Icelandic volcanism is a result of the country's unique geological position on the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates diverge. This activity leads to frequent volcanic eruptions, with Iceland being home to around 30 active volcanic systems. The eruptions can produce various types of lava, ash, and gases, significantly shaping the landscape. The most famous volcanoes in Iceland include Eyjafjallajökull, which erupted in 2010, and Katla, known for its powerful eruptions. The volcanic activity also contributes to the formation of geothermal energy, making Iceland a leader in renewable energy production.
