In Vietnam, one of the most common natural disasters is flooding. Flooding occurs frequently, especially during the rainy season, which typically lasts from May to November. Heavy rains and overflowing rivers often lead to widespread flooding, affecting both urban and rural areas. Before a flood occurs, it is essential to take preventive measures such as reinforcing homes, securing belongings, and evacuating to safer areas if necessary. After a flood, immediate actions should be taken to ensure safety, such as avoiding contaminated water, seeking medical attention if needed, and cleaning up debris. Additionally, communities should work together to rebuild and strengthen infrastructure to mitigate the impact of future floods.
