Seismic waves are produced when some form of energy stored in Earth's crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and "slip." Liquefaction occurs when a material of solid consistency is transformed, with increased water pressure, in to a liquefied state. 2. It causes volcanos, tsunamis, and earthquakes, and it serves to provide, through a change in the landmasses and climate, pushes for the evolution of various species. This disaster occurs due various reasons firstly; when two plates move or slide pass each other enormous tension builds up which creates waves of energy in all directions that leads to quake. 3. Seismic waves are one type of wave and they are seen in earthquakes, which can cause severe damage to human structures and more often than not, humans themselves. Earthquake environmental effects are the effects caused by an earthquake on the natural environment, including surface faulting, [[tectonic tsunamis, soil liquefactions, ground resonance, landslides and ground failure, either directly linked to the earthquake source or provoked by the ground shaking. Ans.1 Earthquake is classified into 4 categories. What is the Earthquake? Ground rupture is a significant rapture consequence of an earthquake. An earthquake causes two major types of seismic waves that move through the earth and cause damage. An earthquake is a natural disaster. It is strange but true that most of the earthquakes seem to occur in the winter season. This fault allows the blocks to move relative to each other. One of the major causes of an earthquake is volcanic eruptions. An earthquake is caused by the sudden shift of the earth's crust, which causes . An earthquake can trigger many sudden changes in the environment which can be classified as primary (e.g. An earthquake is caused by a sudden crack or break in rocks that then slide past each other. Earthquake damage from fires is the most important secondary effect. Causes of Earthquake Earthquakes are caused by sudden tectonic movements in the Earth's crust. earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth 's rocks. What Causes an Earthquake? Formation of cracks or fissures especially in the region of the epicentre is common. Effects of an earthquake. It affects the mental health and emotional health of people. What is cause of Earthquake | Effects of Earthquake But most of them are not of great concern for civil engineers, only a few of them, having high intensity, is a cause of major concern. An earthquake is a sudden movements, vibration or oscillation in the earth crust caused by sudden release of heat and enormous pressure. This type of Earthquake is weak in intensity. It is a phenomenon when the sediments are shaken by the earthquake and are transformed into a flowing liquid mass. This continues until the stress rises and breaks, suddenly allowing sliding over the locked portion of the fault, releasing the stored energy as . These plates are constantly moving because of convectional currents in the mantle (asthenosphere). 738 Words3 Pages. Effects of Earthquake.

The 1959 Hebgen Lake earthquake (also known as the 1959 Yellowstone earthquake) occurred in the western United States on August 17 at 11:37 pm in southwestern Montana.. Earthquake can also cause floods and landslides. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. As of now, the world's most damaging earthquake was in Chile, on May 22, 1960, and it . Earthquake can also cause floods and landslides. A sudden movement of the earth's crust, sudden release of extreme energy, shaking or trembling of the crust of the earth due to shifting of rocks under the earth's surface or underground volcanic forces can be called as earthquakes. The main cause is that when tectonic plates, one rides over the other, causing orogeny collide (mountain building), earthquakes. The Consequences of earthquakes Are all those situations that happen after a quake occurs. The quaking and trembling of the earth's surface due to the movement of plates is known as an earthquake. Earthquake in many cases can cause great loss of life. Japan Earthquake. 2. Effects of an Earthquake: 1. The Northridge earthquake caused numerous ground-surface failures across a broad area of southern California.Failures occurred from the southern parts of Los Angeles County to the Kern County line on the north, and from coastal Ventura County on the west to the . Water, mud and gases are ejected from beneath the fissure. 6. Planet Earth is made up of a solid core, which is followed by a next layer called the mantle, which is liquid. Ground shaking is caused by . Some of them have been mentioned below: The quick shaking of the surface is the most noticeable effect of an Earthquake. However, man-made factors also play a role in this force majeure. The source of the plant is known that 90% of the tsunami is caused by tectonic earthquake activity, 9% due to volcanic activity and 1% by soil landslides that occurring in water such as in the lakes or in the ocean or landslides that came from land which is enters to the ocean. Earthquakes' effects range from many aspects, one of which is in terms of environment. Effects of an earthquake Earthquake produces various damaging effect in the areas the act upon. The study of earthquakes is called as seismology and the instrument used to measure seismic waves is called as seismometer or seismograph. Q.2 List some of the effects of the earthquake. When we speak of earthquakes, we mean any earthquake movement that arises through the movement produced in earth faults, all coming from some movement in the tectonic plates. Most earthquakes are the consequence of natural geological processes , such as the movement and collision between tectonic plates: the masses of the earth's crust that float in the magma inside the planet, and that move very slowly, generating friction with each other. Tsunamis are a series of water waves caused when the seafloor moves vertically in an earthquake . As it may be seen there are many different effects that originate as a result of continental drift, of which earthquakes are one such example. The study "Haiti Earthquake - Causes and Effects" explains earthquakes occur as a result of fracture and displacement of tectonic plates, as happens regularly in Haiti. One of the most catastrophic effects of an earthquake is a tsunami. Liquefaction and subsidence of the ground are important effects which often are the cause of much destruction in earthquakes, particularly in unconsolidated ground. The figure does not include landslides caused by earthquakes. One of the most catastrophic effects of an earthquake is a tsunami. This was a quake that had two strong tremors, and caused utter destruction in some areas of the Sichuan Province. Earth was hot when it formed, and has been cooling ever since (near the surface, for each km into Earth, the temperature rises by about 30deg. Clearing rubble after an earthquake, Bhuj, India.

Causes and Consequences of Earthquakes Earthquakes are one of the most destructive natural disasters that plague life on earth. Many building, hospitals, schools, etc are destroyed due to it. There are several aftereffects of Earthquakes. Sometimes, the earthquakes cause emergence of costs and bring fertile shore out of water to give chance to develop crop production. Liquefaction; Liquefaction is one of the major side effects of the earthquake. This is often accompanied by terrible noise. The earthquakes sometimes cause submergence in coastal land, and result in formation of inlets, bays and gulfs which help to develop of fishing and shipping etc. First off, earthquakes affect humans in many ways. Now, after five years of work, the council's Committee on the Alaska . What is earthquake and its causes and effects? It sends, basically, a sound wave, a shockwave through the ground. The main cause is that when tectonic plates, one rides over the other, causing orogeny collide (mountain building), earthquakes. It refers to a sudden movement and shaking of the earth's surface due to seismic waves passing through the earth's rocks. Therefore, the magma streams in the cracks and builds up more pressure leading to more cracks resulting in small earthquakes. 9‚Oct.2011 Outline I .Introduction: A. Hook: Japan was hit by the most powerful earthquake in recorded history on March 11‚ 2011.B. The severity of these consequences will depend mainly on the magnitude of the earthquake and the context in which it occurs. Some environmental effects occur due to the earthquake are surface faulting, tectonic uplift and subsidence, tsunamis, soil liquefaction, ground resonance, landslides, etc. On 15th June 1896 the Sanriku coast was struck by a devastating tsunami with a maximum wave altitude of 38.2m, causing 22,000 deaths! It may be due to faulting , folding, plate movement, volcaninc eruptions and anthropogenic factors like dams and reservoirs. Earthquake causes damage to the building, bridges, dams…. Damage to infrastructure. The first of these are body waves, which travel directly through rock and cause the vertical and horizontal displacement of the surface. This earthquake was the result of a concentrated slip along an estimated 36km long portion of the Enriquillo-Plantain Garden fault zone. The two major effects caused by earthquakes are shaking and ground rupture. Epidemic outbursts. Earthquake losses, like those of other disasters, tend to cause more financial losses in industrialized countries and more injuries and deaths in undeveloped countries. The intensity of the damage is defined by the magnitude of the earthquake, the distance of the area from the epicentre or the origin of an earthquake, and the geological and geomorphological conditions of . The largest fault surfaces on Earth are formed due to boundaries between moving plates. The magma produces forces on the rocks that crack the rock. These landslides resulted in the death of over 32,322 people. Earthquakes occurring in the ocean floor, or inland nearby the ocean, are by far the most common cause of tsunamis. This research result is astonishing considering the number of people killed by landslides. Land shaking, surface faulting, ground collapse, and, less frequently, tsunamis are all consequences of earthquakes. Page 4-2 Earthquake Effects Liquefaction Strong ground motion during an earthquake can cause water-saturated, unconsolidated soil to act more like a dense fluid than a solid; this process is called liquefaction. Subsidence can then follow as the soil recompacts. The slide blocked the flow of the Madison .
