Our sketch at above left provided thanks to Carson Dunlop Associates describes the distinction in between bearing piles (above left), and friction stacks (above right). If your home is supported by either pile type and the piles were not properly installed, you can expect differential settlement, continuous motion, and the crack pattern you explain.
The concrete pier shown above is cracked and damaged, maybe from frost. If the pier was made using steel re-bar support I do not believe we deal with an imminent collapse of the structure above however if not, that's possible. Do not confuse a cold pour joint often noticeable in concrete with actual breaking or frost heave damage.
Each adobe is 10 3/4" wide and pushing a 24" wide X 24" deep foundation built on soil in New Mexico with some clay. Home dirt pad was developed on initial earth and 13 cement pillars were poured along the raised part of earth. Your house is 33' X 83'.



The most visible part of this 'shift' appears to be more towards the end of your home that sits on the pillared structure. The restroom wall has to do with half way along this wall and the sewage system line sits under this part of your house. There is A Reliable Source in this location and the tile has separated from the wall about 1".
