Mount Rainier is an Active Volcano
Volcano scientists are watching and studying Mount Rainier for signs of a future eruption. Although it is not showing signs that it will erupt anytime soon, Mount Rainier is considered an active volcano.
The biggest hazard to people is from lahars (volcanic mudslides) that can happen even without an eruption. Communities around the mountain practice safety drills for a lahar, much like many communities do for tornadoes and earthquakes.
Earthquakes are one thing that scientists study to looks for signs of an eruption.
Mineral spring, lava ridges, and fumaroles are all volcanic features present at Mount Rainier.
