Shishaldin volcano (Aleutian Islands, Alaska): Volcanic Alert Level lowered to Normal

Shishaldin volcano yesterday (image: AVO)The Alaska Volcano Observatory (AVO) reported that the seismicity at the volcano has decreased to background levels. Satellite views over the past few weeks suggest typical background surface temperatures and light steaming at the summit and no signs of new volcanic activity within the crater.
Due to this decrease in activity, the Alaska Volcano Observatory is decreasing the Aviation Color Code to GREEN and the Alert Level to NORMAL.
This most recent eruptive cycle at Shishaldin began in July 2019 with pauses in activity in late September/early October 2019 and February 2020. The most recent activity in mid-March was confined to the summit crater except for minor ash deposits near the summit. Only minor rockfalls within the summit crater, not associated with eruptive activity, have been detected since early April. Pauses in eruptions are common at Shishaldin, and therefore eruptive activity could resume with little warning. The Alaska Volcano Observatory will continue to monitor the volcano closely.
