora on Sumbawa Island, Indonesia, in 1815 (livescience.com, pg. 1). It ranked “super colossal” on the Volcanic Explosivity Index, the second highest rating. The eruption resulted in a brief period of significant climate change that led to cases of extreme weather. Volcanoes can cause great devastation and harm to people, animals, environments. For instance, fast-moving lava, lahars, and other effects after an eruption can kill people and damage property on it’s way down. Above all, volcanic eruptions can even cause long term effects on the climate by making the world colder.
In 1985, a volcano named “Nevado del Ruiz” killed over 20,000 people in Tolima, Colombia.

During the eruption, commonly known as the Armero Tragedy, four volcanically induced mudslides barreled down the mountain at 30 miles per hour, making it next to impossible for anyone to get through without getting stuck (en.wikipedia.org, and geology.sdsu.edu). By the time the relief workers got to the city, over 12 hours after the initial eruption, many people with serious injuries were already dead. This was titled the fourth deadliest volcanic event ever recorded since 1400 AD, and the second deadliest in the 20th century, right behind the 1902 disaster of Mount Pelée, which killed about 30,000 people on the island of Martinique in France (en.wikipedia.com, and geology.sdsu.edu). A child named Omayra Sánchez quickly gained popularity after a photo was taken of her stuck in rubble by Frank Fournier. She died after 60 hours, probably as a result of gangrene or hypothermia, as she was stuck in water and mud (en.wikipedia.com, and news.bbc.co.uk). The deaths are thought of as the fault of the Colombian government, who ignored the suggestions by scientists to evacuate the city months before the eruption. Although volcanoes can cause enormous mudslides, there are other effects a volcano eruption can cause. According to the Hawaiian Volcano Observatory, a volcano named “Kilauea” produces enough lava in 15 seconds to fill up the gas tanks of about 1,000 SUVs (hvo.wr.usgs.gov).
Although Kilauea is a medium to small sized volcano, the Observatory says that it has been releasing lava for the past 24 years. The Observatory also said that “Kilauea has been releasing more than twice the amount of noxious sulfur dioxide gas (SO2) as the single dirtiest power plant on the U.S. mainland”. Some of the particles of dust and ash released into the air are so light that they can stay in the stratosphere for months and travel (sometimes worldwide), blocking sunlight and causing cooling over large areas (scied.ucar.edu, paragraph 5). But, the sulfur dioxide let into the air by an eruption does a much better job of cooling climates. It goes into the stratosphere, combines with water to form sulfuric acid aerosols. It then makes a “haze of tiny droplets in the stratosphere that reflects incoming solar radiation, causing cooling of the Earth’s surface.” (scied.ucar.edu, paragraph 6). The aerosols can stay in the stratosphere for up to three years, causing significant cooling wherever the wind moves it. The highest estimate of global volcanic emission, .26, is way less than the estimate of human emitted CO2 in 2010, which is 33.6 (volcanoes.usgs.gov). Although humans produce more CO2 than volcanoes do, there has been times where volcanic eruptions have caused temporary below-average temperatures,
permanent climate change, and added to global warming. Volcanoes can affect the environment in negative ways, but that’s not to say they’re completely bad. They provide a beautiful landscape and make the ground surrounding the volcano incredibly fertile. But, they’re still not safe to be around without correct evacuation routes and close monitoring by the government.
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. ...
What is a super volcano, what is a volcano? A volcano itself is a hill or mountain with vents to the crusts of the earth that let magma sit under or in the mountain. “A super volcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1,000 km3 (240 cu mi). This is thousands of times larger than normal volcanic eruptions. Super volcanos are on a much bigger scale than other volcanoes. Unlike composite volcanoes, with their steep sides, they are difficult to spot.” (Internet Geography, geography.learnontheinternet.co.uk) An average volcano in the world would just cause local damage, but this super volcano could end life on earth. Not just with the eruption but the ash would cause a volcanic winter blocking the sun to long and then even more the ash would choke everything out and collapse roofs. Yea Rainier would kill thousands of people, but Yellowstone would literally kill billions plus of people. In comparison, Rainier is a little fly and Yellowstone is a Griffin {The big eagle lion bird thing}. Yellowstone has the capability to erupt 1,000 times stronger than Rainier ever could.
...815 eruption of Mount Tambora. With over 70,000 deaths and a rating of 7 on the volcanic exclusivity index, this eruption is one of the largest in recorded history. Not only did this volcano cause destruction in Indonesia but the consequences were further felt around the world, as volcanic ash and sulphuric gases were dumped into the stratosphere causing a global climate shift. Dark clouds covered the sun, and dramatic weather changes ensued. Flash floods frequently occurred wiping out a great deal of crop eventually causing prices to skyrocket. Disease began to spread due to malnourishment and unsanitary living conditions. Eventually these consequences subsided and citizens began to migrate towards Mount Tambora once again. Today the government has placed seismic sensors are set up in the most volatile areas to ensure preparedness in the event of another volcano.
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
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
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.
Over 50 people were killed when the volcano in central Japan erupted without warning on 27 September, the country’s deadliest volcano eruption since World War II. Several hundred people were thought to have been on the mountain when it erupted at 11.52am.
In Allende’s story a horrific volcano eruption has happened thus resulting in hundreds of thousands of people dead by being trapped in the mudslide. In Allende’s story history is an important factor since Allende wrote her story based on the story of Omayra Sanchez from the 1985 Colombia’s Nevado Ruiz volcanic eruption. Allende changed the characters names and although the date is not specified, it is understood from Allende’s other Stories about Eva Luna that it takes place sometime during the 1980s which would be around the same time as Omayra Sanchez’s story. Allende uses her writing platform to shed some light on how impactful stories
El Salvador, 6 April 1992--Three siblings died near the Guazapa volcano last weekend when they stepped on a mine planted during the period of civil warfare. Ironically, their parents had returned to the area only a few days earlier. The children were four, six and eight years old. Parts from the three children's bodies were found as far as 30 metres from the explosion site. (qtd. in Grant 25)
When the reservoir has formed, a substance is collected that will trap the volcanic gases. They form depressions in the ground and it is very hard to imagine the eruptions, explosions, car atrophic proportions that they cause. Super volcanoes produce vast amounts of ash and destruction. There are thousands of normal volcanoes around the world and at least 50 erupt every year. Vast clouds of ash are deafening sounds; it affects the climate on earth for many years and affects the agriculture colour.
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
Volcanoes are magnificent and powerful land features. The magma erupts from the Earth forming islands, cooling to form rocks, and changing the landscape on eruption at a time. They can erupt at any time! Since volcanoes are dangerous we have developed technology to detect these impressive explosions. Since Hawaii was formed by a volcano when you visit Hawaii you are standing on cooled lava! There are 3 different stages a volcano can be in and 2 very different types of explosions that can happen. Volcanoes are magnificent and have beautiful features.
Living in close proximity to a volcano when erupted can cause a large number of things to happen to human health. Smoke Inhalation which can cause suffocation. Fast magma flow, and mudslides are also a hazard. Even living quite some distance from an active volcano can be a hazard. Take for example in 1815 the eruption
Molten rocks pouring from faults in the earth’s surface causing massive shivers in the crust and deadly clouds in the sky. Volcanoes cause a lot of damage both to our environment and to ourselves. The damage one eruption causes is massive. Volcanoes don’t erupt very often on land, but in the water there are thousands that explode every year. These underwater eruptions can sometimes grow so big they break the surface of the water and create islands like Hawaii. The clouds of ash created through these eruptions start out deadly and can overload your lungs but after they have settled they create extremely fertile soil.
Preventing volcanoes from creating damage is not a lot. Living near a volcano has greater consequences, rather than living far from a volcano. volcanoes can and had create a massive amount of disaster. The molten lava that erupts from a volcano, can spread through the land and destroy everything in its path. Another effect is that the smoke that comes out of a volcano can affect the people’s health.
