Essays on Earthquake

Economic is the main factor that drives a country forward because it generates income and shows stability of the country which helps every business run smoothly and draws interests of investors. However, it is hard to control the stability when natural disaster strikes because many things are hard to predict especially for big disasters like the Tsunami and earthquakes. If natural disaster occurs, it can become a nightmare for the economic as a whole. Unfortunately, Japan had encountered with ...

Earthquake predictions effect many a people around the world and have different outcomes. Two specific cases of earthquake predictions will be discussed and compared to each other to see how the public was affected over all. One case is the Parkfield Earthquake in California and the second case is the L’Aquila Earthquake in Italy. There will be several pieces of the earthquakes that will be discussed: geology around the area, what information was gathered before the earthquake, information ...

If two pieces of Earth, all of the sudden slip past each other then an Earthquake will follow. Faults, fault lines or fault planes are surfaces that slip past each other. An earthquake starts in the hypocenter, which is located beneath Earth’s surface. The epicenter is located right above Earth’s. Sometimes large earthquakes have a foreshock. Earthquakes that are smaller than the mainshock that happen after a bigger earthquake in the same place are called foreshocks. Mainshocks are what the ...

An earthquake is when two parts of the earth suddenly slip past one another. The surface where they slip past one is called fault or fault plane. The spot below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of our planet earth is called epicenter. Earthquakes are the result of plate tectonics, or shifting plates in the crust of Earth, and quakes occur when the frictional stress of gliding plate boundaries builds and ...

Death Valley, one of the hottest places in the world, is the centerpiece of the Death Valley National Park in Eastern California. Death Valley was formed as a part of a graben. To the east of the San Andreas Fault System (SAFS) lies a tectonically active region called the Eastern California Shear Zone (ECSZ). The SAFS is the biggest indicator of activity between the Pacific and North American plates, but the ECSZ contributes 10-14 mm/year of movement along three fault zones: the Death Valley ...

In the world, there are currently multiple areas in which the interaction of tectonic plates can be represented. I am going to discuss how, as well as provide scientific reasoning to justify the features provided on the surface of the earth due to the Himalayan mountains. The phrase Himalaya, comes from a Sanskrit word meaning Abode of Snow. Due to such snow on the mountain. The Nepalese meanings for hima from 'snow' and ālaya for 'abode meaning home. But for buddhists cases, the himalayan ...

TOHOKU, Japan, Friday, Mar. 11 -Yesterday, a 9.0 magnitude Earthquake struck the east of Tohoku, Japan. The epicentre of the earthquake was located approximately 72 km east of Tohoku (38.3 degrees North latitude and 142.4 degrees East longitude), or 130 km east of Sendai as shown by the X in figure 3 below. The focus of the earthquake was 24.4 km under the epicentre. The earthquake therefore caused a tsunami due to the displacing of water above the Pacific Plate. The earthquake and tsunami ...

Earthquakes can devastate a city. They are a force of nature that can destroy any structure. The earth is made up of moving tectonic plates. Earthquakes occur along or near tectonic plate boundaries where two plates meet. These plates are solid rock and sit on the mantle which is a layer of molten rock. This molten rock is constantly moving in a convection current. The earth’s core is what generates the heat. The hotter rock rises away from the core and pushes up against the crust. Here it ...

Passive Seismic Control Systems are called passive because they do not require any additional energy source to operate and are activated only by the earthquake input motion. They are divided into three different types: Energy Dissipation Devices Base Isolation Devices Dynamic Oscillators Passive control of structure can be obtained with the introducing of viscoelastic material into the structure, by the adoption of dampers, or with the so called tuned mass dampers. Through internal ...

So far this century there have been more than 1,100 fatal earthquake causing a total loss of life exceeding 1. 53 million people. Reducing the loss of life is the primary protection strategies, and yet the processes that contribute to death tolls and the best strategies for for reducing injury levels are not well understood (Coburn, Spence & Promonis, 1992). When a strong earthquake hits an urban area, structures collapse, people are injured or killed, infrastructure is disrupted, and business ...
