However, such earthquakes are of very small magnitude and do not cause any damage to life and property however, there are certain exceptions due to the construction of marathon dam in 1929, there was a severe earthquake in greece in 1931. Reply to ask-an-earth-scientist subject: what causes earthquakes what causes earthquakes the short answer is that earthquakes are caused by faulting, a sudden lateral or vertical movement of rock along a rupture (break) surface. Causes and effects of earthquakes, tsunami and cyclones earthquakes what are earthquakes ← an earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the earth's crust that creates seismic waves.

causes and efeects of earthquakes A powerful earthquake can cause landslides, tsunamis, flooding, and other catastrophic events most damage and deaths happen in populated areas that's because the shaking can cause windows to break, structures to collapse, fire, and other dangers.

Chile earthquake of 1960: chile earthquake of 1960, the largest earthquake recorded in the 20th century originating off the coast of southern chile on may 22, 1960, the temblor caused substantial damage and loss of life in chile and—as a result of the tsunamis it generated—in hawaii, japan, the philippines, and other distant coastal areas. What causes an earthquake an earthquake is a sudden tremor or movement of the earth's crust, which originates naturally at or below the surface the word natural is important here, since it excludes shock waves caused by french nuclear tests, man made explosions and landslides caused by building work. When an earthquake causes the ground to shake, the base of the seismograph shakes too, but the hanging weight does not instead the spring or string that it is hanging from absorbs all the movement.

Earthquake: earthquake, any sudden shaking of the ground caused by the passage of seismic waves through earth’s rocks earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another. Liquefaction and subsidence of the ground are important effects which often are the cause of much destruction in earthquakes, particularly in unconsolidated ground liquefaction is when sediment grains are literally made to float in groundwater, which causes the soil to lose all its solidity. Intraplate earthquakes the ones that take place away from the plate boundaries are known as intraplate earthquakes the primary cause of this type is the presence of tectonic faults in the earth's crust.

Causes and effects of earthquakes 1 • causes of earthquakes • effects of earthquakes 2 natural cause: earthquakes are the result of slow-moving processes that operate within earth earth was hot when it formed, and has been cooling ever since (near the surface, for each km into. Earthquake-like seismic waves can also be caused by explosions underground these explosions may be set off to break rock while making tunnels for roads, railroads, subways, or mines these explosions, however, don't cause very strong seismic waves. These waves of energy cause the ground to reverberate and send shockwaves through the earth this is the destructive part of the earthquake, as most buildings aren't designed to have their foundations moved and shifted. That's what causes an earthquake the 70 quake that struck haiti was the same strength as the loma prieta earthquake that struck san francisco during the 1989 world series but haiti's quake was 62 miles below the surface.

Causes and efeects of earthquakes

Earthquakes are caused by disturbances in the interior of the earth and other causes it is true that the earthquakes can happen in any part of the world but in the areas of faulting and folding or of crustal weakness, the frequency of earthquakes is more than anywhere else the earthquakes are . What causes earthquakes the shaking motion of an earthquake is the result of a sudden release of energy earthquakes are caused when stress, building up within rocks of the earth's crust, is released in a sudden jolt. A substantial number of earthquakes in one region of oklahoma over the past several years can be linked to the process of hydraulic fracturing, ie, fracking, according to a new study from . Q: what is an earthquake and what causes them to happen ans: an earthquake is caused by a sudden slip on a fault stresses in the earth's outer layer push the sides of the fault together.

Advertisements: earthquake is a phenomenon generally considered in the context of volcanic activity an earthquake is the shaking or trembling of the earth, caused by the sudden movement of a part of the earth’s crust. Natural events such as volcanic eruptions and meteor impacts can cause earthquakes, but the majority of naturally-occurring earthquakes are triggered by movement of the earth's plates. The rippling effect is what causes the rapid and violent vibration of the earth surface – earthquake, shaking and tearing everything on it including the earth surface itself, structures, and houses.

When we discussed earthquake intensity we discussed some of the basic factors that affect the amplitude and duration of shaking produced by an earthquake (earthquake size, distance from fault, site and regional geology, etc) and as you are aware, the shaking caused by seismic waves can cause damage buildings or cause buildings to collapse. Earthquakes are caused by tectonic movements in the earth's crust the main cause is that when tectonic plates collide, one rides over the other, causing orogeny (mountain building), earthquakes and volcanoes. The cause and effect of the tsunami in thailand in 2004 the tsunami in thailand that occurred on december 26, 2004, was by far the largest tsunami catastrophe in human history it was triggered by a magnitude 91-93 earthquake along the indian-australian subduction zone off the northern coast of sumatra.
