Iceland hotspot
Notable eruptions have included that of Eldgjá, a fissure of Katla, in 934 (the world's largest basaltic eruption ever witnessed), and Laki in 1783 (the world's second largest). In many places, Iceland is covered by glaciers. Several eruptions under ice caps have burst through the ice. The most recent one was in 2010 after the eruption of Eyjafjallajökull.
