Vesuvius IN SIGHT OF SCIENTIFIC
The Vesuvius, whose last eruption occurred in 1944 could revert to pop like when he destroyed Pompeii in 79 AD Only this time probably wipe out some 700,000 people.
To find out if such a catastrophic situation could materialize, it is very important that the magma stored at 8 to 9 kilometers deep, is appropriately named. It according to researchers who have analyzed the samples produced by the ascent of magma chambers under Vesuvius, for more than 20,000 years.
If this magma was similar to the Pompeii eruption occurred, you can expect in the future eruption "highly explosive" in the assessment of experts " Institute of Earth Sciences " of Orleans ( Institut des Sciences de la Terre d'Orléans "ISTO - Université d'Orléans ) in France .
However, if I had a basaltic magma, as in the last eruption so far recorded, the output of lava would be like "warm", with rivers of lava, y esto generaría destrozos mucho menos importantes.
El Vesubio es un volcán muy particular. A lo largo de su historia ha tenido erupciones de tipo explosivo, tan devastadoras como la del Krakatoa que en Indonesia, devastó más de 17 islas en 1883, o la del Pinatubo, el volcán de las Filipinas, famoso por su gran erupción de 1991, alternadas con otras efusivas, de ríos de magma, como las que son comunes sobre todo en Hawai, o los volcanes de la isla de "La Reunión" también muy peligrosos.
Según los vulcanólogos, el Vesubio registró desde hace 20.000 años, hasta la gran erupción que sepultó a Pompeya, erupciones explosivas precedidas de volutas de humo y gases toxic. From 1631 to 1944, there have been hundreds of effusive eruptions associated with lava flows, as currently happens with another famous Italian volcano, Stromboli, located in the Aeolian archipelago.
But according to experts, not because these developments take 2,000 years can exclude a return to more acidic compositions, explosive eruptions can engender appalling. Scailter warns the famous, world-renowned scientist, not because it has stopped in 1944, one can say that is over.
Vesuvian eruption of 79 AD was observed in detail by Plim NIO the Elder, Roman writer renowned polygraph the famous Natural History, which more than such, is a veritable compendium on the diversity and quality of the materials involved.
In front of a Roman fleet with the rank of admiral, the scholar was to investigate the true nature of the phenomenon, since it did not accept the mythological explanations, suggesting that the volcanoes and lava were the result of the activities of Vulcan the blacksmith god who helped their workers, Cabir, and Cyclops, was throwing up the flames of Etna.
But the Roman came so that was overcome by gas fumes.
The no less famous Pliny the Younger described it brilliantly, but their accounts were dismissed as exaggerated until modern science rehabilitated him, recognizing the extraordinary value of these notes.
The historical eruption, in addition to covering Pompeii in a thick layer of ashes, destroyed by a deadly pyroclastic flow to neighboring cities such as Herculaneum and Stabia.
Those were summer resorts frequented by the Roman nobility, crystallized in the time since they were buried and well preserved.
After costly excavations, you can now walk through its streets paved with stone slabs, admire its buildings, and enjoy their villas, richly decorated with frescoes.
This set of valuable evidence of life at the time Imperial has remained exceptionally clearly.
According to scientists, the lack of activity from the volcano 65 years ago, may be due to two things: (1) On the one hand, leaving filling the bag denominadaa magma. (2) On the other hand, something truly awful, which may indicate that the chimney is blocked, ie blocked with solidified lava. If the latter were the case, the immense pressure could rise by this cap, running to generate an explosion of catastrophic type.
What really happen?
hope that scientists have an answer before nature is revealed once again.
