Last weekend in Hawaii, showed us the devastating consequences of a volcano erupting and lava spewing out of the volcano Kilauea a dormant concern to most of us until we see this happen even though volcanic activity is the object of constant study and analysis how close are we to these seeming sleeping time bombs.
The last volcano to erupt in Spain was a volcano 7 km south-west of La Restinga occupying the southern part of the island of El Hierro in the Canary islands in 1971 and recently an underwater eruption in 2012.
Volcán El Cerro de Agras (confrentes) the only volcano in the Valencian community rises to the altitude of 527 meters to the summit and said to have educational and scientific value. Last known eruption was in the Pleistocene geologic time period 2.58 million years ago.
The Volcano releases CO2 (carbon dioxide) and CH4 (methanol), through a magma chamber, which is a large pool of liquid rock beneath the surface of the Earth. Gas bubbles expel into the Hervideros spring giving the impression the water is boiling creating a natural spar.
In the midst of the lava flowing out of the volcano Kilauea, Hawaii, green gemstones were sighted these are known as olivine, this green mineral is also found at El Cerro de Agras.
