5 Common Psychological Effects One Might Experience After Surviving a Major Earthquake

Therefore, there are three effects of earthquakes : tsunamis, volcanoes, and landslides. Fires Earthquakes can cause fires by damaging electrical power or gas lines. We know nowadays that the effect of soft soil on buildings during an earthquake is disastrous 1984the Mexico City earthquake and the houses in the Marina District were very badly affected. Most buildings stood up,to the shaking fairly well. Fault lines are the specific locations of each fault, and they are continually studied and monitored by earth scientists. There can be more than thousand people buried in the wreckage is just because of earthquake and most of them definitely is death.

Damage considerable in specially designed structures; well-designed frame structures thrown out of plumb. When it happens, everything that it crosses is destroyed. Often unstable regions of hillsides or mountains fail. The energy radiates outward from the fault in all directions in the form of seismic waves like ripples on a pond. The energy released in earthquakes from this belt is about 15 percent of the world total.

About Liquefaction

B these phenomena are usually explained in terms of a release of g prior to earthquakes and electric and acoustic stimuli of vari types. See how the top deck of the Freeway has collapsed onto the lower deck. The soft soil shook so much harder than the firm ground elsewhere in the city, tha it shook all the ground water up,to,the surface and turned the ground into a wet soft surface, not unlike a seaside beach. Landslides - In mountainous regions subjected to earthquakes ground shaking may trigger landslides, rock and debris falls, rock and debris slides, slumps, and debris avalanches. Robert Herrmann, Saint Louis University Strengthening Structures We have two approaches for preparing buildings for earthquakes: you either secure the building components walls, floors, foundation, etc. Surface faulting, which we recognize as fractures in the earth, could be classified into three different types.

This effect is called site or local amplification. Factories and power plants affected by the earthquake can release toxic chemicals which can pollute the atmosphere and the area around it which can have a harmful effect on society. But… what is an earthquake? Collective resilience is the only solution towards dealing with any kind of natural catastrophe. The choice of building design is a compromise between appearance, function, structure, strength, and of course, cost. In the largest earthquakes whole districts can be devastated by the multiple consequences of ground shaking. Impact projections suggest the flood could affect roughly 5 million people. Felt by nearly everyone; many awakened.

Cause and Effect of Earthquakes Essay

Global warming heats water from oceans and seas. Earthquakes are one of the terrible outcomes of nature, and they bring a lot of big problems to humans and the animals. However, the actual effects continue for many years after the natural disaster strikes. About 10 months earlier, an earthquake with moment magnitude 6. Changes in Ground Level - A secondary or tertiary effect that is caused by faulting. It then collects into rivers lakes or oceans that may be evaporated to start the process all over again.

What Are the Effects of a Tsunami?

And now, those who managed to survive must face the aftermath of the terrifying tragedy: from rescuing victims trapped in the rubble, to cleaning up the mess left behind, to—perhaps most difficultly—picking up the pieces of their own personal devastation. Tsunami are long-wavelength, long-period sea waves produced by the sudden or abrupt movement of large volumes of water — including when an earthquake occurs at sea. They are often formed from earthquakes occurring in the oceanic crust. This was observed for example during more or less catastrophic seismic events recently occurred in very different parts of the world. The latest earthquake in Japan has damaged the nuclear reactor which has led to nuclear radiation in the country. Tsunami Initiation A sudden offset changes the elevation of the ocean and initiates a water wave that travels outward from the region of sea-floor disruption.

Harmful Effects of Earthquakes

Tsunamis are initiated by a sudden displacement of the ocean, commonly caused by vertical deformation of the ocean floor during earthquakes. Those 185 lives lost represents the mothers, fathers, uncles, aunts, grandparents, friends and neighbours that were taken by a force that even the strongest machines break under. When it fractures, it generates earthquakes that define a zone of earthquakes with increasing focal depths beneath the overriding plate. The amount of structural damage that can occur during an earthquake with a magnitude of 4. They are one of the world's worst natural disasters that can hit a country. Each structure has a resonance frequency that is characteristic of the building. During an earthquake, the ground vibrates in a similar manner, as waves of different frequencies and amplitude interact with one another.

Standing motor cars rocked noticeably. If they draw a circle on a map around the station where the radius of the circle is the determined distance to the earthquake, they know the earthquake lies somewhere on the circle. Occasionally large landslides can be triggered by earthquakes. Forecast of earthquakes: Earthquakes occur suddenly without warning. Floods The destruction an earthquake likely to cause is definitely an unpredictable one.

Magnitude measures the energy released at the source of the earthquake. Liquefaction is the mixing of sand or soil and groundwater water underground during the shaking of a moderate or strong earthquake. See the of major earthquakes. Some Major Earthquakes: Some major recorded worlds over earthquakes are mentioned below: 2. Earthquakes may be of different intensities which determines how much damage it causes to life and property. In deep water tsunamis are not large and pose no danger. Although they are the first waves recorded by instruments such as seismographs, they do very little damage but, secondary waves travel through solids.

The P waves travel faster and shake the ground where you are first. These are long-wavelength and long-period sea waves. The effects of a tsunami are devastating. Check out the before and after photos. Earthquakes and their Occurence What is an Earthquake? However, periodicities in time and space for major earthquakes have not been widely detected or accepted. When this earthquake ground motion occurs beneath a building and when it is strong enough, it sets the building in motion, starting with the buildings foundation, and transfers the motion throughout the rest of building in a very complex way.
