Why the United States closely monitors these 8 volcanoes
Why These Volcanoes Are Watched So CloselyThe United States hosts more than 160 potentially active volcanoes, primarily concentrated in Alaska, the Pacific Northwest, California, and Hawaii. Many of them sit near populated areas, critical infrastructure, major air routes, and vital ecosystems. The U.S. Geological Survey (USGS) classifies volcanoes by threat level, considering factors such as eruption history, proximity to communities, and potential hazards including ashfall, lava flows, lahars, landslides, and volcanic gases.Among them, eight volcanoes stand out as the most closely monitored due to their high hazard potential and complex behavior. Advanced monitoring networks—including seismic stations, GPS sensors, satellite imagery,…
