the aquifer collapse is caused when the porous spaces of the permeable rock are filled with air, weakening the layers of the aquifer, as water is removed during over mining.
causes buildings to collapse
Some environmental agent as to increase the underground aquifer level. Maybe too much rain.
An aquifer is an underground fresh water source.
aquifer is the correct answer
The source of an artesian well is an underground aquifer.
that will be :sinkholes
The aquifer cannot be recharged fast enough
It drives the sinking of the city by a couple of inches a year.
The over-pumping can cause sinkholes and/or collapse of the availability of fresh water. In the worst case polluted water can be drawn into the area of the pumps.

An artesian aquifer is a confined aquifer containing groundwater under positive pressure. This causes the water level in a well to rise to a point where hydrostatic equilibrium has been reached. A well drilled into such an aquifer is called an artesian well.
Colony collapse is when bees mysteriously disappear. Vampire mites and nicotine-based insecticides are among the possible causes.
Causes of collapse for which rescue breathing may be needed are anaphylactic shock, heart attack, and poisoning.

The collapse of a star is based on its age. When it runs out of "Fuel" its inside contracts as the outside expands. it can then super nova or collapse into a tiny star.
