This caused by ground movement due to either extra moisture in the soil or the soil losing a great deal of moisture and shrinking. generally, if the foundation is not up to the mark, then this will happen. You need at least 9 inches or concrete for the foundation spreading 9 inches either side of the outer brick line.

The only cause of that crack is call soil erosion ,which can be happen by soil run or water damage .
