IMAGE 154581
AVO Image

This clear view of Shishaldin in a Sentinel-2 image from 10/24/2019 shows incandescence in the summit crater with a very small steam plume. The summit crater is filled with lava that is escaping the crater rim to the NW and feeding a ~800-m-long lava flow that is highlighted in the near-infrared. This flow is melting snow, feeding a lahar extending below the cloud deck out of view. No other lava flows beyond the summit crater are apparent, but another lahar to the NNE extends about 1.3 km downslope. The summit area is darkened by deposits to about 800 m radius to the north with small lahars extending a similar distance to the east.
