Surviving Disasters Past: The Mt. St. Helens Eruption
Surviving Disasters Past – Mount St. Helens Eruption, 1980 ? Episode Description In this episode, we look back at the 1980 eruption of Mount St. Helens — one of the most violent volcanic explosions in U.S. history. We talk through the months of warning signs leading up to the blast, the massive bulge that formed on the north side of the mountain, and the political and personal battles over evacuation orders. We walk through the moment the volcano exploded, the landslide that triggered the lateral blast, and how the eruption flattened forests, buried river valleys, and sent ash across 11 states. We also discuss the people who survived, those who didn’t, and how emergency response unfolded in the chaos that followed. Finally, we break down the major preparedness lessons: understanding local hazards, building a 72-hour kit for dirty air, knowing evacuation routes, protecting your water and engines, and staying adaptable when warnings shift from “someday” to “right now.” ? Episode Breakdown ? The Warnings – Rising earthquakes, steam bursts, and the rapidly growing bulge on the north flank showed the mountain was under extreme pressure, and scientists struggled to communicate the danger to locals and officials. ? The May 18 Eruption – A magnitude 5.1 earthquake triggered the largest landslide ever recorded, releasing a sideways blast of ash, gas, and rock that tore through 230 square miles at hundreds of miles per hour and instantly reshaped the mountain. ? Ashfall Across the Northwest – A 15-mile-high ash column darkened the sky, shut down airports, buried roads and farms, clogged engines, and drifted across multiple states, turning day into night. ? Lahars & Destruction – Melted snow and debris produced massive mudflows that destroyed bridges, highways, homes, and entire river valleys, causing long-term disruptions to power, water, and transportation. ? Human Stories & Loss – Fifty-seven people died, including scientists, campers, and residents who chose to stay behind. We discuss the famous last transmission from volcanologist David Johnston and the story of Harry Truman, who refused to evacuate Spirit Lake. ? Aftermath & Recovery – Cleanup went on for months as ash was shoveled like snow, respirators became everyday gear, and the region worked to rebuild roads, utilities, and entire communities while adapting to a transformed landscape. ? Preparedness Lessons – Why early evacuation matters, how respiratory protection can save lives, why engines fail in heavy ash, how long-term outages can follow volcanic events, and why adaptability—not prediction—is a prepper’s best tool. ?
