Numbers 16: 32 And the earth opened her mouth, and swallowed them up, and their houses, and all the men that appertained unto Korah, and all their goods.
33 They, and all that appertained to them, went down alive into the pit, and the earth closed upon them: and they perished from among the congregation.
Rev. 12:16 And the earth helped the woman, and the earth opened her mouth, and swallowed up the flood which the dragon cast out of his mouth.
This thing with the sink holes is getting spooky.
