NASA has raised alarms regarding Iliamna volcano, located in Alaska, indicating that an eruption could be imminent after over a century of inactivity.
Recent satellite imagery, particularly from the Landsat 8 satellite, has revealed concerning changes, especially in the glacier that caps the summit of the volcano.
Rising seismic activity is alarming as the Alaska Volcano Observatory (AVO) has detected nearly constant tremors since June 15, 2025.
Iliamna, which stands tall at about 10,016 feet, is situated in Kenai Fjords National Park, approximately 210 km southwest of Anchorage.
Despite the fact that no confirmed eruptions have occurred since 1876, scientists have noted that the volcano has not been completely dormant during this period.
The recent signs of potential unrest come as a surprise given its long history of inactivity. The combination of the glacier, seasonal melting, and the underlying magma activity makes it a complex site for prediction.
Past events, such as avalanches recorded in May 2016 and June 2019, echo concerns over how the current situation might unfold.
The AVO has exercised caution in its assessment, stating that although the frequency of earthquakes has increased, there is currently no definitive evidence indicating an upcoming eruption.
Experts suggest that the observed seismic activity could very well be attributed to seasonal melting, a common occurrence during this time of year.
Yet, despite lacking evacuation orders, the proximity of Iliamna to Anchorage results in heightened concern over any volcanic activity.
An eruption, regardless of its size, has the potential to significantly impact the lives of thousands, leading to potential disruptions in local ecosystems similar to the recent events witnessed on La Palma Island in Spain.
The uniqueness of Iliamna stems from its interaction of glaciers, potential magma movements, and its under-researched history—factors that complicate predictions and analyses.
Experts stress the importance of continuous monitoring through satellite technology and seismic sensors to ascertain whether there is a real threat to nearby populations.
Preparation is key, and residents are advised to remain informed and calm.
An emergency kit is crucial and should include water, non-perishable food, a flashlight, a radio, and masks.
It’s vital for families to review their evacuation plans and be familiar with the routes they would take should an evacuation be necessary.
Additionally, protecting important documents and avoiding proximity to the volcano during any signs of steam or ash emissions is highly recommended.
Going forward, the scientific community remains vigilant in monitoring Iliamna volcano.
Should activity escalate or other indicators appear—such as gas emissions, ground deformations, or unusual patterns—authorities will take appropriate measures to safeguard the community.
At this time, while nothing can be definitively confirmed, the focus remains on surveillance and preparation, prioritizing the safety and well-being of local residents.
