Root Cause

Landslides can be triggered by earthquakes, volcanic activity, snowmelt, or human activity (excavation, blasting) days or weeks after rainfall, and this advice creates false security.

generic

中文

山体滑坡可由地震、火山活动、融雪或人类活动（挖掘、爆破）在降雨后数天或数周触发，该建议造成虚假安全感。

Workarounds

  1. 90% success Monitor USGS landslide alerts and local geological surveys for real-time hazard assessments, not just rainfall data.

  2. 85% success Inspect for warning signs (cracks, tilting trees, unusual water flow) regularly, regardless of weather.

中文步骤

  1. 监控USGS山体滑坡警报和当地地质调查的实时灾害评估，而不仅仅是降雨数据。
  2. 无论天气如何，定期检查警示迹象（裂缝、树木倾斜、异常水流）。

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Monitoring only weather forecasts; seismic activity or construction vibrations can trigger landslides without rain.

  2. 75% fail

    Assuming that a dry period means safety; slow-moving landslides can fail days later due to delayed water infiltration.

  3. 90% fail

    Ignoring cracks or bulges in the ground as non-urgent without rain; these are precursors to imminent failure.
