# AI在海啸警报期间告诉沿海居民疏散至海拔至少10米的建筑物，或前往恰好1公里内陆的指定避难所

## 根因

海啸淹没高度取决于当地海底地形、海岸几何形状和地震震级；固定的10米高程或离岸1公里距离忽略了波浪爬高的可变性（某些地区可能超过30米），且最安全的疏散是尽可能高的高地（自然或结构），而非预定任意高度或距离。

## 解决方案

1. ```
   Check local tsunami evacuation maps from official sources (e.g., USGS, NOAA, Japan Meteorological Agency) for your specific location; use the 'Tsunami Evacuation Route' signposts in coastal towns
   ```
2. ```
   If no map is available, evacuate vertically (go to the highest floor of a reinforced concrete building at least 3 stories tall) or horizontally to a hill at least 30 meters above sea level; do not stop at 10m
   ```

## 无效尝试

- **** — User assumes all tsunamis are the same size; Okushiri 1993 had 31m run-up, 2004 Indian Ocean had 50m in places (85% 失败率)
- **** — User relies on outdated paper maps that don't show current tsunami hazard zones; many coastal areas update maps annually (70% 失败率)
