measure of the magnitude of seismic waves from an earthquake. Devised in 1935 by the American seismologist Charles F. Richter (1900–1985) and technically known as the local magnitude scale‚ it has been superseded by the moment magnitude scale‚ which was developed in the 1970s. The Richter scale is logarithmic; that is‚ the amplitude of the waves increases by powers of 10 in relation to the Richter magnitude numbers. The energy released in an earthquake can easily be approximated by an equation that

This article that I have chosen is a earthquake that happened in China. It was said that this earthquake had the largest measuring magnitude of 5.7. After the earthquake‚ at least 80 were killed and 700 were injured. This earthquake was the heaviest in the rural area in Yiliang country. One of the elementary school collapsed in the earthquake. Authorities are not sure if the children are killed. In 2008‚ there was an earthquake in Yunnan’s neighbouring Sichuan province‚ which killed 80

Three hundred hospitals with 20 beds or more in Tōhoku were damaged by the disaster‚ with 11 being completely destroyed. The earthquake and tsunami created an estimated 24-25 million tons of rubble and debris in Japan. An estimated 230‚000 automobiles and trucks were damaged or destroyed in the disaster. As of the end of May 2011‚ residents of Iwate‚ Miyagi‚ and Fukushima prefectures

Earthquakes in Japan The Japan is located in an area where several continental and oceanic plates meet and create a major fault line; this is the cause of frequent earthquakes and the presence of many volcanoes and hot springs across Japan. If earthquakes occur below or close to the ocean‚ they may trigger tidal waves known as tsunami. Historic earthquakes Here is a brief history of earthquake in Japan. Many parts of this country have experienced devastating earthquakes and tidal waves in the

Earthquakes in GCC An Earthquake known also as tremor is resulted from a sudden release of energy ‚which takes place in the earths crust‚ which then creates seismic waves. They are vibrations triggered by movement of rocks that have been strained (deformed) beyond their elastic limit. This activity called seismicity or seismism of an area refers to type ‚ size and frequency over a time period. Earthquakes are measured using many instruments ( up to atleast 20 different types

Chile Earthquake Script Earthquake On February 27th 2010 at 3:34 an earthquake with a magnitude of 8.8 occurred in Chile. The earthquake lasted 90 seconds and affected a total of 6 Chilean regions but the earthquake mainly occurred offshore of Maule region. The earthquake left 93% of Chile’s population with no electricity. This earthquake not only damaged Chile but it has permanently shortened the length of our days by 1.26 microseconds and moved the earth’s axis by 8 centimetres. Tsunami

Joan d’Arc lived during the Hundred Years War‚ a very turbulent time in Europe’s history. Throughout her life Joan faced many challenges‚ from rising from an insignificant peasant girl‚ to end up saving France from the English as she was instructed by three saints who came to her in a vision. When Joan came into control of Charles VII’s troops‚ Joan won many key battles for the French until she was captured by the English in 1430. Joan d’Arc had a major impact on the world‚ not only because of her

San Francisco have all experienced a fault shift. In the case of Houston‚ the likelihood of an earthquake is extremely low. The instances of a fault shift on that area of the North American Plate don’t occur often. Earthquakes that occur are not by normal means of plates shifting but from the process of fluid extraction (Fehling 19). Seattle on the other hand has a very high probability of an earthquake occurring. There are three different types of quakes that the city experiences crustal quakes‚

The location of the epicentre was Bhuj (23.6° N 69.8° E) Gujarat‚ India. With a moment magnitude (Mw) of between 7.6 and 8.1‚ the quake killed more than 20‚000 people and injured another 167‚000 and destroyed near a million homes throughout Gujarat and parts of eastern Pakistan.[3] The earthquake is considered an intraplate earthquake because
