My comment: Salt domes were formed many years ago. Man has dug out the middle of the domes leaving huge empty caverns. Think of it as an upside down U, underground.

This salt dome cavern appears to me to have filled up with water and the top of the dome near ground level has collapsed forming this sinkhole.

Other reports claim that nearby 'sister' caverns filled with butane, might be effected by this neighbor dome that is transforming.

Indeed, 150 homes in the 'hood have been evacuated.

I wonder what will happen if the cavern holding all that butane also fills up with water. Where will the gas go?

2. Another report From LA

More than 300 people in Assumption Parish are under a mandatory evacuation order as scientists try to figure out what caused a massive sinkhole in the swamp. The company that once had a salt mine near the site is about to start drilling a relief well to ease pressure underground.

Residents nearby were placed under a mandatory evacuation order, including Landry, not just because of the potential for additional collapse, but because of the more than fifty caverns underground.

One near the sinkhole site is being used as a butane storage cavern, a flammable, potentially explosive gas.
