Mount Erebus, located in Antarctica, last erupted on December 26, 2021. This ongoing volcanic activity is characterized by a persistent lava lake and regular explosive eruptions, making it one of the most active volcanoes in the world.
The volcano has exhibited continuous eruptions for several decades, and its eruptive history includes both explosive and effusive phases. Eruptions often result from the interaction of magma with water and ice, which is prevalent in its polar environment. Observations and monitoring are crucial as such eruptions can have implications not only for the local environment but also for air travel due to ash clouds.
