Landslides ( 山体滑坡 ) occur when large amounts of wet debris ( 碎片 ), including rocks, earth, and trees, slide down a slope ( 斜 坡 ). They may occur as a result of fires, earthquakes, volcanic eruptions, storms, or human activities. Landslides are particularly dangerous because they strike suddenly, move at extremely high speeds, and travel long distances. Although landslides are often difficult to predict, you can prepare for a landslide by following proper safety rules, ensure that you’re familiar with the warning signs, and making an emergency plan.
Become familiar with the land around where you live and work so that you understand your risk in different situations.
Learn about local emergency response plans.
Stay alert and awake in danger. Many deaths from landslides occur while people are sleeping.
Listen for unusual sounds that might indicate moving debris, such as trees cracking ( 爆裂声 ). If you are near a stream or river, be watchful for any sudden increase or decrease in water flow and notice whether the water changes from clear to muddy. Such changes may mean there is debris flow activity upstream, so be prepared to move quickly.
Listen to local news stations on a battery-powered radio for warnings of heavy rainfall.
Consider leaving if it is safe to do so.
If you suspect a danger, evacuate ( 撤退) immediately. Inform your neighbours if you can, and contact your public works, fire or police department.
Be especially alert when driving-watch for collapsed pavement, mud, fallen rocks and other indications of possible debris flow.
Talk to everyone in your family what to do if a landslide occurs. Create and practise an evacuation plan for your family and your business.
