While our Earth has formed from many different things, volcanic eruptions have been a huge part of that. The most infamous volcano eruptions either did something to impact the planet or region they were part of in some way. This could be that they helped to form something we see today or that they ended many human lives as well as plants and animals. Some places have been impacted by the local volcano so much that entire craters were formed from eruptions. Others made the Earth move so much that they helped to lead to some of the continents we see today.<\/p>\n
It is clear that major volcano eruptions led to rises in heat and even led to the lowering of temperatures too. In fact, many believe if there is going to be an extinction event in our lifetime, it’ll likely be due to nuclear weapons or a major volcanic eruption. With that said, we wanted to discuss some of the biggest in history. Before we do that, there are two big things we will be using. First, we’ll be using the Volcanic Explosivity Index (VEI)<\/a><\/strong>, which rates volcanos from the low 0 to the highest level of 8. Second, we’ll also be using the BCE and CE history system rather than the B.C. and AD system. All that said, let’s get started!<\/p>\n
The Mount Fisher volcano formed a very long time ago on Unimak Island in the Aleutian Islands of Alaska. This volcano formed from a destructive eruption of an andesitic stratovolcano (volcano with many layers) a little over 9,000 years ago. When this took place, the Fisher Caldera formed out of it. What exactly is a caldera formation?<\/a><\/strong> Calderas occur when a large depression is formed from a volcanic eruption or collapse. When this happens, magma within the magma chamber under the volcano will be expelled with tremendous force. As this magma chamber empties, any support magma within will also disappear.<\/p>\n

The Mauna Loa<\/a><\/strong> volcano is one of the five major volcanoes on the Island of Hawaii inside the U.S. state of Hawaiʻi. It is considered the largest subaerial volcano in terms of mass and volume on the planet. This is a volcano type that usually sees a chunk of its body below water. In fact, one could have made a case for it being the largest volcano on Earth full stop, but Tamu Massif beats it out there. Although, the volume of this volcano measures 18,000 cubic miles. However, the peak is only about 125 feet lower than Mauna Kea’s nearby.<\/p>\n

The Santa Maria Volcano<\/a><\/strong> gave us our very first major volcanic eruption in the 20th century. The Guatemalan volcano erupted on its southern side with a massive explosion that left a crater measuring out to roughly one mile in width on the side of the mountain. Before 1902’s eruption, no one really even worried about the Santa Maria volcano because it had not erupted in hundreds of years. In fact, it had been dormant for around 500 years by this point. The fact that it erupted at a level 6 on the Volcanic Explosivity Index out of nowhere likely made these Guatemalans assume the end was near.<\/p>\n

On February 16, 1600, Southern Peru was shaken by one of the most massive volcano eruptions in history. In fact, it was such a huge eruption that many claim this volcano eruption helped to create the Little Ice Age. Although, it was not solely responsible for this. While Huaynaputina has erupted several times, it was this eruption in 1600 CE that did more damage than any other eruption from this volcano. In fact, it is still the largest volcano eruption ever recorded in South America. People in the city of Arequipa witnessed the eruption as it happened but it is possible none of them truly knew how much harm this volcano would cause.<\/p>\n

The Mount Yasur Volcano<\/a><\/strong> can be found on the Tanna Island of the Republic of Vanuatu, found in the South Pacific Ocean. The volcano stands 1,184 feet high above sea level. It’s a largely unvegetated pyroclastic cone with a beautiful circular crater at the summit that measures out to 400 meters in diameter. Another stratovolcano, Mount Yasur was actually formed when the Indo-Australian plate moved eastward while being subducted under the westward-moving Pacific Plate. Since its formation, it has erupted many times. Today we know it has been erupting constantly since around 1774 CE, the longest constant eruption cycle in history.<\/p>\n

New Zealand is a beautiful nation that seems to have every possible environmental interest one could have from nice warm areas for fun in the ocean to snow-filled mountains. It should not shock anyone to find out a volcano exists here, right? Sadly, the locals were very unhappy any existed on June 10, 1886, when Mount Tarawera<\/a><\/strong> erupted. The Level 5 eruption formed fissures in the Earth that actually extended up to 10 miles from the epicenter of the volcano. You could hear the blast up to 310 miles away from the territory. Talk about one of the loudest volcano eruptions ever, right?<\/p>\n
<\/p>\n
The Kelud Volcano<\/a><\/strong> is one of the most active volcanoes in the world, presenting some of the worst volcano eruptions in history. Its eruptions are not as energetic as some of the most infamous eruptions listed here. However, they happen all the time and result in deadly mudflows. This seems to occur so often due to the massive amount of water in the crater of the volcano. In fact, many believe the eruption in 1586 was likely so terrible because of this factor.<\/p>\n

The name of this volcano may seem odd to some, and rightfully so. However, it was named after a 20th-century U.S. Army General who was considered to be the father of the modern-day U.S. Air Force. The volcano is part of the island of Bougainville, found northeast of the official Bagana Volcano in Papua New Guinea. It is officially classified as a “pyroclastic shield volcano<\/a><\/strong>.” These are uncommon shield volcanoes that are formed mostly out of pyroclastic and high explosive eruptions, rather than simply being made of fluid basaltic lava. Most have a central caldera with low-angle flank slopes.<\/p>\n
<\/p>\n
The Cotopaxi Volcano<\/a><\/strong> can be found in the Andes Mountains, within the Latacunga city of the Cotopaxi Province. While this Ecuadorian city is not well-known, the volcano has made the territory quite popular for scientists. The volcano is the second highest summit in Ecuador, standing at 19,347 feet. While its height makes it pretty cool, what makes the volcano legendary is that it happens to be among the most active volcanoes in the world. As of this writing, it has not erupted since January 2016 after starting its eruption in August 2015.<\/p>\n

Most people do not venture to Antarctica, but those who do might come across a place known as Deception Island<\/a><\/strong>. The name is quite apropos, as it looks like a relatively nice place in a winter wasteland. Yet underneath all of this, you’ll find the caldera of an active volcano that made the name of this place make so much more sense. Antarctica is still so misunderstood, so scientists from all over the world have been going here to study the continent as best they could. On top of this, hunters who used to hunt whales in the region made several different settlements in the territory.<\/p>\n

Very little is made of Chinese volcanos, but volcano eruptions happen here just as they do in other large territories. The Baitoushan Volcano here was one of the most powerful in history. In fact, it erupted so powerfully that ash and debris landed as far away as Japan, roughly 750 miles from the volcano. The blast created a caldera that stretches three miles wide and is about a half-mile deep. Today, Lake Tianchi<\/a><\/strong> or Sky Lake is present in this crater. The lake is a major tourist destination, as the Chinese government managed to beautify the territory many years after its chaotic eruption.<\/p>\n

While El Salvador might not be considered a major hotspot for the Mayan Civilization today, it was going to be. Yet when Mount Ilopango<\/a><\/strong> erupted between 430 and 450 CE, it destroyed entire Mayan cities in the region and resulted in the civilization moving closer to Guatemala. This major eruption ended up creating a major caldera that houses Lake Ilopango today. At the time, it is said that the ash-cloud fallout from the eruption would have blanketed at least 3,800 square miles in roughly waist-deep pumice and ash. Agriculture in the territory would have been nonexistent for decades.<\/p>\n

When Johnny Cash sang about a “ring of fire,” did you assume he just grabbed this out of thin air? Oh no, the ring of fire is technically a real thing. It is found in Alaska (among other areas), and it was formed thanks to the volcanoes in the region. One of which is Novarupta, which actually formed in 1912. That makes it likely the youngest volcano on this list. The eruption that led to Novarupta<\/a><\/strong> forming was massive and reached a level 6 on the VEI scale. The violent eruptions began on June 6, 1912, and would last for 60 hours before stopping. By the time it did, roughly 3.1 to 3.6 cubic miles of ash were expelled in the region.<\/p>\n

Mount Thera managed to do something that very few other volcanoes can claim. This volcano, located on the island of Thera in the Aegean Islands was essentially world-changing. This was a major event in human history<\/a><\/strong> that wiped out the Minoan civilization that lived on the island of Thera. Geologists now believe it was likely the strongest explosion that was ever personally witnessed by a human. Thera erupted with the measured energy of several hundreds of atomic bombs in just a fraction of a second.<\/p>\n

These Alaskan volcanoes are something else. The Semisopochnoi Island feels like a place you’d see after a nuclear explosion wiped out life on the planet. It is uninhabited and does not contain ANY mammals. This works out well for many maritime birds that utilize the place for nesting as a result. The island is actually home to several volcanoes, including Mount Cerberus<\/a><\/strong>. The main volcano, the Semisopochnoi, is the largest subaerial volcano in the western Aleutians. It stands at a little over 12 miles wide above sea level while it contains a caldera that measures out at nearly 5 miles in width.<\/p>\n

In the southwest territory of the Pacific Ocean, you’ll find several small islands. Around this territory, you’ll find Ambrym Island which happens to be part of the Republic of Vanuatu. This happens to be the site of a major eruption that took place in 50 BCE. While volcanic eruptions can be powerful, very few are able to create a caldera on an island that is 7.5 miles wide. Upon erupting, volcanic ash and debris were sent for thousands of miles. The eruption, to the shock of no one, was rated a 6 under the Volcanic Explosivity Index. What might freak you out more is that this very same basaltic volcano is still active to this day!<\/p>\n

The Eyjafjallajökull volcano<\/a><\/strong>, located in Iceland, happens to be one of the few major volcano eruptions to occur in our lifetime. The eruptions here lasted for about 6 days starting on April 14th while localized disruption continued into May 2010. However, eruptive activity STILL kept going until June 2010. Finally, after another three months of activity, the eruptions were finally over in October 2010. From April 14th to the 20th, ash from the eruption covered large areas of Northern Europe. All in all, around 20 countries were affected so badly by it that they had to close off air travel to commercial flights.<\/p>\n

Mount Mazama<\/a><\/strong> is considered a complex volcano, which consists of volcanic centers and has a mixed landform. They tend to form due to changes in eruptive habits or in the location of the principal vent area of another volcano. Most of these mountains in the Cascade Volcanic Arc formed around 7,700 years ago. The collapse of the volcano formed a caldera that now holds “Crater Lake.” Mount Mazama was originally 12,000 feet but the climactic eruption and subsequent caldera took it down to 8,157 feet. Crater Lake itself is actually 1,943 feet deep. This is the deepest freshwater body source in the United States and the second deepest in North America.<\/p>\n
<\/p>\n
Part of the Central Volcanic Zone in the Andes Mountains, Cerro Blanco<\/a><\/strong> is a volcanic collapse structure located at an altitude of around 15,320 feet within a depression. The caldera itself has been active for at least eight million years, but not consistently. The many eruptions have since created many ignimbrites. While several major eruptions have taken place, one of the biggest occurred around 2300 BCE. It is the largest eruption of the Central Andes, rated at a 7 on the VEI rating scale. It actually formed the most recent caldera in the Cerro Blanco territory, along with some thick ignimbrite laters.<\/p>\n

Yellowstone National Park is absolutely beautiful, but it houses one of the most powerful supervolcanoes on the planet. In fact, an eruption from this volcano would be so significant to the planet that it is classified as a “doomsday event.” What is so interesting is that this volcano erupted in the past but it was long before any present-day humans were around. In fact, the last time it erupted, humans looked very different. The Yellowstone volcano erupted 640,000 years ago and actually made such an impact when it did, that the entire park you see today was shaped by this eruption.<\/p>\n

You can find this amazing stratovolcano on the island of Martinique, which happens to be a French-owned island in the Caribbean. Mount Pelée<\/a><\/strong> is likely what made this island famous, and it is quite a beautiful thing to see. It has several stratified layers of hardened ash and solidified lava that shows its past well. While it has not erupted since 1932, it could erupt at any point. Experts who studied the volcano believe it is still very much active, and should not be overlooked. The last time it was overlooked though, many people died.<\/p>\n
<\/p>\n
The Pago Volcano<\/a><\/strong> in the West New Britain Province of Papua New Guinea is not the most active volcano. As in, it does not erupt a lot. However, when it has…it did so in some of the most horrific ways one could ever see. Funny enough, Pago is relatively young in terms of volcano age but it has made its impression on Papua New Guinea. Several major eruptions took place here, so it is hard to pick just one. It should be known that as of today, the volcano has erupted a total of eight times in 500 years. That includes the major eruption from 1933 that nearly leveled everything.<\/p>\n
