Could Mt Rainier destroy Seattle if it erupted?

Best Answers

Although lahars cannot travel far enough to reach Seattle, there is a chance volcanic ash could. In 1980 scientists calculated that when volcanic ash (tephra) from the Mt. St. Helens eruption traveled over 100,000ft up into the sky. Mt. Rainier would be able to produce the same if not more tephra. read more

The distance is 100 km. as the crow flies. Mt. Rainier is not a super volcano so the pyroclastic flow would not reach as it did when Mt. Vesuvius exploded and buried Pompeii and Herculaneum. read more
