Causes Of Natural Disasters

A natural disaster has the capability to cause large scale damage and destruction to an area. Seismic events have been known to alter landscapes and affect the livelihoods, health and development of communities. No two earthquake events are the same and the level of threat posed by an earthquake can vary due to both the human and physical factors of an area. The 2010 magnitude - 7.0 earthquake that occurred in Haiti is an example of where a natural disaster caused a previously vulnerable area to suffer tremendous loss and debilitating socio-economic impacts, to an already poverty-stricken nation.

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

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

The volcanic eruption of Nevada del Ruiz in Bolivia is another example of how some of the poorest people can be so badly affected by these events. The US volcanologist office warned the local authorities about the impending eruption but the authorities did not understand the seriousness of the situation and so did not warn any of the people. 28000 people died from the eruption and the secondary effects of the mudslides and lahars that formed. This lack of education of the risks of the seismic and volcanic hazards in the poorer countries often makes them much more vulnerable.

Currently with japan having so many earthquakes because of its location on 4 plates, we dont really know about volcanic earthquakes but nevertheless it exists.

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

On the morning of May 18, 1980, the United States of America experienced its deadliest and most destructive volcanic eruption in history. Briefly succeeding a magnitude 5.1 earthquake, an enormous slab of Mount St. Helens northern flank collapsed in a massive debris avalanche. This landslide was the largest to transpire on Earth in recorded history and caused the volcanoes magma system to depressurize. With the cap of the mountain removed, superheated gases and rock fragments blasted through the side of the mountain (USDA, 2005). The lateral blast accelerated at speeds of 480 km per hour and reached temperatures of 350 °C, creating an immense area of leveled and scorched forestry. Surges of water from melting snow and glaciers capping

Earthquake Hazards occur when there are adverse effects on human activities. This can include surface faulting, ground shaking and liquefaction. In this essay I will be discussing the factors that affect earthquakes, whether human such as population density, urbanisation and earthquake mitigation or physical such as liquefaction, magnitude, landslides and proximity to the focus.

The science behind an earthquake is really interesting. First, an earthquake is supposed to be sudden, not just a switch. The earthquake simulator I used was hand built, and it was just shaking, not erupting. An earthquake has shaking, but also many phases, which each phase has different forms of shaking, which can equal an eruption. The earthquakes have foreshocks.

In these eruptions, instead of the mixture of gas and ash flowing upwards, it flows outwards and hugs the ground. These eruptions are extremely dangerous.

     Most of the worst earthquakes are associated with changes in the shape of the Earth's outermost shell, particularly the crust. These so called tectonic earthquakes are generated by the rapid release of strain energy that is stored within the rocks of the crust, which on continents is about 22 miles thick. A small proportion of earthquakes are associated with human activity. Dynamite or atomic explosions, for example, can sometimes cause mild quakes. The injection of liquid wastes deep into the Earth and the pressures

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.

This paper will discuss the differences between two different natural and man-made disasters. The disasters that will be discussed are Hurricane Katrina and the Deepwater Horizon oil spill. Additionally, this paper will look into the specifics of what constitutes a natural and man-made disaster. Specifically, this paper will look into each disaster to include the events surrounding them; the risks; and the assessments. Furthermore, this paper will look at some of the details of each disaster and why there was so much devastation. Finally, this paper will look at a few similarities, but mainly the differences between the two, and how the effects of each still linger today.
