Watching the explosions from Stromboli’s summit craters is highly hypnotic and addictive. Try to concentrate on the colours of the lava emitted in the form of scraps. Right at the point of emission it has a very intense yellow colour, nearing white. This yellow then gradually gets darker until it turns orange, then red when the lapilli are a little further away from the mouth of the volcano. This is an effect of the gradual lowering of the lava temperature as it moves away from its point of emission.
