雷尼尔火山因远古泥流风险对塔科马和西雅图南部构成威胁。 Mount Rainier volcano poses threat to Tacoma and South Seattle due to ancient mudflow risks.
雷尼尔山是华盛顿州的一座休眠火山，已经 1000 年没有喷发过了，但它对塔科马和南西雅图的潜在影响让美国火山学家夜不能寐，这两个地方都位于以前火山喷发留下的 100 英尺厚的古老泥流之上。 Mount Rainier, a dormant volcano in Washington state, has not erupted in 1,000 years, but concerns its potential impact on Tacoma and South Seattle, which lie on 100-foot-thick ancient mudflows from previous eruptions, are keeping US volcanologists up at night. 危险并不在于炽热的熔岩流，而在于火山可能释放出致命的泥流和碎屑。 The danger lies not in fiery lava flows but in the volcano's potential to release deadly mudflows and debris.
