Vestrahorn Mountain, Iceland

This is excellent photograph!! Next one is Katla;

"Katla (Icelandic pronunciation: [ˈkʰahtla] (About this soundlisten)) is a large volcano in southern Iceland. It is very active; twenty eruptions have been documented between 930 and 1918, at intervals of 20–90 years. It has not erupted violently for 101 years, although there may have been small eruptions that did not break the ice cover, including ones in 1955, 1999, and 2011.

Prior eruptions have had a Volcanic Explosivity Index (VEI) of between 4 and 6 on a scale of 0 to 8. In comparison, the Eyjafjallajökull 2010 eruption had a VEI of 4. Bigger VEI-5 eruptions are comparable to Mount Pinatubo's 1991 eruption, while significantly rarer VEI-6 eruptions would be comparable to Krakatoa's 1883 eruption.

Katla is one of the largest volcanic sources of carbon dioxide (CO2) on Earth, accounting for up to 4% of total global volcanic carbon dioxide emissions." Wikipedia
