Floods are a common natural disaster in Vietnam. The main reason is that humans cause environmental damage, making the earth warm. They occur when water from heavy rains, melting snow, or water overflows through rivers, lakes, and other bodies of water that cover normally dry land. Flooding can cause enormous damage, including the destruction of homes and infrastructure, as well as loss of life. Flooding can also cause secondary hazards such as landslides, fires, and waterborne diseases. To stop this, the government is finding new modern solutions and giving precautions with warnings as soon as possible. Individuals and communities need to be prepared, stay informed, and take action to protect themselves and their loved ones in the event of a flood.
