Mount Edgecumbe, a long-quiet volcano in Southeast Alaska just across the sound from the city of Sitka, began inflating in the summer of 2018. This activity, coupled with increased seismicity near the volcano, drew lots of interest to the area.

What was happening at Mount Edgecumbe? To gain a better understanding of what’s going on beneath the volcano, a team of researchers set out to explore heat and gas emissions in the Mount Edgecumbe volcanic field in the summer of 2023. This information can help us monitor any activity at the volcano and better understand this volcanic system below the surface. Join me to learn what we found there this past summer.
