EARTHQUAKE EFFECTS

Earthquakes, which are measured by Richter scale, are a dangerous natural phenomenon. They happen without warning. They can happen any time of day, at any point during the year. Sometime, an earthquake will be so small that it could not cause any serious damage. However, strong earthquake will result in a lot of bad consequences for our society. The effects of the rumbling produced by earthquakes will lead to the damage of man-made structures, loss of human life and tsunami.
One of the most dangerous effects of an earthquake is the loss of human life. It is said that earthquakes are responsible for around about 10,000 deaths per year. They are the terrible destroyer because they can kill a lot of people at the same time. In fact, there are many real evidences of the violence strength of the earthquake. For example, the 1964 Alaska earthquake, a huge concrete facade fell of a department store onto pedestrians passing by and killed all of them. Another example is the latest earthquake, in 2010 Haiti earthquake, about 200,000 people were killed. However, the exact number will never be know. Also, in the San Fransisco earthquake in 1906 nearly all of people were hurt one way or another.
Another bad effect of an earthquake is the damage of important infrastructure such as buildings, bridges and roads. These infrastructures take an important part in the development of our economic and our life. When the earthquake happen with a strong Richter, the buildings, bridges and roads were destroyed, and it takes a lot of money to rebuilt and repair them, so after the earthquake, our economic will be decreased strongly and our living standard will be lower. For example, in the 2010 Haiti earthquake almost the buildings were collapsed and the citizens have to face to a lot of difficulties.
Beside destroying infrastructure and losing human life, earthquakes that take place under the ocean can cause terrible tsunamis. Tsunamis are giant waves that cause floods and are up to 100 feet tall. They often strike a long way away from the quake, and are very deadly. They are really dangerous. In fact, in the last century more than 50,000 people have died as a result of tsunami. On June 25, 1896 an earthquake of the Japanese coast generated a tsunami that hit the shore with wave heights ranging from 10 to 100 feet and lead to the death of a lot of people especially fish men and tourists who are on the sea.
In conclusion, earthquakes produce various damaging effect to the areas they act upon. Rapid settling and collapse of infrastructures, terrible casualties and tsunami are tree main unavoidable effects of the earthquake. Getting information and knowing how to protect ourselves from the earthquake is really necessary. There are a lot of methods to protect us from earthquake so try to master to use in case there is an earthquake.
