What is a Sinkhole?

A sinkhole is a commonly circular hole, depression, or opening in the ground that serves as a drain for water and surface material into the subsurface. It can result from gradual subsidence and will either form a depression in the ground or collapse to form an sudden break in the soil.

Sinkholes range in varius sizes and depths. Sinkholes in Pennsylvania happen where there are voids present in the limestone or dolomite rock beneath the soil. The voids were formed over a long period of time; as the rock was dissolved away by rain or groundwater passing through small openings, causing them to grow larger.

What Causes a Sinkhole in Pittsburgh Pennsylvania?

Weathering or dissolved minerals in the rock, that leaves residue, opens spaces within the rock.
Water washes away the soil from the voids in the rock.
When groundwater levels drop, it can cause a loss of support for the soft material in the rock spaces that can lead to collapse.
Changing groundwater gradients (due to removing or introducing water to the system) can cause loose material to wash out more quickly from the voids and the surface to collapse.
Changes like adding more water in or taking it out causes the system to become at least temporarily unstable and can lead to sinkholes.
Sinkholes can result from seasonal changes in the groundwater table like freeze and thaw and extremes in rainfall.
