## 根因

干沟和冲沟会集中辐射热，引导火焰，并可能产生火旋；它们还会滞留烟雾，导致窒息，且无法防护余烬雨。

## 解决方案

1. ```
   If trapped, find a large, non-vegetated area (e.g., a parking lot or bare rock face) and lie face-down, covering your body with a wool blanket or jacket. Call 911 and provide GPS coordinates.
   ```
2. ```
   Pre-evacuate when a wildfire warning is issued. Use the 'Watch Duty' app for real-time fire perimeter updates. Do not wait for a direct order.
   ```

## 无效尝试

- **** — Assuming that being below ground level shields from heat; radiant heat can still be lethal from nearby flames. (70% 失败率)
- **** — Believing that dry vegetation in a ditch won't burn; embers can ignite it instantly. (55% 失败率)
