Table 2 The warning levels of creeping landslide in Zigui County.
From: Analysis of rainfall response and graded warning for landslides
Warning level | Stage of deformation | Disaster occurrence situation | Defense measures | Continuous rainfall for n days(mm) |
|---|---|---|---|---|
1–2 | Basically no deformation or minimal deformation | Small possibility | Not taking measures or paying attention to the monitoring of disaster points | 0–78.3 |
3 | Slow deformation | Medium possibility | Initiate group measurement and prevention work at disaster risk points, reminding people in the disaster area to pay attention to the dynamics of the disaster | 78.3–160.1 |
4 | Constant velocity deformation or brief acceleration deformation | Greater possibility | Strengthen monitoring of disaster points and implement preventive emergency measures for disaster risk areas | 160.1–196.6 |
5 | Accelerate deformation to failure | Maximum possibility | Monitor hidden danger points, organize emergency evacuation routes and disaster relief systems | > 196.6 |
