The Supervolcano In Yellowstone Earthquake

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

Also, ground deformation involves the movement of magma within the lithosphere can deform the ground above, this has been witnessed at Yellowstone beneath Yellowstone Lake. This swelling of the volcano signals that magma has collected near the surface. Scientists monitoring an active volcano will often measure the tilt of the slope and track changes in the rate of swelling. Mount St Helens showed this prior to its eruption in 1980. Both magma movement, changes in gas release and hydrothermal activity can lead to thermal emissivity changes at the volcano's surface. We can use satellite imagery, activity of minor extrusive features such as geysers and hot springs and mapping to monitor this. Finally, Remote sensing is the use of satellites to detect things about the Earth’s surface. This is useful for monitoring any changes in volcanoes at the surface. Using satellites we can monitor the thermal activity of the volcano to check for upwelling magma, we can check for escaping Sulphur dioxide using gas sensing and we can look to see if the ground is deforming by checking before and after images of the ground. The satellite can also judge if the ground is being uplifted by measuring the distance between the satellite and the ground.

In conclusion the recent conception and development of plate tectonic theory has greatly aided our understanding of the distribution of seismic events. We now understand that there is a correlation between earthquakes/volcanoes locations and their proximity to a plate boundary plates are continually moving and earthquakes and volcanoes are found along these boundaries. Exceptions to this rule such as Hawaii also help prove tectonic theory due to their unique creation. Whilst this has helped our understanding we also recognise the fact those in LEDCs with poor access to education are unaware of plate tectonic theory so they cannot understand the hazards that some countries face, nor have the means to mitigate against them thus worsening the

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

• This earthquake may not have released all of the strain stored in its rocks next to the fault this reveals a potential earthquake in the Santa Cruz Mountains in the near future. The occurrence of the earthquake showed that the Earth did not exhaust all its strain and hence other earthquakes could be expected. However, the dates could not be predicted. The extent of the damage could have been much more devastating for the region, but with the earthquake occurring near the coast this made half of the felt area westward in the Pacific Ocean. The occurrence of aftershocks ten days later reinforces the unpredictability nature and hence makes Geology to be a study that is always evolving. In conclusion, the Earth and the study of cannot be exhausted as every natural occurrence provides a new puzzle to be solved.

Over more than 50 decades there has been multiple earthquakes that have been caused by the activity that takes place beneath and above the surface of the earth. For every earthquake there are various effects and consequences, these are generally not preventable but teachable moments. As we study and explore landforms we learn and better understand how today 's structures came about, what took place decades ago and where do we go from here. Thanks to the technology and inquiring minds we are able to study past events like the 1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future.

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

Another well-known geological phenomenon in the United States is Yellowstone Park. Yellowstone is an extraordinary example of a caldera which is defined as “a volcanic crater that has a diameter many times that of the vent and is formed by collapse of the central part of a volcano or by explosions of extraordinary violence”(USGS). Since Yellowstone is a caldera, it means that there had been previous volcanic eruptions in this area and in this case two eruptions. The first explosion happened over 2,000,000 years ago because the composition of the magma contained vast traces of explosive matter that caused the eruption (USGS). The second incident happened around

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

Lava flows of rhyolite and basalt have flowed through parts of Yellowstone as recently as 70,000 years ago. These lava flows destroyed everything in their paths while moving slowly at a rate of a few hundred feet per day, flowing months, or sometimes even several years. They are thick and cover as much as 130 square miles. They have nearly filled the Yellowstone Caldera, and spilled beyond the caldera’s border. These lava flows are responsible for forming four of the nine named plateaus in

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

The 1980 Mt. St. Helens explosion revolutionized the scientific study and volcanic monitoring; the devastation brought many geologists to investigate the scientific and hazard assessments of the massive volcano explosion. This explosion became the deadliest catastrophic volcanic event that killed many people and destroyed many communities, which the explosion created a major landslide, directed blast, eruption plume, pyroclastic flows, and lahars (Vallance, Gardner, Scott, Iverson, Pierson, 2010). Vallance, Gardner, Scott, Iverson, and Pierson (2010) point out that the 2.8- cubic- kilometer landslide reduced the summit and the sudden decompression of shallow gaseous magma caused a directed blast that traveled about 500 kilometers per hour

Intense earthquake activity persisted during this time and aerial observations indicated that the earthquakes had induced small avalanches of snow and ice. As early as March 31st, volcanic tremors had begun to be observed on seismographs. Volcanic tremor is a continuous, rhythmic ground shaking that is generally longer in duration and more continuous than that produced by an earthquake of similar amplitude. As a result of these data, scientists believed that a magma eruption from Mount St. Helens was very likely (Mounsthelens.com, 2014). However, no eruptive activity was observed between late April and early May at which time small steam blast eruptions began again. These ceased on May 16th. During this time, the north face of the volcano was becoming distended and cracks were appearing. The "bulge" grew at a rate of about 1.5 metres per day to more than 135m higher than before the magma intrusion. The bulge eventually collapsed and triggered the eruption and subsequent events of May 18, 1980. See Figure 3 for a diagrammatic representation of the sequence of events.

My article is about Yellowstone supervolcano's, for example the article states that ‘’ a supervolcano is not expected to erupt or explode anytime soon if it did , though, the eruption would be powerful enough to blanket the western U.S. with ash’’. Many people have a theory that a mantle plume formed the Yellowstone supervolcano a new computer test shows that this theory was really wrong. ‘’ Leonard thinks the heat source comes from Juan de Fucaridge. It is a volcanic area in the Pacific Ocean. Scientist keep arguing over the information of the Yellowstone. My article also tells me about Lijun Liu a geologist ‘’he built a computer simulation with his student Tiffany Leonard after entering information about Yellowstone into the computer’’

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.
