Exploring The Interaction Between Volcanic And Seismotectonic Processes

A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also

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

A hazard is a situation that poses a level of threat tolife, health, property or environment. The level of hazard posed by different volcanoes can very greatly, from a weak eruption with minimal impact that causes little damage, to a voilent and life threatening explosion. Most of the sixty-plus volcanoes that erupt each year are low risk, however a combination of factors can cause a volcano to be a serious hazard. The factors causing these variations will be explained in this essay.

The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions of these ginates represent a constant risk in the places inhabited by the human being, nevertheless the people ususually live in these areas no matter the risk. On the other hand the volcanos can change the geology of an impressive form, or to cool the temperature of the earth, or to darken the sky. The scientific community increases its efforts to try to understand better what happens in volcanoes, however it is impossible to predict these conditions.

When Krakatoa erupted, scientists were unaware of what was about to happen. Because of Krakatoa’s eruption, we were more prepared for Mount Saint Helens’s explosion. The information from both of these two volcanoes are continually gathered and reviewed for future reference, hoping to prepare us for coming volcanoes. Krakatoa and

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

Something beautiful can also be dangerous, as like the darkness can have phenomenal results. Volcanoes are one example of nature’s beauty, they can be fascinating, exciting, magnificent, but they can also be catastrophic. Their hazard eruptions put many lives at risk, destroying properties, places, and can disrupt air quality. The list of volcanoes is huge, there are three groups of them, dormant, extinct and active volcanoes. From the latter group there are about 500 in the entire world. Although both Mt. St Helens and Mt Pinatubo are two of the most significant volcanoes in the world, they have some characteristics that show their differences and similarities between both of them.

Volcanology – This is another discipline of Geology that studies the Volcanoes and their energy, energy that comes from the heat from inside the Earth and causes eruptions. This studies the volcanoes and its impacts.

Initially, earthquakes shape the Earth’s surface by creating mountains and geysers. In the article “Historic Earthquakes,” it reads, “High intensities were observed in the northwest section of Yellowstone National Park. Here, new geysers erupted, and massive slumping caused large cracks in the ground from which steam emitted” (Stover 3). Consequently, when the geo-process of earthquakes occurs, it molds and changes the earth by creating new geothermal

Volcanoes are in fact important because without volcanoes the atmosphere wouldn’t have its oxygen rich properties. Many of years ago, Earth’s atmosphere was swarm with rock-forming minerals of the earth 's crust. During earlier volcanic eruptions many gasses enters into the earth atmosphere. Carbon dioxide, water vapor and many other gases

Volcanoes are one of the most intimidating natural processes that occur on this planet. Usually they are associated with danger and chaos. Volcanoes are characterized by both their composition and eruption types. In this paper we will be exploring the similarities and differences between three infamous volcanoes, Mt. St. Helens, Mt. Kileaue, and the currently relevant Mt. Agung.

There are many ways to predict volcanic eruptions. Some instruments used are the seismograph, tiltmeters, and satellites. Before all these tools there was no effective way to predict volcanic eruptions. They had to rely on signs like ash coming from the volcano or earthquakes. Sometimes people did not even know there was a volcano! The first instrument invented was the seismograph in about 132 C.E. It was shaped like a cylinder with eight dragon heads around it. The text states “When an earthquake occurred, balls were released from a dragon’s mouth, probably by an internal pendulum that moved back and forth according to the direction of vibration, and were caught by a frog’s mouth, which produced noise.” (https://www.britannica.com Seismograph, by The Editors of Encyclopædia Britannica, last edited on 3-15-2017, 6 April, 2017) Another more recent instrument is called the tiltmeter, which has been used since the 1960s. It measures slight inclinations in the Earths surface. That can tell you of a volcano is in danger of erupting. (https://www.reference.com, “what is a tiltmeter” 6 April, 2017) The most recent way to predict the blasts use salatites. They monitor volcanoes from space they can detect heat, sulfur dioxide, and changes in the earths surface. They cant tell for sure when an explosion will ocurr but they can give good clues about it.

The effect of the volcanic eruption depends on the particle amounts and sizes, their distribution, location in terms of latitude, and the residence time in the atmosphere. After eruptions, the link between the dust injected into the atmosphere via eruptions were observed
