Geological map of Iceland
Geological map of Iceland. Map of Iceland showing a number of geological features including volcanoes, glaciers and eruptive fissures. Iceland lies on the Mid-Atlantic Ridge, the spreading boundary between the North American and Eurasian plates, and has been formed by successive eruptions of volcanic rock. The map is colour-coded according to when the volcanic rock was laid down.

Iceland, satellite image. Located in the Atlantic Ocean, just below the Arctic Circle, Iceland is a sparsely populated country of around 300, 000 people and an area of 100, 000 square kilometres. Its capital, Reykjavic, is at the head of the promontory to lower left. The large glacier at centre right is known as the Vatnajokull glacier.

Volcanic lightning, Iceland, April 2010
Volcanic lightning. Time-exposure image of lightning in and around a large ash column produced during the 2010 Eyjafjallajokull volcanic eruptions. Volcanic lightning is the release of electric charge that builds up as rising ash mixes with the atmosphere. The activity under the Eyjafjallajokull glacier started in March, with a major eruption taking place on 14 April, sending ash high into the atmosphere. Carried by the wind, this ash led to the closure of large parts of European airspace for several days. This is a relatively long time-exposure image, taken on 18 April 2010.
