No. A pot hole is usually just an eruption of the pavement itself.
A sink hole is generally caused by nature, when natural limestone beneath the surface of the ground becomes saturated with water and starts to condense and collapse, bringing the ground with it.
A ground collapse is usually considered a sink hole that is caused by overdevelopment on top of limestone, and poor management of water retention ponds, or leaks in drainage pipes that cause that disintegration of the limestone.
In other words - "sink hole" usually refers to a natural occurrence, and parts of Florida are prone to it since most of Florida is built on sand and limestone. Ground collapses usually refer to a contruction-caused occurrence.
The two are sometimes used interchangeably, but that tends to just confuse matters - and sometimes confusing matters is intentional to shift blame.
