There's a guy in California study newspapers missing dogs and cats ads----there's always an increase of X times of household pets before a big earthquake hit. So I guess we'll need to wait to see if this turns out to be true in this 8.9 quake......
But USN's LCACs could move above those piles of debris....
I think that's what USN is doing, loading one of the assault landing ship with LCACs in southern Japan, and will move to the area to conduct relief operations.
