Veniaminof volcano in Alaska frequently erupts with little to no detectable precursory ground movement or seismic activity. A new study analyzing the 2018 eruption with thermomechanical models demonstrates that eruptions can occur with minimal warning when deep, low-flux magma systems are surrounded by thermally softened rock.
Low-level ash emissions from the summit of Veniaminof volcano, Alaska were observed in web camera views on April 5, 2021, the Alaska Volcano Observatory (AVO) reported at 20:49 UTC. Because of the renewed activity, AVO has raised the Aviation Color Code to ORANGE…
The Alaska Volcano Observatory (AVO) has raised the Volcano Alert Level to Watch and the Aviation Color Code to Orange for Veniaminof volcano at 18:04 UTC on March 4, 2021. The last time this volcano erupted was in 2018 (VEI 1). According to Volcano Observatory…
Over the past several days there have been periods of seismic tremor and occasional earthquakes at Veniaminof volcano, forcing the Alaska Volcano Observatory (AVO) to raise the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory. The volcano has a…
The Alaska Volcano Observatory (AVO) raised alerts for Veniaminof volcano after pilot reports of steaming coincided with low-level tremor recorded at the volcano at 20:30 UTC (12:30 AKDT). These observations mark a departure from recent background activity – the…
Ash emissions at Veniaminof volcano increased significantly on November 21, 2018, forcing Alaska Volcano Observatory to raise the Aviation Color Code to Red and Volcano Alert Level to Warning. Veniaminof is generating a plume of ash up to 4.6 km (15 000 feet) above…
Veniaminof volcano continues to erupt, feeding a lava flow confined to the ice-filled summit caldera, the Alaska Volcano Observatory reports. The last known eruption of this volcano took place in 2013. While no significant ash emissions were observed, elevated…
The Alaska Volcano Observatory (AVO) has raised the Aviation Color Code to Orange and the Volcano Alert Level to Watch for Veniaminof volcano at 21:29 UTC on September 4, 2018. The last known eruption of this volcano took place in 2013. The decision to raise alerts…
Alaska Volcano Observatory (AVO) reported that eruption of Veniaminof resumed on October 6, 2013. An aerial view of the volcano today, October 7, showed a gray-brown ash column rising from the active vent. White water vapor clouds seen on the image below are…
Increased seismicity, characterized by elevated levels of continuous tremor, lava fountaining, and ash emissions as high as 4.5 – 6 km (15,000 to 20,000 feet) above sea level have been occurring at Veniaminof volcano, Alaska, on the morning of August 30th. Latest AVO
