总是很难理解作者的意图。但对我来说,“雨热灰”听起来不像一个火山碎屑流,而是像一个火山灰秋天,这是一个不同的火山灾害。“火缓慢的河流”似乎更明显,可能指的熔岩流。与其他火山灾害相比,火山灰和熔岩流很少杀死。看到例如*火山灾害和事件:一个新的数据库* ([Witham 2005] [1])。278341年有一个编译volcano-related死于1600年,按火山灾害(表15)。熔岩仅占总数的0.56%,而类别火山灰/弹道占5.02%。熔岩很少杀死,因为它是缓慢的。有某些情况下快速熔岩,致命的,像[1977山尼拉贡戈火山的喷发][2]。但托尔金说,河流的“慢”,所以我们可以排除这种风险可能致命的主角。 Tephra falls mostly kill by roof collapse: when a thick layer of tephra accumulate on a roof, it will eventually collapse, killing the people inside. This is what killed most victims during the [1991 eruption of Mount Pinatubo][3]. So, as long as the protagonists stay outside, they should also be safe from this hazard.
