根因分析

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。

English

Lava tube entrances are unstable, can collapse under seismic shaking, and are prone to toxic gas accumulation (CO2 and SO2) that is heavier than air, causing asphyxiation.

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

常见但无效的做法:

  1. 85% 失败

    Thinking that the cave blocks radiant heat; lava tubes can radiate heat from the walls and floor, causing burns.

  2. 80% 失败

    Assuming that the cave is sealed from ash; ash can enter and accumulate, causing respiratory distress.

  3. 90% 失败

    Believing that the cave is safe from pyroclastic flows; these flows can enter caves and incinerate occupants.
