| Caption: | Eruption of lava at Pavlof captured in this WorldView-3 short-wave infrared false color image from January 19, 2022. An active lava flow is erupting from a vent on the eastern flank of the volcano and extending 1.3 km east. Meltwater from interaction between the lava and snow and ice is then producing lahars that extend beyond the lava flow up to 4.4 km east from the vent. |

| Caption: | Eruption of lava at Pavlof captured in this WorldView-3 image from January 19, 2022. In this look into the active east vent, a scoria cone is building up inside the crater, partially obscured by steam. The currently active lava flow is spilling out on the southern side of a delta of older lava flows. The active channel is incandescent in this visible light image. Minor tephra deposits are also visible, darkening the snow. |

| Caption: | Eruption of lava at Pavlof captured in this WorldView-3 image from January 19, 2022. A scoria cone is visible and steaming in a vent on the eastern flank of the volcano. An active lava flow is spilling out, extending 1.3 km east. Meltwater from interaction between the lava and snow and ice is then producing lahars that extend beyond the lava flow up to 4.4 km east from the vent. Minor ash deposits are also visible as dark streaks on the snow emanating from near the front of the lava flow, where steam generation is likely producing weak explosive activity. |

| Caption: | WorldView-3 satellite imagery from December 19, 2021 shows the current eruption in the summit region of Pavlof Volcano. The east vent is active, sending a lava flow down the eastern flank. A tephra deposit from explosive activity on December 14, 2021 is also visible on the northeastern flank of the volcano. Older deposits from 2021 and the 2016 vent are labeled. |
