🚨 SHISHALDIN VOLCANO ALERT RAISED – AUGUST 25, 2025 🚨 The Alaska Volcano Observatory has raised Shishaldin’s alert level to ADVISORY (YELLOW) after a surge in seismic tremors, infrasound, and sulfur dioxide gas. Steaming from the summit has intensified. These are the same signals recorded before the 2023 eruption that disrupted international flights. Shishaldin erupts with little warning. Flight paths and communities near Unimak Island are now on alert. #Shishaldin #AlaskaVolcano #VolcanoAlert
