This may not be the biggest volcano but this volcano changed history with its biggest eruption in history in the 19th Century. This volcano is Mount Tambora, Mount tambora with its biggest eruption in 1815 April 5. Since that day there has been smaller eruptions its now 9,354 ft high it lost some of the top from the eruption in 1815 April 5. Before everything happened Mount
Tambora was 14,000ft high. Also, when the eruption ended, a caldera was 3.7 miles, Mount Tambora third top of the Mountain was destroyed completely.
The danger began April 5 causing small earthquakes and pyroclastic flow but major damage. Pyroclastic flow is fragment of hot rocks, the left overs of other rocks. In that process there is hot gases trapped air inside that moves very fast. Which makes thich gray to black clouds, the temperature is 600 to 700 c (1,100 to 1,300 F). In the evening the day the tragedy happen before the eruption ever happened there was a tsunami of pyroclastic flow

I didn't give up. I liked every part of the project expect doing things wrong. Knowing this was the biggest eruption its amazing but also dangerous All the people that died during the eruption mostly when the island has a lot of volcanoes around the area. It's a very dangerous place but it's so interesting. It was also very tall and so much to know. But the fun part was when i got to build the volcano with my amazing partner and we had so much fun it was challenging mostly when we have to shape it a certain way. Just thinking about it makes me smile working hard and people who acknowledge your amazing work that you work so hard to get too just makes you want to jump in excitement and keep on doing what you like doing. It's a motivation for you can keep on
In March 18, 1880 Mount St. Helens there was a catastrophic eruption that caused a huge volume of ash; the ash plume would be over central Colorado within 16 hours. After years of dedicated monitoring (knowing where to volcano is, unlike an earthquake not knowing exactly where this geological even is exactly) there was been increasing accuracy in forecasting eruptions.
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. ...
The last eruption that occurred was in 1707, and was named the Great Hoei Eruption. This particular eruption followed itself weeks after the Great Hoei Earthquake and measured 8.7 on the Richter scale. This eruption and earthquake severely damaged the city of surrounding areas such as Osaka and Edo (contempor...
...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.
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.
It has a strombolian eruption style but hasn’t erupted in this century. Another massive volcano in Mexico called Iztaccihuatl is located right next to Popocatepetl. Iztaccihuatl is the third highest mountain in Mexico and is a stratovolcano. It’s nickname woman in the white comes from it looking like a sleeping woman when looking from the valley in Mexico. The last earthquake nearby Iztaccihuatl was on July twenty-seventh two thousand and fifteen. The last time this volcano erupted is unknown but they predict it was less than eleven thousand years ago. Paricutin is a volcano that grew right on top of a cornfield and was witnessed by the farmer. This volcano has a strombolian eruption style which means it has many different explosions that shoot a few meters into the air. This volcano is located in west central Mexico and is currently dormant. It consist of cinder cones that have been active but are not currently. The Tacana volcano is on the Mexico Guatemala border. It’s a stratovolcano that stand four thousand and sixty meters tall. Tacana is currently dormant but last erupted in nineteen eighty-six. When it erupted it spit out some ash which killed some plants but otherwise cause no
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.
The eruption on Mount Saint Helens has a specific cause and comes with many effects. A multifold of people would say that the “mountain looked like the site of an atomic blast” (Bredeson 30). That is a very accurate depiction as it took great power to inflict as much damage as it did. The reason for this impressive amount of force is that when magma is built up with pressure and an earthquake hits, the pressure gets magnified and the volcano explodes (Lewis). This is exactly what happened inside Mount Saint Helens. Furthermore, it has been revealed that “The earthquake that triggered the explosion was a 5.2 on the Richter scale” (Gunn 559). The earthquake to the magma can be compared as a match to gasoline. Even though the earthquake was not huge, the scale of the eruption was much greater than that of the earthquake (Gunn 560). The earthquake was only the trigger that allowed for more devastating things to occur. Thirteen hundred feet of the volcano were lost in the explosion followed by landslides, mudslides, and lava flows...
57 people were killed, and 200 homes, 47 bridges, 15 miles (24 km) of railways and 185 miles (300 km) of highway were destroyed. The eruption blew the top of the mountain off, reducing its summit from 9,677 feet to 8,364 feet in elevation and replacing it with a mile-wide horeshoe-shaped crater. Like most of the other volcanoes in the Cascade Range, St. Helens is a great cone of rubble, consisting of lava rock interlayered with ash, pumice and other deposits. Volcanic cones of this internal structure are called composite cones or stratovolcanoes. Mount St. Helens includes layers of basalt and andesite through which several domes of dacite lava have erupted.
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
Mt. Ontake's eruption was the worst disaster in 90 years. Ash covered towns, houses, people being buried alive, and knocked out by flying rocks. Causing an estimated 2 million dollars of damage. As if that was not enough, there were earthquakes with a 2-3 on the Richter scale, causing more damage. Killing more people and causing buildings to crumple, as if, made of straw.
The history of volcanic activity at Yellowstone starts with its first eruption at Huckleberry Ridge 2.1 million years ago, the leftovers reached as far as Iowa and central Texas. Then 800,000 years later, another eruption took place in Mesa Falls creating Henry Fork Caldera near Park, Montana. The last eruption took place 630,000 years ago, called the Lava Creek eruption, spewing 240 cubic miles of debris, and spreading as far as Louisiana and California.
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
The Mauna Loa volcano is located in Hawaii and means "Long Mountain" in Hawaiian. It is a giant, basaltic shield volcano. It is one of the largest volcanoes and mountains in the world and has been called the "monarch of mountains". It has an estimated volume of 9,600 cubic miles and takes up half the land of Hawaii. It extends about 120 km starting from the southern tip of the island to the northern region. It is 97 km (60 miles) long, 48 km (30 miles) wide, and is 8,742 km (28,680 miles) high from the base on the sea floor to the top. The slopes are steeper than 12 degrees and about 4 degrees at the top of the volcano. Mauna Loa formed about half a million years ago and in the middle stages of forming into a shield volcano where lava flows to form a sloped and broad flat domed volcanic cone. Along with Mauna Kea, the Mauna Loa volcano is responsible for the creation of the Hawaiian Islands. Mauna Loa has erupted thirty-three times since 1843 and is known as one of the most active volcanoes in the world today. The last eruption was 1984 and lava flowed within 4 miles of the city of Hilo. This shows that it is dangerous to live anywhere near Mauna Loa and that it poses as a threat to anyone living near it because it has a very high possibility of erupting within a very short span of time. Below is a picture of Mauna Loa taken from a bird's eye view.
Firstly, I believe the eruption of Santorini was more powerful than first estimated, due to the presence of a shallow sea inside the Theran crater, with the volcano situated in the centre of that sea. (This is the theory of Professor Steve Sparks of Bristol University)
