One natural disaster that often happens in Vietnam’s mountainous areas is a landslide. It usually happens during the rainy season, from June to October, when heavy rain makes the soil soft and weak. Landslides can destroy houses, roads, and farms. Before a landslide, people should avoid steep areas and listen to weather warnings. They should also prepare emergency supplies like food, water, and medicine. After a landslide, people should help rescue others and clean up the area. The government and rescue teams often provide support. With good preparation, we can reduce the damage from landslides.
