Supervolcano Facts

You may think that a supervolcano is far out of our reach and it could be thousands of years before one erupts and causes havoc all across the world, conversely it is not as far away as you may be thinking. A supervolcano refers to a volcano being able to spew more than two hundred and forty cubic miles of magma. Volcanoes causing this much destruction are not uncommon and there have been five volcanoes to erupt and wipe out massive amounts of life. Five may not seem like a massive number, but what came about during these eruptions and after the fact is what makes the event a terrifying reality. Around two hundred and forty eight million years ago the Permian-Triassic extinction destroyed ninety to ninety five percent of all species on Earth due to a massive volcano, other instances include The Laki Volcano in 1783 and

In recorded history, there have been 151 earthquakes in Nevada that were a magnitude of 3.5 or higher. As previously mentioned, the mountain ranges of Nevada are typically bound on one side or the other by a fault. There are quaternary faults that range in ages from less than 150 years to around 1.8 million years in existence. The property damage in Nevada from earthquakes was .2 million dollars between 1196 and 2014 based on information from department of energy for the state. As we studied in our textbook, earthquakes can by a number of things, such as shifting faults, or volcanic

The Geyser Old Faithful in Yellowstone National Park, U.S.A. is a geyser that has a relatively isolated source of seismic noise. The seismic behavior of this one geyser is similar to many volcanoes observed.

Yellowstone is a beautiful park, but a long journey to go through. The park had been explored by many people and is widely known. A couple of the people that have traveled through Yellowstone National Park are, John Colter and Tom Murphy. These two men went through difficult struggles to get through the park.

The Yellowstone volcano is very active volcanic system which requires much observation. The geysers, mudd pots, hotsprings and steam vents are all examples of the heat from molten rock of a volcano. For many years the Yellowstone volcano could not be located. There is not obvious signs of a volcano, but scientists looked for other clues. Rhyolite is present in a location that has pinetress and many mosquitoes can be found due to the lakes that have formed. Rhyolite is a very violent eruption, due to the high silica content,  it flows slowly, like honey, and tends to pile up and form lava

In contrast, Yellowstone was formed when a hotspot moved under it and over millions of years has caused eruptions which have shaped present day Yellowstone.

Albeit no emissions of magma or volcanic cinder have happened for some a large number of years, future ejections are likely. In the following few hundred years, risks will most likely be restricted to continuous fountain and hot-spring action, incidental steam blasts, and moderate to vast quakes. To better comprehend Yellowstone's well of lava and quake risks and to help ensure people in general, the U.s. Geographical Survey, the University of Utah, and Yellowstone National Park structured the Yellowstone Volcano Observatory, which persistently screens movement in the

The Yellowstone is known as one of six largest supervolcanoes in the world. Though this supervolcano has not erupted recently it does have continue to have volcanic activities. The previous eruption remains have been found outside of the Yellowstone National Park that link to the Yellowstone Caldera. Ben Ellis and Mark Darren, authors of the article “‘Super-eruptions’ and silicic volcanism from the Yellowstone volcanic field,” describes current volcanic activities of this area and how it has expanded and transition from its previous super-eruptions to what has happen now, and what changes could another volcanic reaction cause for this area. Ellis and Darren wrote that the “. . . evidence of volcanic activity is all around” (135). In this they were talking about Yellowstone.

There is an assortment of geologic activity at Yellowstone and Hawaii. At Yellowstone there are 1,000-3,000 earthquakes per year at Yellowstone. There are also over 10,000 thermal features found in Yellowstone (Volcano Questions & Answers). In Hawaii Mauna Loa and Kilauea are regarded as active volcanoes. Mauna Loa last erupted in 1984 and scientist predict this volcano will erupt again in the future. Kilauea is the world most active volcano and has been continuously erupting since 1983

Yellowstone National Park forms the core of the Greater Yellowstone Ecosystem. Sitting on 34,375 square miles, it is considered one of the largest nearly intact temperate-zone ecosystems on Earth (Schullery). Greater Yellowstone’s diversity and natural wealth includes the hydrothermal features, wildlife, vegetation, lakes, and geologic wonders like the Grand Canyon of the Yellowstone River (Hydrothermal vents and how they work). Yellowstone National Park was established in 1872 primarily to protect geothermal areas that contain about half the world’s active geysers (Hydrothermal vents and how they work). During that time, the parks natural state was largely taken for granted. As development throughout the West increased, the park’s over 2 million

According to our textbook, it appears that an earthquake poses a greater threat to the Pacific Northwest than a volcano does. The text states that “California’s San Andreas Fault runs diagonally from southeast to northwest for nearly 800 miles.” In the lecture notes, it shows a diagram of the earthquakes that have occurred since 1977 along the Pacific coast, and the area is riddled with earthquakes. The likelihood of a massive scale earthquake occurring in the Pacific Northwest has been predicted; however, our lecture states that we are unable to predict an earthquake and are only able to gauge the probability of one occurring. Those who would be in harm’s way would be those people who fall within the Mercalli Intensity scale area, and those

The third eruption happened about 640,000 years ago, and spewed 240 cubic miles of material. This third eruption created the third and largest of Yellowstone’s calderas, Yellowstone Caldera, which is 30 by 45 miles in size. The pyroclastic lava flows from this eruption formed the north wall of the caldera and are visible from the south-facing cliffs east of Madison. (Solcomhouse) This third eruption is said to have vaporized an entire mountain range. Smaller eruptions have also helped to shape Today’s Yellowstone, such as one that occurred 174,000 years ago and created what is now the “West Thumb” of Yellowstone Lake. (National Park Service) Many sources say that a catastrophic eruption, such as those that have formed the three calderas at Yellowstone, is unlikely during the next several hundred years, but if one such eruption did occur it would devastate much of the United States and would have the potential to alter the global climate.

Fifteen-year-old Alex is home alone when the supervolcano erupts. His town collapses into a nightmare of darkness, ash, and violence, forcing him to leave, and as fast as he can. When an escaped convict injures Alex, he searches for a sheltered place where he can wait - to heal or to die. Instead, he finds Darla. Together, they fight to achieve a nearly impossible goal: surviving the supervolcano. The real question is, is this survival of the fittest or just

Volcanoes and Earthquakes are two of the most intriguing natural disasters that can occur on earth. Unlike hurricanes and tornadoes, they can awaken at almost any point in time throughout the year. These two natural disasters are also different from others because they occur on the layers of the earth itself. Volcanoes, while large to us, are actually small, conical patches of earth that spurt and ooze hot molten lava from the core, and can destroy areas of land triple their size. Earthquakes, on the other hand, are severe jolts felt on land due to the movement of earths tectonic plates. Some may describe earthquakes as being similar to riding a bike down a flight of stairs. The impact of an earthquakes can take down even the largest buildings and strongest structures. All natural disasters can have damaging effects on land, some more than others, and all can be measured or predicted in different ways. Although earthquakes and volcanoes are similar to each other, the two are still very comparable. A few of these similarities and differences include the cause of their occurrence, and how their occurrence impacts the environment.
