根因分析

火山碎屑流速度超过100公里/小时，沿地形向下流动并进入山谷；如果火山口在上方，向山上跑可能进入碎屑流路径，且人类速度无法逃脱。

English

Pyroclastic flows move at speeds exceeding 100 km/h and follow topography, flowing downhill and into valleys; running uphill may lead into the flow's path if the vent is above, and human speed cannot outrun the flow.

解决方案

  1. 垂直于流动路径（侧向）撤离，并前往预期流动通道外的高地。使用官方危险地图了解安全区域。
  2. 如果无法撤离，在坚固建筑的上层避难，远离门窗，用厚毯子或湿布遮盖以保护免受热和灰烬伤害。
  3. 碎屑流过后，不要立即离开避难所；等待官方解除警报，因为可能发生二次流动和火山灰沉降。

无效尝试

常见但无效的做法:

  1. 90% 失败

    Pyroclastic flows can surge over ridges and travel far from the vent; running without knowing the flow's path often leads into its path.

  2. 85% 失败

    Pyroclastic flows can bury structures under meters of hot ash and rock, causing entrapment and asphyxiation.

  3. 95% 失败

    The flow's heat (up to 1000°C) and gas will overcome any shelter; rocks offer no protection from the blast and heat.
