aðalfrumurnar

Aðalfrumurnar is a volcanic complex located in the Öraefajökull region of Iceland. It is situated in the western part of the country's Vatnajökull National Park.

Aðalfrumurnar complex includes a crater lake, Þórsarbunga, and Búrfell, a subglacial volcano. The complex's most recent eruption occurred in 1724, resulting in the formation of a new tephra cone, Þórsarbunga. The volcano is classified as a subglacial shield volcano, and it has been characterized by mildly explosive eruptions.

Aðalfrumurnar's eruptions are known for producing white-gray ejecta. The volcano's location beneath Vatnajökull, Europe's largest ice cap, makes it an unusual case study in volcanic studies. Eruptions are often accompanied by ashfall and jökulhlaups, which are glacial outburst floods caused by the melting of the glacier due to volcanic heat.

Seismic activity at Aðalfrumurnar has been monitored starting from 2009. The Öraefajökull region is known for its glacier-influenced behavior. Several glaciers surround the complex, while the interaction between the volcano and the glacier determines the eruptive dynamics at Aðalfrumurnar. Geological studies have been conducted to better understand the relationship between volcanic activity, meltwater, and the hydrology of the surrounding area.

Research at Aðalfrumurnar aims to contribute to the understanding of volcano-gla- cier dynamics, a relatively under-researched field in international volcanology. Aðalfrumurnar is considered a relatively rare type of volcano, offering insights into the complex interactions between volcanoes and glaciers. Studies in this area can provide new knowledge on the monitoring and eruption prediction of similar volcanoes around the world.
