the earth is just like that. Our theory has been verified by actual observation in many places. It has been known to happen that an earthquake has continued until the wind that caused it burst through the earth into the air and appeared visibly like a hurricane. This happened lately near Heracleia in Pontus and some time past at the island Hiera, one of the group called the Aeolian islands. Here a portion of the earth swelled up and a lump like a mound rose with a noise: finally it burst, and a great wind came out of it and threw up live cinders and ashes which buried the neighbouring town of Lipara and reached some of the towns in Italy. The spot where this eruption occurred is still to be seen.
Indeed,Belstaff Lea Jackor, this must be recognized as the cause of the fire that is generated in the earth: the air is first broken up in small particles and then the wind is beaten about and so catches fire.
A phenomenon in these islands affords further evidence of the fact that winds move below the surface of the earth,Air Jordan Retro 11 Damskie. When a south wind is going to blow there is a premonitory indication: a sound is heard in the places from which the eruptions issue. This is because the sea is being pushed on from a distance and its advance thrusts back into the earth the wind that was issuing from it. The reason why there is a noise and no earthquake is that the underground spaces are so extensive in proportion to the quantity of the air that is being driven on that the wind slips away into the void beyond.
Again, our theory is supported by the facts that the sun appears hazy and is darkened in the absence of clouds,Dame Moncler Cachalot Norge Salg, and that there is sometimes calm and sharp frost before earthquakes at sunrise. The sun is necessarily obscured and darkened when the evaporation which dissolves and rarefies the air begins to withdraw into the earth. The calm, too,Belstaff Knockhill Jackor, and the cold towards sunrise and dawn follow from the theory. The calm we have already explained. There must as a rule be calm because the wind flows back into the earth: again, it must be most marked before the more violent earthquakes,Canada Goose Chilliwack Bomber, for when the wind is not part outside earth, part inside, but moves in a single body, its strength must be greater. The cold comes because the evaporation which is naturally and essentially hot enters the earth. (Wind is not recognized to be hot,Belstaff Racemaster Blouson Jackor, because it sets the air in motion, and that is full of a quantity of cold vapour. It is the same with the breath we blow from our mouth: close by it is warm,Chaussures Nike Air Max TN VIII, as it is when we breathe out through the mouth, but there is so little of it that it is scarcely noticed,PJS Herreklær Harraseeket Parkas, whereas at a distance it is cold for the same reason as wind.) Well,Ralph Lauren Ned Västar, when this evaporation disappears into the earth the vaporous exhalation concentrates and causes cold in any place in which this disappearance occurs.
A sign which sometimes precedes earthquakes can be explained in the same way. Either by day or a little after sunset,Maillot Aguero Pas Cher, in fine weather, a little, light,Cameroun Pas Cher, long-drawn cloud is seen,CG Menn Ontario Parka Norge Salg, like a long very straight line. This is because the wind is leaving the air and dyin
