Mount Rainier Earthquake Swarm Breaks Records - Scientists Issued RED ALERT!

In this video, we investigate Mount Rainier’s record-breaking earthquake swarm that began on July 8, 2025—more than 1,350 quakes, the largest ever detected at the volcano. We explain why scientists believe the swarm was driven mainly by hydrothermal pressure and steam-fluid movement, not clear signs of rising magma. We break down how the USGS analyzed quake depth, waveforms, and deformation data, and why key eruption red flags (inflation, abnormal gases, heat spikes) did not appear.
Finally, we connect the swarm to real-world hazards—especially lahars, landslides, and glacier-linked risks—and what the event means for monitoring and preparedness across nearby valleys.
