What is Eyjafjallajökull?

According to Wikipedia, Eyjafjallajökull is a volcano that is completely covered by an ice cap. It covers 100 square kilometers or 40 square miles. The mountain is a stratovolcano, but that means it’s an opening volcano in a planet’s surface, which lets hot magma, volcanic ash and gases escape from below the surface. The volcano is tall, at the highest point it stands 1,651 meters or 5,417 feet. It is built up by many layers. It is built from hardened lava, tephra, pumice and volcanic ash. Most of the eruptions are quiet, but explosive.

Eyjafjallajökull is fed by a magma chamber that is under the mountain. It gets the magma from the Mid-Atlantic Ridge that is the part of a chain of volcanoes stretching across Iceland. Scientists say that one day this chain will cut Iceland in two parts. They say it separates a little bit every year.  We have more volcanoes on this volcanic chain and the name of the neighbors are Katla, Eldfell and Heimaey. Scientists say that eruptions of Eyjafjallajökull have generally be followed by eruptions in the other mountain, Katla.
