Extract of sample "Epicenter and Magnitude of the Earthquake"

Download file to see previous pages To locate the epicenter of the earthquake, the seismologists examine seismograms from three seismic stations. The seismologists measure the time interval of S-waves and P-waves in about 45 seconds and place the vertical lines at an interval of about 2 seconds. The measured S-P time interval will help to determine waves distance of travel from the focus to the station. It is paramount to note that the actual location of the epicenter is on the circle's perimeter to be drawn around the station. Therefore, to triangulate this position, there must be three seismic stations. A circle with an appropriate radius is drawn around every station and where the three circles intersect is the epicenter of the earthquake.
 The seismologists use a well-known Richter scale to measure the magnitude of an earthquake. To determine the earthquake’s Richter magnitude, seismologists require one to know the surface the wave’s amplitude and the distance to the origin of the earthquake at the seismic recording site or location. The distance of the seismic recording and footage station from the epicenter can be determined by getting the time difference between the arrival of the P-waves and S-waves at the station. The difference is called S-P interval. The amplitude of the surface wave depends on the earthquakes magnitude and the distance between the epicenter and recording station. It is a measure of how many millimeters the ground will move at the recording station. The amplitude and S-P interval is then used to determine the Richter magnitude. ...Download file to see next pagesRead More

...that they can sustain at least similar, if not more severe, earthquakes in the future. Case Study: Earthquake in Pakistan, 2005 Pakistan was struck by one of the most disastrous earthquakes in the history at 8:50 am on 8 October, 2005. This earthquake was of the magnitude 7.6 (Monalisa, Khwaja, and Shehzad 7). Its epicenter was almost 65 miles toward the northeast of Islamabad that is the capital of Pakistan. In this earthquake, some 86,000 people lost their lives while another 69,000 were bruised and badly injured (“2005 Pakistan Earthquake”). The northern areas in Pakistan were extensively damaged as a...

... already started. The fault started to slip, resulted in tsunamis. The waves due to the tsunamis were around 70 feet in height. The ground seemed to rush under the foot. Huge fissures began to open and close as the shaking continued. In a moment every thing started to come down and collapse. For around 5 minutes the ground shook like anything and than it stopped, leaving every thing ruined and devastated. (1) The epicenter was 55 miles west of Valdez and 75 miles east on Anchorage. First moving on the seismic perimeters, the magnitude of this quake was noted to be 8.4 on the RICHTER SCALE. But later the calculation of the movement proved it to be around 9.2, holding it to be the second largest quake after the CHILE earthquake... which...

Earthquake Impacts

..., with 716 aftershocks recorded by 10 AM as of January 18, 1996, 74 of these could be felt by the human body, and 14 of these occurred on the 18th. The epicenter of the earthquake was 20km underneath the island of Awaji, across a strait from Kobe. With a magnitude of 6.9 (Mw) and a duration of roughly 20 seconds, in regards to the structural damage caused by the earthquake, there were: 144,032 buildings destroyed by ground shaking, 7,456 buildings destroyed by fire, 82,091 collapsed buildings, and 86,043 severely damaged buildings. All Kobe ports were shut down to international shipping, there was substantial damage to containing loader piers, and all access to Kobe via...

Richter Magnitude

...Earthquakes Standing in a room that is shaking, the ground or floor like water, the sound like a freight train: these are the experiences of an earthquake. Earthquakes happen on a daily basis throughout the world, many small and unnoticed. A large earthquake, however, can affect not only cities but entire nations. Sometimes even the earthquake is not the most dangerous development; a tsunami or landslide can occur and be even more deadly. Mathematical Equation Measuring the size of an earthquake is a mathematical process that not everyone agrees on. The most common method for determining the size of an earthquake is...

... as it measured 4.1 on the Richter scale. Blood was everywhere; within houses, towers and malls – all of them were destroyed. Children were walking and shouting for their parents, dust was covering the place, people were shouting and screaming as the view was terrifying. I didn’t know what I should have done as I was very shocked. An earthquake is a vibration of the Earth produced by a rapid release of energy (Tarbuck 1996). The main features include the focus, the location within the Earth where the earthquake rupture starts, and the epicenter, the point on the Earths surface directly above the focus. Earthquakes have a greater effect on society than most people think. These effects range from economical to structural to mental... ...

Haiti earthquake

...Your full November 14, Article Summary The article on BBC News is about Haiti that suffered from a massive earthquake of magnitude 7.0 and two aftershocks. The tremor hit the south of the capital Port-au-Prince and wrecked the whole region resulting in thousands of deaths, reported and unreported. Millions of people were affected. Many nations provided their aid. Many UN personnel and peacekeepers of China, Jordanian and Brazilian Army were reported to be dead or missing. Many tourists in the Hotel Montana died. Overnight looting also took place due to total darkness. A lot of dead bodies could be seen on trucks when people were digging them out under flashlights. Haiti has seen many natural disasters in the past. The next section... of the...

...Earthquake: Japan, Chile, and Haiti In terms of Richter magnitude size, Japan’s earthquake registered at a moment magnitude of 9.0 on the Richter scale (USGS, 2011). The Haiti earthquake on the other hand registered at an intensity of 7.0 (Disasters Emergency Committee, n.d), and the Chilean earthquake registered at a magnitude of 8.8 (Reuters, 2010). In Japan, the thrusting of the Pacific plate under the North American plate caused the earthquake; Japan is located on top of the North American plate (New York Times, 2011). In Chile, the earthquake was caused by the movement of the Nazca and South American tectonic plates. The earthquake was marked by a thrust-faulting focal mechanism which saw the subduction of the Nazca plate... ...

...terms happens when the rocks break due to pressure upon them. The spot where the rock breaks is the epicenter of earthquake. In the past decade, world has faced some frightening earthquakes which threatened people regarding the wrath of Mother Nature. People are recently more scared of earthquakes than any other natural disaster and also due to its connection to tsunamis. The major earthquake is the one happened in Japan in 2011. It not only caused heavy damage but also had been a reason for a massive tsunami. According to ( Kurtenbach) “The magnitude-9.0 earthquake and ensuing tsunami that slammed into...

...Due Causes and Effects of Earthquakes There is no doubt that wherever it has occurred with weighty magnitudes, it is indeed frightening and most certainly with unusual characteristics; the pain, the damage and absolute losses are always inerasable in peoples’ hearts. To many, the term Earthquake embodies sad memories, heartaches, and to the very extreme, death. From doctrinal mythology that rendered them acts of punishments from the Most High just a century ago to modern science, the human race has come full circle to diagnose exactly how it happens as well as its very causes. By definition, an Earthquake is but a tremor/vibration of the Earths crust as a result of...
