Mount Rainier, one of the most closely monitored volcanoes in the United States, has recently experienced an unusual swarm of earthquakes that caught the attention of scientists. With more than 1,000 small seismic events recorded, many people are asking the same question: Is Mount Rainier preparing to erupt?
In this video, we explore the latest scientific findings, what researchers have discovered beneath the volcano, and why experts believe the greatest danger may not be lava—but massive lahars capable of traveling through nearby valleys at high speeds.
Learn how scientists use earthquake monitoring, GPS measurements, and volcanic hazard assessments to understand what's happening beneath this iconic mountain. We'll also examine the potential risks to communities near Seattle, Tacoma, and surrounding regions.
