What has happened is a collapse of the caprock overlying the Daisetta salt dome. Caprock is comprised of mostly very porous limestone that is easily fractured by the excessive pressures caused by the salt water disposal company that injects waste salt water from oilfields into the caprock. When such high pressures are used in their operation, the caprock freaks apart (fractures) and gives way and the overlying surface sediments fall into the hole, leaving a surface crater.
This disposal operation is regulated by the RRC of Texas. So, this was NOT a collapse of the actual salt dome at all - merely a collapse of the overlying limestone. This is similar to what is well known to happen in Florida in the "karst" areas.
