A reader just sent this information about a salt dome mess in New Mexico.
New Mexico salt dome collapse –
2009 – NBC – Cavern could collapse, taking part of N.M. city
[snip] ” . . . . Over the past few decades, communities in Texas, Kansas, Michigan, Canada and Europe learned of similar underground danger only after cracks appeared and the ground began to sink. Regulators are trying to determine how to prevent future collapses by better managing a practice that’s used throughout the world.”
Does this sound familiar? – – – “Officials have set up a monitoring system that takes readings from tilt meters and pressure sensors every two seconds and averages them to determine whether there are changes drastic enough to trigger alarms.

A student’s blog entry – Possible new alternative for storing nuclear waste.
“For the US, who have quite a few underground salt deposits, it could be an option to replace the reprocessing of spent fuel that occurs in some other countries but, due to the concerns surround its possible use in nuclear weapons, does not happen in the USA.”
“East Germany stored its radioactive waste at a facility at Morsleben, in the eastern German state of Saxony-Anhalt. Shortly after the fall of the Berlin Wall, Angela Merkel, then the environment minister, allowed considerable amounts of radioactive waste from the affluent West to be dumped in the Morsleben salt deposits — despite the concerns of the Federal Authority for Radiation Protection and the opposition of local politicians. Because the facility is now classed as severely structurally damaged, it must be stabilized at great cost — some €2 billion is needed for permanent closure.”
