Core Viewpoint - The article emphasizes the importance of understanding the characteristics and warning signs of mountain floods and landslides, as well as the necessary safety measures to take in case of such natural disasters [1][4][9]. Group 1: Mountain Floods - Mountain floods are sudden and characterized by concentrated water flow, high speed, and strong destructive power, often occurring in low-lying areas near mountain streams [2]. - Warning signs of mountain floods include hearing a rumbling sound similar to a train, which may indicate upstream flooding, and a sudden change in water clarity from clear to muddy [4]. - In the event of a mountain flood, individuals should quickly move to higher ground, avoid fleeing downstream, and seek help from emergency services if surrounded by water [8]. Group 2: Landslides - Landslides occur when soil or rock layers slide down a slope due to factors such as river erosion, rainfall, earthquakes, or human activities [9]. - Warning signs of landslides include unusual sounds, cracks in the ground, and changes in vegetation [10]. - If caught in a landslide, individuals should hold onto sturdy objects, seek shelter under solid structures, and avoid entering the disaster area immediately after the event [12][13]. Group 3: Driving Safety - During rainy conditions, it is advised not to park near loose soil slopes or hazardous areas, and to drive cautiously on outer edges of roads to avoid landslide risks [15]. - If a vehicle encounters a landslide, drivers should turn back or find alternative routes, and if trapped in a tunnel, they should park safely and activate emergency lights [15]. Group 4: General Safety Tips - It is crucial to stay updated on weather forecasts and mountain flood warnings, and to avoid mountainous areas during heavy rain [18]. - Individuals in mountainous regions should keep a safe distance from riverbanks and be aware of hazard signs and evacuation routes [18].
