Context: A volcano in Southwest Iceland erupted after weeks of intense earthquake activity.
Volcano Eruption in Iceland
- The volcano that erupted, is located in Reykjanes peninsula in Iceland.
- Iceland is among the most volcanically active places in the world, with roughly one eruption in every five years, not including submarine eruptions.
Why does Iceland have so many volcanoes?
- Geolocation:
- Iceland is located on the Mid-Atlantic Ridge, which separates the North American and Eurasian tectonic plates.
- These tectonic plates are detached one from another allowing magma to fill the space that is created which results in the creation of one or more volcanic systems
- Iceland is located on a hotspot or mantle plume, where magma is especially close to the surface, leading to frequent volcanic eruptions.
- Types of Volcano: The most common type of volcano in Island is stratovolcano — cone-shaped peak with explosive eruptions that form a crater in the very top.
- Geography: Iceland’s entire surface is made of volcanic rock, most of it is basalt that formed after cooling of the volcanic lava.
