The Volcano Nobody Can Fully Watch: What Alaska's Quietest Mountain Is Really Telling Scientists

An Alaska volcano that hasn't erupted in about 570,000 years just showed signs of life. Earthquakes and gas readings pointed to magma moving beneath it. Then scientists lowered its alert level to a label that doesn't mean safe: "unassigned." Why? And what does it reveal about a bigger blind spot in how we monitor volcanoes? In this video: What Kupreanof did this year, month by month, and what scientists could and couldn't see Why Alaska has about 140 active volcanoes, more than every other U.S. state combined The 1989 Redoubt eruption, when a jet lost all four engines in an ash cloud What "unassigned" really means, and how to read a volcano alert level Why under-monitored volcanoes matter for aviation and global cargo What Alaska's volcano observatory still uses to watch remote peaks Sources: Alaska Volcano Observatory and USGS notices, Congressional Research Service report on Alaska's active volcanoes, Alaska Beacon reporting, and published research on AVO forecasting.
