火山爆发
作为最好的候选人，我被委派为一个数据库收集和评估各种自然灾害的信息，例如飓风、台风或雷暴等。
有时我通过向经历过这些灾害的人分发调查问卷来收集信息，有时却得亲自经历实际的灾害。
Musaki火山就是其中之一。
那时，我和一名来欣赏火山爆发的小说家同住在火山边上的一座平房里。
有一天，当我正在阳台上画图表而他在屋里洗澡时，火山突然爆发了。
喷射到天空中的火山灰和岩浆喷泉从50米到100米不等。
这一情景绝对地奇异，我甚至还注意到一条彩虹出现在热浪造成的雾里。
然而，向四周看了一下我们的处境，我马上预见到了潜在的危险，也发现了我们的安全毫无保障。
令人不舒服的气体几乎使我们失去知觉，忧虑的汗水开始流淌下来。
我们努力使自己不要惊慌和颤抖，迅速穿上保护套装、头盔和靴子，最后成功前往安全的地方。
尽管我珍贵的设备和文件都烧得精光，但是我们真的非常幸运。
