EARTHQUAKES Introduction and Terminology • Vibrations in the earth’s crust that occur when strain in the crust is suddenly released by displacement along a fault line • Focus = point at which an earthquake originates inside the earth. May be many km below surface • Epicentre = the point on the earth’s surface directly above the focus. Strongest shock normally felt here. Most damage usually occurs here. • Seismology = the study of earthquakes – from Greek – seio – to shake

Associate Program Material History of Rock Worksheet Write a 500- to 750-word explanation regarding the role of plate tectonics in the origin of igneous rocks. | Plate tectonics play a major role in the origin of igneous rocks. Igneous rocks are called fire rocks and are formed either| |underground or above ground. Underground‚ they are formed when the melted rock‚ called magma‚ deep within the earth becomes trapped| |in small pockets. As these pockets of magma cool slowly underground

making it susceptible to earthquakes CONSTRUCTION OF EARTHQUAKE RESISTENT BUILDINGS IN SEISMIC ZONES OF INDIA Earthquakes occur due to movements along faults that have evolved through geological and tectonic processes. Often they occur without any prior warning and are‚ therefore‚ unpredictable. The large area of India is prone to earthquake. The construction of earthquake resistant building is the only solution for safeguarding our urban centres from the menace of earthquakes. On the basis of

Earthquakes By: Kayla Marie Vargas Period 4 In earth science they talk a lot about different Earthquakes‚ volcanoes‚ the weather‚ different rocks‚ and etc. But never did you really get in details of what is any of them. Well I did research and found out that an earthquake which is also known as a quake‚ tremor or temblor is a result of a sudden release of energy in the Earth’s crust that creates seismic waves. The seismicity‚ seismism or seismic activity of an area refers to the frequency

Definition: An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves.TThe recent earthquake In India on September 18 ‚ 2011 compelled me to write an essay about earthquake. In this essay many things related to earthquake will be discussed.e seismicity or seismic activity of an area refers to the frequency‚ type and size of earthquakes experienced over a period of time. Measurement: Earthquakes are measured with the help of seismometers. The moment

examples of earthquakes‚ assess the extent to which attempts at prediction and mitigation may have influenced the impact of the hazard. An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. Earthquake is a major threat to the human and natural environments‚ in which people died‚ buildings collapsed and cities destroyed. Prediction and mitigation are usually conducted in order to reduce the impact of an earthquake on environment. Earthquake prediction

By January 24th‚ at least 52 aftershocks (a smaller earthquake following the main shock of a large earthquake)‚ measuring 4.5 or greater had been recorded. An estimate of three million people were affected by the earthquake. Death toll estimates ranged from 100‚000 to 160‚000. 316 total had been affected overall. Estimated 250‚000 residences and
