Mount Rainier is behaving about as it has over the last half-million years, so all evidence suggests that the volcano will continue to erupt, grow, and collapse.
What will happen if Mount Rainier erupts?
Mount Rainier's next eruption might be of similar or larger size and could produce volcanic ash, lava flows, and avalanches of intensely hot rock and volcanic gases, called "pyroclastic flows." … Airborne plumes of volcanic ash can greatly endanger aircraft in flight and seriously disrupt aviation operations.
Is Mt Rainier growing?
Around 500,000 years ago, Mount Rainier started to grow atop the eroded remains of an earlier ancestral Mount Rainier that was active 1-2 million years ago. The modern edifice grew as a series of four alternating stages of volcanic activity, averaging a little more than 100,000 years duration.
What cities would be affected if Mt Rainier erupted?
“A mudflow from Mount Rainier is the most catastrophic natural disaster that could happen to this area,” Geoff Clayton, a geologist in Washington, explained to Seattle Weekly, stating that a lahar would “wipe out Enumclaw, Kent, Auburn, and most of Renton, if not all of it,” on its way towards Seattle.
Is Rainier an active volcano?

Will Yellowstone erupt?
Yellowstone is not overdue for an eruption. Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. … In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago. This comes out to an average of about 725,000 years between eruptions.
Will Mt Baker erupt again?
Mount Baker is presently not showing signs of renewed magmatic activity, but it will surely become restless again. Future magmatic eruptions at Mount Baker are likely to be preceded by changes at the volcano that could be detected by modern volcano-monitoring techniques.
