Un filmato dell'eruzione e una serie di domande-risposte tratte da un articolo di LUCA MERCALLI :
A quale quota si trova il pulviscolo?
Il pulviscolo viaggia intorno ai 4 mila metri e rischiamo di non accorgerci del suo passaggio ad alta quota
Si annebbierà il sole?
In molti forse si aspettavano di veder transitare un oscuro strato di polveri in grado di annebbiare il sole, ma in realtà, se non avessimo appreso dalle cronache che tremila chilometri più a Nord-Ovest era in corso un’imponente eruzione, and if there were no problems to air traffic, virtually from the ground we would not have noticed anything.
Why was blocked air traffic?
planes would risk serious damage when crossing the cloud of suspended particles, the grinding of the windscreen to stop the engines. So, rightly, all still on the ground.
What is the situation in the Alps?
tools MeteoSwiss Last night marked the passage of the ashes over the Alps, initially at about 6000 meters, while the hazy morning, the plume has slowly dropped to around 4000 meters, so that he could also catch a cable car going up on the snow Plateau Rosa, Cervinia above. And today the volcanic dust will continue their journey south, affecting even by tomorrow south-central Italy, even if further diluted, excluding probably Sicily.
The ashes will settle to the ground?
The volcanic ash - tiny fragments of rocks and minerals - they tend to settle very slowly to the ground under the influence of their weight or, more quickly, in case they become incorporated into the rainfall. It 'so important not only to predict the direction of the winds, but also the weather conditions that might favor or not the permanence of airborne dust at high altitudes.
What will happen in the coming days? According to volcanologists
eruption in progress will continue to throw ash into the atmosphere ... but fortunately the ash emitted by ' Eyjafjallajokull are not dangerous to health.
