NASA confirms the alert with a satellite image: a U.S. volcano has enormous seismic activity and is “on the verge of erupting”
NASA has recently captured a satellite image of a volcano in Alaska, showcasing huge potential for volcanic activity.
NASA has recently captured a satellite image of Iliamna Volcano in Alaska, highlighting its disturbing potential for volcanic activity.
The image, taken on June 10, 2025, by the Operational Land Imager (OLI) aboard the satellite Landsat 8, shows the glacier-covered peak that sits around 130 miles southwest of Anchorage - Alaska’s largest city.
Despite its last recorded eruption occurring in 1876, the volcano has experienced more recent seismic activity that has subsequently been linked to avalanches in the region, as the magma-filled mountain shakes off its white coat.

Disaster potential behind recent rumblings ‘remains uncertain’
As recently as June 15, 2025, seismic activity at Iliamna Volcano intensified, with almost continuous tremors recorded by the Alaska Volcano Observatory (AVO).
These seismic signals are reminiscent of those preceding significant avalanches, such as those in May 2016 and June 2019, which involved rapid ice and rock slides descending the volcano’s slopes. However, everything remains quiet at the time of writing.
The AVO released a statement calming fears: “An increase in seismicity, marked by frequent small earthquakes, has been observed at Iliamna Volcano beginning at about 4:30 am AKDT (12:30 UTC), June 15, 2025. This activity is likely not caused by volcanic unrest.”
“The seismic activity resembles that previously observed preceding large ice and rock avalanches at the volcano, although the outcome of the current activity remains uncertain. Large ice and rock avalanches at Iliamna Volcano in the past have often occurred around this time of year,” it added.

Scientists continue to monitor the volcano closely for any further activity, as giving the civilian population the longest possible time to evacuate should the priority for everyone in the region.
