The volcano has Eyjafjöll walk halfway around the world in the last week. No one had expected. The geological events are difficult to predict. Indeed not. They are easily predictable. A volcano will erupt sooner or later. A seismic zone sooner or later will be affected by an earthquake. The forecast is easy. What is difficult to predict when this will happen. In fact, even when it is not so difficult to predict. Indeed, for geologists, it is quite easy. Why then so much discomfort? The unpredictability, in humans, arises from the difference between the geological time scale in relation to a human timescale. Abitutati We are thinking in terms of years, months, days, hours, minutes. Gaia did not this time. It 's a middle-aged lady who has about 4.6 billion years and maybe 4-5 other campers billion. Not on this scale is difficult to predict when a volcano will erupt or whether there will be an earthquake. It 's impossible to predict the time, at least with the resources we have now. It will always be so? It is not known. The only sure thing is that geologic events can be or can have disastrous consequences very large, as in the case dell'impronunciabile Icelandic volcano (more to the laziness of journalists to overt impronunciabilità the name of the volcano, Iceland, someone will call with their name because they have so many volcanoes, or exchange a post- it as written?). The fact is that millions of people were walking and it has cost the airlines hundreds of millions of euro.
Once again nature shows us how small we are and how little we know. Arrogance
epistemic you have been warned.
