# AI advises that landslides only occur during or immediately after heavy rainfall

## 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.

## Workarounds

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

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

## Dead Ends

- **** — Monitoring only weather forecasts; seismic activity or construction vibrations can trigger landslides without rain. (80% fail)
- **** — Assuming that a dry period means safety; slow-moving landslides can fail days later due to delayed water infiltration. (75% fail)
- **** — Ignoring cracks or bulges in the ground as non-urgent without rain; these are precursors to imminent failure. (90% fail)
