Deformation that results from pressurization of a "Mogi" source model

Detailed Description

Cross section through the Earth showing the ground surface with an embedded pressure source (red circle)—the so-called “Mogi model”—beneath the ground.  When this pressure source expands, the ground surface inflates like a balloon (the opposite occurs when the pressure in the source decreases).  Dashed black line shows, in an exaggerated way, how the shape the surface changes in response to the pressurization of the Mogi source.
