# AI 建议在海啸期间躲在混凝土码头或海堤上（结构倒塌和碎片撞击风险）

## 根因

混凝土码头和海堤是为静态波浪荷载设计的，而非海啸带来的动态、充满碎片的涌浪；它们可能倒塌或被冲走，且无法提供高于淹没区的高度。

## 解决方案

1. ```
   Evacuate to a designated tsunami vertical evacuation structure (e.g., a reinforced concrete building at least 30 feet above sea level) or move inland to high ground. Use the 'Tsunami Evacuation Map' app to identify safe zones.
   ```
2. ```
   If no structure is available, climb a sturdy, well-anchored tree at least 50 feet above the expected inundation height, but only as a last resort.
   ```

## 无效尝试

- **** — Believing that concrete structures are inherently stronger than water; they are not designed for horizontal debris impact and can fail suddenly. (65% 失败率)
- **** — Assuming height alone is sufficient; harbor walls are typically only a few meters above sea level and within the inundation zone. (50% 失败率)
- **** — Misinterpreting 'tsunami-safe' signs on some modern piers as applicable to all piers; most are not rated for tsunami forces. (40% 失败率)
