Effects of the earthquake.

Earthquake is one of the most dangerous natural disasters that cause serious effects on the society. An earthquake comprises of many kinds of waves in which the Seismic is the most remarkable one. It directly causes the damaging of structures; destroys the nation’s economy; leads to tragic tsunami as well.

Seismic wave is one kind of energy waves that naturally exist in an earthquake. It dramatically shakes the ground surface in vertical and horizontal when it passes over. It causes serious destruction and directly affects to local people’s life. Once earthquake occurs, the buildings, bridges, dams, art monuments…which are not specially constructed will collapse; people cannot escape from these structures will be perished under the destruction. For a tremendous earthquake about 7 to 8 Richter, thousands of people are killed; cities are in ruin; millions are homeless because of the shaking. Viewing the city after a quake, we see nothing but the fallen houses, the death and the cracking ground. Shaking also leads to the pollution. The air is covered with a blanket of dust; rivers and lakes are stuffed up with full of broken brick, garbage…Living in this condition, people will catch many diseases. All of these affect directly to human life.

Beside the destruction and bad effects on human life, earthquake also makes the nation’s economy get stuff. For agriculture, all crops and harvest will be destroyed; broken dams cause floods and wash away all agricultural produce. For industry, factories, companies, workshops, headquarters… collapse. All the remain is the destruction, so they cannot produce or manufacture anything. Moreover, the government spends all budgets to aid people first after that they rebuild these structures. However, it is not easy for a country has just passed over an earthquake to rebuild the economy in a short term; it even takes 20 to 50 years to keep up with the state of itself before the quake. In 20 to 50 years, global economy has new development, so that country hardly can keep pace with others in the world. In general, like other disasters earthquake badly affects to nation’s economy.

Once an earthquake happens, it can lead to other disasters; the most dangerous one is the tsunami. The quake often occurs in the depth of the oceans, and when it happens, it releases the seismic wave. This wave travels more slowly in the liquid than it does on the ground surface, so when it is in the ocean, it seems to be harmless though it is traveling in the speed of light. As soon as reaching the coast side, it makes giant waves like high and long wall of water and devastates coastal regions. The tsunami even causes more destruction than the earthquake. Although being the consequence of the earthquake, the tsunami does not always occur. People do not pay much attention to its alert signals, and the result appears very serious. For example, threatening tsunami in Japan, Indonesia, Nicaragua in 1992 which occurred at night without any alert signals destroyed and devastated all the local communities.

In conclusion, earthquake destroys structures, kills people; affects directly to nation’s economy; leads to more tragic disaster_Tsunami. We cannot avoid the destruction, but we can reduce it by designing special buildings that can stay long with the shaking, and equipping the tsunami alert system in the coastal regions.

Kinds of people

Living in society, we have to contact many people in different characters. Have you ever wonder why this person has short temper while the other is very calm?. The answer is the differences in our psychology. Each of us is unique with our psychology characteristic, so how many kinds of people among billions in this society? Basing on researches of many psychologists, although we are different, we still have some characteristics relate to one in four disposition that is also the basic for us to classify people into four kinds_ short temper, calm, melancholy, active.

The first kind is short temper people also known as the man of moods. Due to the influence of the hot disposition that has more occupation of enthusiasm than inhibition people in this type tend to show up all their emotion whenever they feel happy or angry. Short temper people is specialized by living openly with others; working actively and confidently; thinking and doing what they think; like challenging themselves … Besides those strong points, the weakness like too hurry when doing something; envious and fond of surpassing others; impatient and easy to give up when facing with difficulties are still exist. Truong phi that is a character in Tam Quoc Dien Nghia novel is a symbolic example of short temper people. He never thinks thoroughly before doing something; believes that everything can be solved by physical power. People in this kind interact well with new environment, but they are easy to lose temper; cannot do important work.

Calm people is the second type. Like the name, people belong to this kind are very calm because of the balance between the enthusiasm and the inhibition. They hardly show their emotion or feelings; it is difficult to guess what they think even looking into their eyes. Well consider before doing something; carefully acting; cleverly controlling the situation are features of this kind. They are absolutely opposite to short temper people. If you had read Tam Quoc Dien Nghia novel before, you can immediately recognize that Quan Vu belongs to calm people type. Basing on those previous features, we can conclude people in this kind are suitable for jobs need strong standpoint, managing and controlling skills.

Another kind that is equivalent with the weak disposition is melancholy people. In the weak disposition, the rate of both enthusiasm and inhibition is very low, so we often feel the anxiety, worried, sadness in their eyes; the tiredness covers all their face. They have soft voice, silently live separate others; do not want to have too much relationship. That lifestyle lead them think a lot, passive with the change of the environment, cannot stand being under pressure and easy stressed.

The last one is the active people. By the affection of flexible disposition, people in this kind are very voluble and vivacious. They think and absorb deeply from the root of the problem; have many new ideas; live and work in new environment easily; like widening relationship; make friend easily. However, sometimes they tend to be very hasty and hurry when doing something; self-conceited; put themselves over others. Active people is suitable for jobs require the diplomacy.

Four kinds of disposition stand for four kinds of people_ short temper, calm, melancholy and active. Inside each person does not only have one kind of disposition, but that is the combination of many kinds in which has one kind surpassing others. The disposition that has more affection on people is the strong foundation of people classifying system.
