Is volcanic activity common in Iceland?
As a result of being in a unique setting where a continental rift and a magma plume join forces, Iceland is one of Earth’s most volcanically active areas. On average, Iceland experiences a volcanic event every four years.
Is Iceland volcano a threat?
Iceland’s volcanoes like to throw the European air traffic network into chaos. Given many volcanoes lay under glaciers, an eruption can cause the glacier to melt often resulting in large volumes of melt water rushing towards roads, homes and out to the ocean. But it can also result in another associated hazard.
What causes the volcanic activity in Iceland?
The reason that there are so many volcanoes in Iceland is that the country lies where two tectonic plates meet. Basically, the tectonic plates are large pieces of the Earth’s crust in the layer called the lithosphere. Since these plates are not fused, extremely hot substances are able to rise from within.
