Caption:	Sentinel-2 acquired a clear view of the Veniaminof caldera on February 23, showing that minor steam emissions continue at the cone but there are now no steam sources coming from the cooling lava flow margins. The 2018 lavas are still relatively snow-free.

Veniaminof

Caption:	A Sentinel-2 image of Cleveland from February 22 shows a small steam plum rising from the summit, which is otherwise shrouded in clouds. This is consistent with other satellite observations of no dome growth but continued steaming.

Caption:	Sentinel-2 view of Great Sitkin acquired at 22:49 UTC on January 9, 2019. The visible (left) and short-wave infrared (SWIR) false color (right) images show a very small steam plume emanating from the central crater, accompanied by SWIR anomalies.

Great Sitkin

Caption:	Landsat 8 image of the aftermath of the Cleveland explosion on January 9, 2019. The satellite image was acquired at 22:11 UTC, just three hours after the explosion at 19:15 UTC. A small steam plume and tephra deposit are apparent in visible imagery (left), and the crater is hot in the short-wave infrared (SWIR) bands (right, pan-sharpened false color). The small deposit is consistent with the geophysical evidence for the small size of the explosion.

Caption:	Sentinel-2 satellite image of Veniaminof volcano acquired Dec. 5, 2018. Three lava flow lobes are evident in the image with relative ages 1 (oldest) and 3 (youngest). AVO became aware of flow 3 on Nov. 29, 2018. It is uncertain when this flow first formed as the volcano was obscured by clouds for some time prior to Nov. 29.
