WOW!
EC my thoughts and prayers are with you and everyone on the coast. This is not good and they are capping things off which means it's going to follow the path of least resistance and come up or out somewhere else they have no clue what to do or what they are dealing with when this blows or collapses it will be a cataclysmic event between the poisonous gases, radioactivity and all the illegal dumping of who knows what. Your sinkhole is a time bomb.
