Eyjafjallajökull

Eyjafjallajökull (; "glacier of (the mountain) Eyjafjöll"), sometimes referred to by the numeronym E15, is one of the smaller ice caps of Iceland, north of Skógar and west of Mýrdalsjökull. The ice cap covers the caldera of a volcano with a summit elevation of . The volcano has erupted relatively frequently since the Last Glacial Period, most recently in 2010, when, although relatively small for a volcanic eruption, it caused enormous disruption to air travel across northern and western Europe for a week.

==Geography== Eyjafjallajökull consists of a volcano completely covered by an ice cap. The retreating ice cap covered an area of in 2019, but was previously more than , with many outlet glaciers. The main outlet glaciers are to the north: Gígjökull, flowing into Lónið, and Steinsholtsjökull, flowing into Steinsholtslón. In 1967, there was a massive landslide on the Steinsholtsjökull glacial tongue. On 16 January 1967 at 13:47:55 there was an explosion on the glacier. It can be timed because the seismometers at Kirkjubæjarklaustur monitored the movement. When about of material hit the glacier a massive amount of air, ice, and water began to move out from under the glacier into the lagoon at the foot of the glacier.
