Earthquake And Earthquakes Essay

The San Andreas fault line has caused constant development nightmares for large urban areas such as San Francisco as well as the other cities built on top of it. Fault lines are one of the side effects of the earth’s tectonic plates shifting that can result in devastating earthquakes. Some of the most devastating earthquakes in our modern era have occurred along the San Andreas fault line due to a dense population. The most notable and destructive earthquake on the San Andreas fault line occurred in San Francisco in 1906. The reason this earthquake was so deadly was because of its magnitude and the city’s poor planning. This earthquake was a wakeup call for San Francisco and force the city to revolutionize its knowledge on earthquakes and how to protect their city. Today San Francisco is one of the most well prepared cities for an earthquake and has made great discoveries in earthquake safety measures. The 1906 earthquake in San Francisco has drastically changed how the city has developed its zoning and building code policies, and its earthquake research.

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

Volcanoes can be found throughout the entire world and are formed when there is a rupture in the mantle of the Earth's crust. This effect allows the output of volcanic lava, ash, and various types of gases. These tectonic plate breaks are normal, the planet Earth is divided into 17 tectonic plates and consistently move against each other forming shifts from low to high intensity. It can cause displacement of earth or water.

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.

With earthquakes on the rise, we must figure out the cause of them and determine a solution to help limit or even prevent them from occurring. Since early 2009, earthquakes have been sweeping across the state of Oklahoma, causing many people to worry about their own well-being. Many scientists speculate the source of the earthquakes might be a result of Hydraulic Fracturing deep down in Earths’ crust. Hydraulic fracturing is a process in which oil and natural gas companies pump up to millions of gallons of wastewater, sand, and chemicals down drilled holes in order to release pockets of shale within the earth. This use of technology is in question of the potential cause or inducement of earthquakes in

The San Francisco Earthquake written by Jack London is journal of his events throughout the devastating acts of God that hit San Francisco in 1906. (461-466)

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

Of all the naturally occurring events on Earth, earthquakes are among the most devastating and bring a lot of truth to the statement, “Just because something is natural does not mean it is not dangerous.” Earthquakes are one of the most natural things I can think of that can cause massive damage and loss of human live in many instances, and the effects are sometimes long term. “Nothing happens without a force. Many geophysicists accept the theory that continents move as a result of the forces generated by mantel convection deep within Earth – motions driven by our planet’s internal heat energy” (Trefil & Hazen, 2010). According to National Geographic (1996-2012), constant movement in the tectonic plates that make up the Earth’s

Plate tectonics are very dangerous when they collide,slide,and move apart. They can create mountains like the Appalachian Mountains that used to tower over everything then erosion took place. The Appalachian Mountains were formed by convergent boundaries, convergent boundaries are collide

A ‘hazard’ can be defined as a geophysical process operating within the lithosphere, atmosphere, hydrosphere or biosphere which could potentially lead to the loss of human life or property. However, an earthquake only becomes hazardous and therefore needs management if it occurs within close proximity to a vulnerable population. To some extent, any human settlement around the world situated close to or on top of an area of seismic activity is vulnerable. However, not all nations suffer equal devastation.

A hazard can best be defined as a 'situation that poses a level of threat to life, health, property or the environment.' The overall impact of earthquakes as a natural hazard varies greatly from one place and timeframe to another. As do the types of hazards, which are categorised into primary and secondary. Primary hazards are created by the direct seismic energy of an earthquake; this could include liquefaction, slope failure and tsunamis. These primary hazards can in turn trigger secondary hazards such as floods, fires, disease and destabilisation of infrastructure. A number of factors play a part in determining the severity

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.

     Although it is certain that violent Earth tremors in themselves are destructive, there are often other kinds of Earth movements that are triggered by earthquake shock waves. Thus, the violent shaking that accompanies many earthquakes often causes rockslides, snow avalanches, and landslides. In some areas these events are frequently more devastating than the Earth tremor itself.

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.
