20 West Coast Geological Events You Need to Know: Tsunami & Ash Risk

Earth is moving beneath North America's most monitored regions. 🌋

We explore 20 key geological developments across the West Coast, Yellowstone, and the Cascade Range — covering:
• The Cascadia Subduction Zone & San Andreas Fault
• Earthquake swarms & ground deformation
• Active volcanoes (Mt. Rainier, Mt. St. Helens, Mt. Hood & Mt. Baker)
• Hydrothermal activity at Yellowstone (including the Biscuit Basin event)

Note: Activity remains at normal background levels, but scientists are closely tracking every shift for signs of change.
