There are many types of natural disaster such as: forest fire, mudslide, tsunami, vocanic eruption,...but I think, earthquake is one of the most types of pollution. On $27^{th}$ February in 2010, an earthquake about $8,8^{0}$ richter happened in Chile. The land seemed to be violently shaken. People began running as walls started to collapse. All homes, trees and animals were sinked in ruins. Hundreds of people were injured and died. The rest had to take a shelter to protect themselves. Rescue workers digged the ruins to find the victims. After the earthquake had happened, millions of people had to sleep on the street without food and drink and face with poverty. Fortunately, the government have sent food, fresh water, money and medical supplies to the victims. They have also consoled people and planned to prevent earthquake in this area by building basements to provide accomodation for everyone.

Among natural disasters in Vietnam, storms and floods are one of the most devastating natural disasters, often occurring in the northern and central coastal provinces. There are about 10 storms in the South China Sea, of which about 4-6 storms hit the coast of Vietnam. Over the years, Vietnam has been directly affected by many storms. Storms often cause water to rise in coastal areas. Over the past 30 years, up to half of storms have hit Vietnam, causing water levels to rise above 1m and 11% of storms causing sea levels to rise above 2m. In very exceptional cases, storms can reach several meters. In some coastal areas storms generate waves and shorten the coastline. As a result, high tides cause water to overflow to the mainland. The storm has caused great damage to fishermen at sea, destroyed aquaculture establishments, destroyed the system of dykes to prevent salinity, brought salt water into rice fields and coastal residential areas. sea. Strong storms also cause damage to homes, structures, fruit trees and crops. It has caused a lot of damage to people and property. Crop failure due to floods. People became homeless and lost all their possessions. And many other damages caused by the storm. To prevent and fight storms, before it happens, we have to build dykes, fully prepare tools, food and necessities, so we regularly listen to the latest news about floods, strengthening our homes. . When there is a storm, people must find a safe place to shelter, not go out. Then we have to overcome devastating storms like rebuilding houses, and many other things, if we live in that area, we should plant trees, protect the environment and many other practical things.
