南方今年以来最强降雨来了！警惕这些地质灾害

Core Viewpoint - The southern region of China is expected to experience the strongest rainfall of the year from May 27 to 29, with a high risk of heavy rain disasters due to the overlap with previous rainfall areas [1][34]. Group 1: Potential Geological Disasters - Strong rainfall may lead to geological disasters such as landslides, mudslides, ground subsidence, and fissures [4][34]. - Areas at high risk for geological disasters include steep slopes, valleys, and regions with mining activities or previous geological incidents [8][34]. Group 2: Signs Before Geological Disasters - Signs of impending geological disasters include muddy water in streams, movement at the foot of slopes, and unusual animal behavior [11][14]. - Specific signs for landslides include the appearance of cracks, sudden changes in water levels, and tilting trees [15][16]. - For collapses, signs include expanding cracks and falling rocks, while mudslides may be indicated by sudden changes in river flow and unusual sounds [20][22]. - Ground subsidence may be preceded by sudden changes in water levels and the appearance of circular cracks [23][34]. Group 3: Emergency Preparedness and Response - Residents should prepare emergency supplies and maintain communication tools before heavy rainfall [27][32]. - In the event of a landslide, mudslide, or collapse, individuals should evacuate quickly to higher ground and avoid low-lying areas [28][30]. - It is advised to minimize outdoor activities and carry a long pole when walking to avoid hazards like missing manhole covers [31][34].
