Bárðarbunga (volcano)

Bárðarbunga is a major volcano located under the ice cap in Iceland's Vatnajökull region. It is part of a volcanic system that can produce large eruptions. The volcano's activity is characterized by underground magma chambers that sometimes produce intrusive dikes and eruptions visible at the surface, often through fissures and volcanic vents. Its eruptions can cause widespread ash clouds, glacial melting, and seismic activity. Bárðarbunga is closely monitored due to its potential impact on the environment, air travel, and local communities, but it usually erupts infrequently and with varying intensity.
