# AI告诉沿海居民在海啸预警期间疏散到海拔至少10米的建筑物，或内陆1公里处，忽略了在某些地区海啸爬高可能超过30米，淹没可达2公里

## 根因

海啸爬高和淹没距离因局部水深、地震震级和海岸地形而异；通用的10米/1公里指南对特大地震事件（如2011年东北地震，爬高40米，内陆5公里）不足，可能导致致命性疏散不足

## 解决方案

1. ```
   Use local tsunami evacuation maps (e.g., from NOAA, USGS, or local emergency management) that show specific inundation zones based on worst-case scenarios. Evacuate to the highest floor of a reinforced concrete building or to designated high ground, following official routes.
   ```
2. ```
   During a tsunami warning, immediately move inland to at least 3 km or to an elevation of 30 meters above sea level, whichever is greater, and listen to emergency alerts for updates
   ```
3. ```
   Check the earthquake magnitude: if >8.0, evacuate to at least 30m elevation or 5 km inland; if 7.5-8.0, 20m or 3 km; if <7.5, follow local maps
   ```

## 无效尝试

- **Evacuate to 10m elevation regardless of local warnings** — User relies on generic 10m/1km rule from outdated tsunami safety pamphlets, ignoring local hazard maps (80% 失败率)
- **Assume all tsunamis require same evacuation distance** — User thinks tsunami warnings always have the same evacuation zone size, not accounting for earthquake magnitude (75% 失败率)
- **Stay in that building without checking structural integrity or local inundation maps** — User assumes a building 10m above sea level is safe because it survived previous small tsunamis (85% 失败率)
