- **修复率:** 88%

## 根因

熔岩管入口不稳定，在地震震动下可能坍塌，且容易积聚比空气重的有毒气体（CO2和SO2），导致窒息。

## 解决方案

1. ```
   撤离到距火山至少10公里的指定避难所，最好是有密封HVAC系统的建筑物。
   ```
2. ```
   如果被困户外，使用N95口罩或湿布过滤火山灰，并移动到远离气体聚集山谷的高地。
   ```

## 无效尝试

- **** — Thinking that the cave blocks radiant heat; lava tubes can radiate heat from the walls and floor, causing burns. (85% 失败率)
- **** — Assuming that the cave is sealed from ash; ash can enter and accumulate, causing respiratory distress. (80% 失败率)
- **** — Believing that the cave is safe from pyroclastic flows; these flows can enter caves and incinerate occupants. (90% 失败率)
