Today I do not see only the news about the earthquake of Lorca in local newspapers. I also see it at the BBC main page.
It seems that the earthquake that happened some months ago was related or induced by the extraction of groundwater during years.
It seems that the water level had descended about 250 meters.
I have always wondered how water is kept below earth. Is it mixed with earth as mud. Or are there kind of caves keeping the water? I say that because when you see water in a well it seems to me something a bit strange. What are we really having at the bottom of the well? It is a kind of lake? Is there air there below us?
