Eruptions

There were 3 vulcano eruptions in the Westman Islands, first is Helgafell or Holy mountain then Surtsey and last Eldfell (in Heimaey).

Eldfell 1973 (Fire mountain)

Eldfell is a cinder cone volcano just over 200 meters high. The eruption started in the early hours of the morning of 23 January 1973 without warning, and lasted until 3 July.
Nearly one-third of all the homes and buildings (nearly 400) had burned or been covered under the lava and ash.
After the eruption, the landscape was drastically changed. Lava covered the oldest part of the town and the size of the island had increased by more than 2.2 sq km. The lava field covers a total area of about 3,3 sq km.
Eldfell is the youngest (newest) volcano in the world.

Volcano is still heating that people can bake a bread in it.

Surtsey 1963

The volcanic eruption began 130 meters below sea level, and reached the surface on 14 November 1963 when it was observed by seaman. The eruption lasted until 5 June 1967, when the island reached its maximum size of 2.7 sq km.
This newest island in the world was named after the fire god Surtr from Norse mythology

Helgafell (Holy mountain)

Helgafell is an inactive volcano, whose last eruption was 6000 years ago. Next to Helgafell lies the active volcano Eldfell, whose last eruption was in 1973.
According to myth, the god Odin will grant three wishes to anyone climbing Helgafell for the first time, as long as they climb in silence and come down on the east side without looking back.
