The three major types of sinkholes know to us are
Solution, Cover Collapse and Cover Subsidence
.
What is the difference between the cover subsidence sinkhole from the cover collapse sinkhole?
In areas where cover material is thicker, or sediments contain more clay, cover-subsidence sinkholes are relatively uncommon, are smaller, and may go undetected for long periods. Cover-collapse sinkholes may
develop abruptly
(over a period of hours) and cause catastrophic damages.
