The volcano remains restless. The seismic activity continues to be elevated and no significant change in activity has occurred since the last update.
The volcano persistently emits magmatic gases from a fumarole field on the south crater and commonly exhibits low-level seismic activity. These observations suggest the presence of shallow magma and potential interaction with a hydrothermal system. The current increase in seismicity likely reflects a change to the magmatic-hydrothermal system, but it is not clear that the likelihood of a volcanic eruption has increased. The Alaska Volcano Observatory (AVO) will continue to monitor activity to determine if the recent changes are related to influx of new magma or other changes to the magma system.
