El Hierro Volcano: Is one of the Smallest of the Canary Islands, the origins of the Island date back some 100 million years when the Ocean floor shifted with the movement of the Earth's mantle. The crust cracked into a three pointed star releasing flows of Magma.

After 3 Eruptions, the island emerged from the ocean as an imposing volcano more than 2,000 Meters high.

It has now been over 200 years since the last Eruption but El Hierro although being the smallest Island has the Largest number of Volcanoes with over 500 open Sky Cones and another 300 covered by the most recent outflows.

There has been uncertainty surrounding reports of a historical eruption taking place in 1793.
