Sinkhole in Daisetta, Texas
Collapse sinkhole in a salt dome in Daisetta, Texas (September 2008). Salt is particularly susceptible to rapid dissolution causing large bowl-shaped sinkholes. Injection of fluids into this salt dome increased the dissolution of the salt causing a 60-foot deep sinkhole that covered several acres and destroyed many buildings.
