Volcanoes in Iceland

Iceland sits on the Mid-Atlantic Ridge where tectonic plates diverge, creating one of the most volcanically active regions on Earth. Around 30 volcanic systems are considered active, producing eruptions approximately every 3–4 years on average. Volcanic activity shapes Iceland's landscape — from black sand beaches created by explosive eruptions to vast lava fields that cover large parts of the country.

The country is home to more than 130 volcanoes and around 30 active volcanic systems. These volcanoes have created Iceland's dramatic landscapes — vast lava fields, black sand deserts, geothermal areas, and glacial valleys carved by volcanic floods.

Many of Iceland's most famous volcanoes are subglacial — hidden beneath massive glaciers like Vatnajökull and Mýrdalsjökull. When these volcanoes erupt, they melt enormous volumes of ice, creating sudden catastrophic floods called jökulhlaups.

Eruptions in Iceland can affect the entire world. The 2010 Eyjafjallajökull eruption disrupted European air travel for weeks, while the 1783 Laki eruption caused famines and crop failures across Europe and may have contributed to the French Revolution.
