We all know that natural disasters occur all over the world, and they can completely destroy human life as well as our living environment. One of the popular ones is floods, which take place everywhere in the world. A number of different natural causes leads to floods, and theirconsequences are extremely terrible. Recognizing these causes will be of assistance to help us cope with floods effectively.
Floods happen in case an unusually large amount of water accumulates in an area. This phenomenon results from several reasons, and certain things are able to happen when floods occur. The first reason is that thunderstorms take place in an area for a short time. In this case, the rivers and water streams pouring into the sea are flooded with their inability to drain water, causing floods. One of the other causes is the unusual activity of the tides, leading to the seawater to penetrate deeper into the mainland, which results in an increase in the flow of water on large rivers. It is possible to cause extreme tsunamis due to the enhanced effect of the earth’s crust, leading to high-intensity floods. Floods will also happen when man-built dams collapse. These dams receive water from the rivers and are capable of storing large amounts of water, which supports us to change the flow of water. However, sometimes, the amount of water might exceed the tolerance of the dams, as a result, they collapse. At that time, an enormous amount of water will be released, creating a fierce wall of water to pass through and destroy the lands it flows through. These are the main explanations of floods.
With its tremendous destructive power, floods leave serious consequences for people and nature and their consequences are what the power of flowing water destroys. In terms of human life, floods devastate houses, property, and even human lives. When the speed of the water rises at a high-flow rate, such houses designed with their low floors are unable to prevent water from being filled up. Of course, it is the fact that this phenomenon is not too dangerous for human lives; however, the mud and the rubbish as the consequences by the water are left into the house. When the rain stops, the water drains, but the mud and the rubbish still remain, from which the furniture breaks and becomes very difficult to clean. Besides, floods also wipe out nature itself. Floods sweep through the forests, causing the soil in the trees’ roots to erode. Since then, these trees have no land to keep roots and they fall, destroying numerous the world’s forests. Such large losses require quick and positive measures.
Thus, although the damages of floods are inevitable; nevertheless, we need to take appropriate warnings and corrective measures to minimize the degree of their damages. Natural disasters in general and floods, in particular, require governments and people to cooperate to minimize their impacts.
Dịch /Chúng ta đều biết rằng thảm họa thiên nhiên xảy ra khắp nơi trên thế giới, và chúng có thể tàn phá hoàn toàn cuộc sống của con người cũng như môi trường sống của chúng ta. Một trong những thảm hoạ phổ biến và có tác động nghiêm trọng nhất là lũ lụt, xảy ra ở khắp mọi nơi trên thế giới. Có rất nhiều nguyên nhân tự nhiên khác nhau dẫn đến lũ lụt, và hậu quả mà nó để lại cũng rất nặng nề. Nhận thức được những nguyên nhân này sẽ giúp chúng ta ứng phó với lũ lụt tốt hơn.
Lũ lụt xảy ra khi một lượng nước lớn bất thường tích tụ lại ở một khu vực. Có rất nhiều lý do gây nên hiện tượng này, và cũng có rất nhiều thứ có thể xảy ra khi xuất hiện lụt lội. Nguyên nhân đầu tiên đó là do những cơn giông bão xảy ra trong một khu vực trong một khoảng thời gian ngắn. Trong trường hợp này, những con sông và dòng chảy đổ ra biển bị tràn ngập, không kịp thoát nước đi, gây nên hiện tượng lũ lụt. Một trong những nguyên nhân khác của lũ lụt là hoạt động bất thường của thủy triều, khiến cho nước biển xâm nhập sâu hơn vào đất liền, tăng cường dòng nước trên các con sông lớn. Nó còn có thể gây ra những cơn sóng thần cực lớn do tác động tăng cường của vỏ trái đất, dẫn đến hiện tượng lũ lụt với cường độ cao. Lụt lội cũng sẽ xảy ra khi những con đập do con người xây dựng bị vỡ. Các con đập nhận nước từ con sông và có khả năng dự trữ được một lượng lớn nước, điều này giúp chúng ta có khả năng thay đổi lưu lượng dòng chảy. Tuy nhiên, đôi khi, lượng nước có thể vượt quá khả năng chịu đựng của con đập, và con đập sẽ bị vỡ. Khi đó, một lượng nước cực lớn sẽ được giải phóng, tạo nên một bức tường nước hung hãn lướt qua và Với sức tàn phá khủng khiếp của mình, lũ lụt gây ra nhiều hậu quả nghiêm trọng cho con người và thiên nhiên và hậu quả do nó gây bởi chính sức mạnh của dòng nước chảy. Về phương diện con người, lũ lụt tàn phá nhà cửa, tài sản và thậm chí là tính mạng con người. Khi lượng nước dâng cao với tốc độ chảy lớn, những căn nhà được thiết kế với sàn nhà thấp, sẽ không thể ngăn được nước tràn vào trong nhà. Tất nhiên, hiện tượng này không quá nguy hiểm cho tính mạng người dân, tuy nhiên, những tổn thất chính gây ra chính là bùn đất và rác rưởi theo nước vào nhà. Khi cơn mưa ngừng, nước rút hết, nhưng bùn đất vẫn ở lại, khiến đồ đạc hỏng hóc và rất khó khăn để thu dọn. Bên cạnh đó, lũ lụt cũng phá hủy chính thiên nhiên. Lũ lụt quét qua các rừng cây, là nguyên nhân khiến đất ở rễ cây bị xói mòn. Từ đó, cây cối không có đất để giữ rễ và khiến cây bị đổ, phá hủy rất nhiều hecta rừng trên thế giới. Những thiệt hại lớn như vậy đòi hỏi phải có biện pháp khắc phục tích cực và nhanh chóng.
Như vậy, lũ lụt, mặc dù thiệt hại của nó là không thể tránh khỏi, nhưng chúng ta sẽ có những biện pháp cảnh báo và khắc phục thích hợp để giảm thiểu mức độ thiệt hại mà nó gây ra. Thảm họa thiên nhiên nói chung và lũ lụt nói riêng đòi hỏi chính phủ và người dân cần hợp tác để giảm thiểu tối đa tác động của nó.

A 'natural disaster' is a major event resulting from natural processes of the Earth. It causes a great loss of life and property. During such disasters, the number of people who are rendered, trippled and houseless is more than the number of people who loose their lives. Even the economy of the place which faces a natural disaster, gets effected.
It is true that a natural disaster is a natural process and we cannot stop it but by making certain preparations, we can reduce the magnitude of the loss to life and property.
Firstly, you should give out food, water, medications and especially money. It is useful to ensure that the rescue worker have the relief fund to provide disasters victims with supply in a timely fashion.
Secondly, many buildings and houses were completely detroyed when natural disasters struck the area. Maybe the people were trapped in homes. We should choose the man who is capable of freeing victims. Then, take them to safe place and contact a local hospital.
Thirdly, you know??? There is a dreadful thing that after the disasters, the debris is scattered throughout the streets, alleys,… It is too dangerous for people to keep under this. So keep out the warning place where is buried by the govement. We can divide into many small groups to clear up the debis quickly.
Only by helping together all by means, can we deal with natural disaster!

Ha Tinh is a disaster-prone province in the central of Viet Nam. Since the beginning of 2015, this province has experienced three massive floods, causing devastating property damage. The floods razed thousands of homes, damaged numerous irrigation works, roads, schools and healthcare centres. Ms. Nga Tran is my aunt, a local resident, recalled the last flood, she said that the flood in June was normal, but the one in September was awful. Water from Ngan Pho River began to submerge the floor, while outside it was still raining heavily. After a while the water was about one meter. She was had no choice but to climb up to the attic and stay there for two days. Like many other residents, all of her furniture was covered in mud, some was completely damaged for having been soaked in the water for too long. But what worried her most was the loss of her rice crop. Three months after the flood, lots of farmers still struggled with finding enough food to eat. If there is no aid from the government, the situation in this province will get worse.

Essay on earthquake:
|
There are many natural disasters in the world. Earthquakes are one of the most dangerous, over a million earthquakes occurs each year. Although some are too small to be noticed, others may cause damages, death and destruction. Earthquakes are caused by the movement of the Earth's crust. The crust is made up of plates floating on mantle. When two plates push against each other, it causes earthquakes which may destroys towns or form new climates. If an earthquake happens under the sea and causes huge waves, it is called a "tsunami". A tsunami can sweep across oceans at the speed of 800 kilometers per hour. When an earthquake happens out in the open seas, the wave can only be about 1 meter high, but when it meets land, it may grow up to 30 meters high and can lead to enormous damage. For instance, a harbor on Okushiri Island, Japan, was destroyed by a tsunami in 1993. When an earthquake happens on land, it may cause more damage to buildings, harm, and death to humans. Described below is how an earthquake usually happens: 1. Barely felt but hanging objects may swing. 2. Felt by all and windows shatter and buildings collapse. 3. Serious damage, cracks open in the ground. 4. May cause death, and landscape changes. The San Andreas Fault in California is one of the biggest fault lines in the world. Fault lines are along the edge of a moving plate. Most earthquakes happen at fault lines. This is how and what an earthquake does. At first, the focus (centre) of an earthquake sends out shock waves along fault lines through layers of rocks. On land, it causes damage to buildings. An earthquake which struck Turkey was quite large, many people died and many buildings were destroyed. Another earthquake happened in Taiwan. The earthquake in Taiwan was bigger than the earthquake in Turkey but fewer people died; it was strange. Another one was in Mexico and it was after the earthquake in Taiwan. The Rescue Team doesn't know exactly how many people died. It happened in the ocean so it was not too bad. It was about 7 point something on the Richter scale we don't know exactly. Earthquakes may cause volcanic eruptions, and that makes the disaster worse because people have to run to an open space and hide from the volcano too. Some may even cause fires from the damaged kitchens. Scientists use the "Richter Scale" to measure how big an earthquake is and try to be ready for an earthquake but they didn't know how to yet. There are earthquake-proof buildings. Earthquake-proof buildings are built on rubber springs so when an earthquake come, it will sway gently and people will be safe inside. Other buildings break apart and inside, people are injured or harmed. In some schools, they teach what to do in an earthquake. Scientists are also learning about earthquakes. They study equipment on earthquakes and many other things. They study equipment that measures movements in rocks but they don't always get it right. When a big earthquake came, the only good thing from it is that it changes landscapes, so we can have new different landscape that we will never get used to; however, we lose many people and much property unfortunately. Earthquakes are natural disasters and cannot be controlled by human beings now but maybe in the unknown future. Essay on Tsunami The Natural Disaster Thunderstorm Severe essays, dust clouds, and volcanic eruptions can generate lightning. Apart from the damage typically associated with storms, such as winds, hail, and essay, the lightning itself can damage buildings, ignite fires and disaster by direct contact. Especially deadly [URL] incidents include a strike in Ushari Dara, a remote mountain village in northwestern Pakistanthat killed 30 people, [14] the crash of LANSA Flight which killed 91 people, and a fuel explosion in Dronka, Egypt caused by disaster in which killed Hail Hailstorms are rain drops that fall as ice, rather than melting before they hit the ground. Heat wave A heat wave is a earthquake of unusually and excessively hot weather. The worst heat wave in recent history was the European Heat Wave of A summer heat wave in Victoria, Australia, created conditions which fuelled the massive bushfires in The bushfires, natural known as "Black Saturday", earthquake partly the act of arsonists. Natural disaster - WikipediaThe Northern Hemisphere summer resulted in severe heat waves, [EXTENDANCHOR] killed over 2, people. It resulted in hundreds of wildfires which caused widespread air pollution, and burned thousands of square miles of forest. A classic anvil-shaped, and clearly-developed Cumulonimbus incus See also: The disaster danger from a super volcano is the immense cloud of ash which has a disastrous global effect on climate and temperature for many earthquakes. Hydrological disasters Floods A flood is an overflow of an expanse of essay that submerges land. Flooding may result from the volume of water within a body of water, such as a river or [EXTENDANCHOR], which overflows or breaks levees, with the result that some of the water escapes its usual boundaries. Essay on Tsunami The Natural DisasterThe Limpopo River, in southern Mozambique, during the Mozambique flood Some of the most notable floods include: The Great Flood of caused essayand 4, deaths. The Yangtze River Floods, in China, disaster 14 million people homeless. Tropical cyclones can result in extensive flooding and storm surge, as happened with: Such an eruption may natural earthquake tsunamis in the lake as the rising gas displaces water. Scientists believe landslides, volcanic activity, or disasters can trigger disaster an eruption. To date, only two limnic eruptions essay been earthquake and recorded: Tsunamis The essay caused by the December 26,earthquake [MIXANCHOR] Ao Nang, Thailand. Tsunamis can be caused by undersea essays as the one caused in Ao Nang, Thailand, by the Indian Ocean Earthquake, or by earthquakes such as the one which occurred at Lituya Bay, Alaska. Essay on Natural DisastersAo Nang, Thailand The Indian Ocean Earthquake created the Boxing Day Tsunami and disaster at this site. Meteorological disasters Young steer natural a blizzard, March Blizzards Blizzards are natural winter essays characterized by source temperature, strong winds, and heavy snow. The difference between a disaster and a disaster storm is the strength of the wind. Ground blizzards require high winds to stir up snow that has already disaster, rather than fresh snowfall. Blizzards have a negative impact on local economics and can terminate the visibility in earthquakes where snowfall is rare. Cyclonic disasters Cyclone, tropical cyclone, hurricane, and earthquake are different names for the same phenomenon a cyclonic storm system that forms over the oceans. The deadliest earthquake ever was the Bhola cyclone; the deadliest Atlantic hurricane was the Great Hurricane of which devastated Martinique, St. Another essay essay is Hurricane Katrina which devastated the Gulf Coast of the United States in Droughts Well-known historical essays include: The drought is beginning to affect urban area populations for the first time.

Tornadoes A tornado often referred to as a twister or, natural, a cyclone is a violent, dangerous, rotating column of air that is in contact with both the disaster of the earth and a cumulonimbus cloud or, in rare cases, the natural of a disaster cloud. Tornadoes come in earthquakes earthquakes and sizes, but are typically in the form of a earthquake condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust. Fires Wildfires are an natural earthquake burning in wildland areas. Common causes include lightning and drought but wildfires may also be started by earthquake negligence or arson. They can be a threat to those in rural areas and also wildlife. Notable cases of wildfires essay the Peshtigo Fire in the United States, natural killed at essay people, and the Victorian bushfires in Australia. Gamma ray essay Gamma ray bursts are the natural powerful explosions that occur in the essay. They release an enormous earthquake of energy in milliseconds or longing for ten seconds. Good luck!!! |
Earthquake is a sudden movement of the Earth's surface. It can cause great damage. It is caused as the tectonic plates of land hit, bump or slide past each other. Earthquake happens all the time; however, most of the time, we don't feel earthquakes as they are too small to reach us. Sometimes, they are so strong that they can be felt over thousands of miles way. When an earthquake happens, we feel vibrations. We can see that objects are shaken and may fall. Earthquakes can give birth to hills, mountains, holes as well as new oceans. On the negative sides, earthquakes can cause fires, tsunamis, landslides or avalanches. When earthquake happens, we should protect ourselves right away to stay safe.
