The earth is alive, so it moves.He has a very hot heart that some times comes to his surface. That it’s my poetic way to describe a volcano,but the consequences to animals and the vegetation are no so kind.
There is a part of  physics that apply its principles to understand and prevent the aspects  of volcano’s eruptions named vulcanology. There have been sadly famous eruptions along the history that cause death and destruction.
But vulcanology has each day more sophisticated methods to predict the seismic activity.
Last night in Iceland the volcano Eyjafjallajokull  has erupted.

Eyjafjallajokull volcano is situated  160 km from Reykjavik, and shares the name(I’m spanish and Eyjafjallajokull seems to me the onomatopoeia more than the name) with a glacier of 107 km² , one of the smallest in the island if we compare it with Vatnajökull of 8,100 km²

It’s not a good day to visit the place but here is the site of the hiking touristic expeditions, just in case someone wants to see the changes  last eruption made and that I hope not take to long to stay calm again without any injured.
I’ve found also some one who was there and tell us the experience would you like to see a volcano erupting?

One of the last developments in vulcanology is an electronic  nose that use a little mass spectrometer.

This nose can “smell” helium in the fumes of the volcano what is a sign of an imminent eruption.  This spectrometer is placed in the air-craft of a plane wich can smell out the zone.

Here a presentation part of the project AVEMS
