earthquakes in our society

Nowadays, people is not only threatended from diseases, war, but aslo from natural phenomenons.Scientists worry about the increase of the frequency and intensity of earthquakes. An earthquakes happens with a sudden shock and very fast without a warning or a clue. They can occur at anywhere and anytime.However, almost people does not understand big causes and important effects of earthquakes clearly.An earthquakes causes shaking and ground rupture, plate tectonics,can causes damage life and society.
Shaking and ground rupture are the main effect created by earthquakes, principally resulting in more or less severe damage to buildings and other rigid structures. It is principally due to the transfer of the seimic motion from deep soils to soft superficial soils and to effects of seismic energy. An earthquakes is an unpredicable event in which masses of rock below Earth’s surface, realsing big amount of energy and sending out shock waves. That sometimes cause the ground to shake dramatically. Not all earthquakes are enormous but they can become one of Earth’s most destructive forces.
Most earthquakes are caused by plate tectonics. Earth’s crust is created by many huge rocky planets known as tectonics planets.These planets constanly move slowly across the surface of earth,bumping into overrunning each other and pulling away from each other. An earthquakes is a very sudden natural disaster because it can shrivel buildings to a pile of shards in secondary which can kill a large amount of inhabitants. When there is an earthquakes, there is ussually an volcano.
Earthqukes, along with severe storm, volcano activity, coastal waves attack, and wildfire, can produces slope instability leading to landslides, a major geological hazard. Earthquakes can cause fires by damaging electric power. Floods may be thirth effect of earthquakes, may cause landslides to dam rivers,
Earthquakes hazard risk ti the health,safety,and economic viability of many countries and throughout the world.Recent earthquakes demonstrated the risk to morden industrial societies, loss of life, infrastructures damage..Ex:the kobe,Japan earthquakes was another 6,9 magnitude event that same year which caused 5,48 deaths,over 150 billion dollars of damage and a major disruption of Japan’s economy with globar impacts.A earthquakes may lead to diseases, lack of basic necessities,higher insurance premiums, general property damage,rood and bridge damage, and collapse buildings.
For anyone who has experienced an earthquakes, the experiencecan be frightening and traumatic.In addition to the moverment of the ground, people need to be concerned with collapsing buildings.The effects of an earthquakes can also causes dangeous landslides,fire,gasline, and flood waters from collapse dams.This imformation, when share with people on earthquakes in areas, can help decrease the number of deaths and injuries that may occur.
