Yes, wwh. Many things can adversely affect the geology of an area when man steps in and builds what he will.

Take China for instance and the huge dam that's being built.

I read in a book recently that when dams are put it, the weight of the water in the dam, if large enough, can cause earthquakes. No joke. Within the tectonic plate itself, the weight of that extra water can cause a quake. I would think China would be most especially susceptible to earthquakes--and this huge dam with its enormous amount of extra water weight could cause one of these quakes. Not to even mention what such a dam will do to the water tables there.

There's a specific term for earthquakes that occur within the tectonic plate--but I've forgotten the term. Inter-tectonic quake...or something like that. Maybe someone here knows the term.
