Volcanos Valencia Spain

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.

Cofrentes town is of Roman origin, and located 103 km south-west of Valencia on the N-330 towards Requena. After crossing the bridge over the Cabriel River and ascending a slope, you should be able to follow the signs. It takes 1 h 34 min (138.2 km) via A-31 and N-330 from Alicante.

CO2 Crisis how did it happen?

Panicked victuallers are rushing to Tesco supermarket to stock up on cider and beer cans in the wake of the recent CO2 (carbon dioxide) shortage at a crucial time for bars as summer and the televised world cup bring in much-needed punters and a higher demand for soft drinks and alcohol. The question on most people's lips: why has this happened?

The manufacturing process involves farmers releasing ammonia from fertilizer and intern capturing CO2 gas, a by-product, which will be sold commercially to the food and drinks industry. Natural gas is a key raw material in the production of ammonia and is at a high price at the moment limiting production in Europe.

Farmers in summer use less fertilizer so plants closed down for either routine planned maintenance or critical repairs and upgrades. This year in the UK and across Europe too many plants have closed down at the same time causing this current crisis.

The UK suffered the most closures leaving only one plant operating. CO2 gas is difficult and expensive to transport so food and drink producers would rather buy off local distributors. Pubs were told by suppliers next week's orders will be short and it's not clear how long this will go on for but contingency plans are being put in place to keep up production using less carbon dioxide.

Equally, packaged foods are effected by the shortage of CO2; they will be given a shorter shelf life affecting the length of time they'll be left on shelves before being consumed. Producers will utilise replacement gases which are used in the vacuum-packing process for meat, poultry, cheese, salads, ready meals etc., to preserve them.

One of the UK's largest plants, now shut down, is expected to run again next week.
