An earlier model for a new mode of wave propagation in a saturated              porous medium is to be extended to explore an interior singular                 region of focussed pressure, which is postulated to represent a local           region of liquefaction (loss of solidity) of the porous medium.  A              mathematical model of this interior region will be developed and                matched to the previously obtained exterior solution.  An                       experimental demonstration that pressure focusing and liquefaction is           possible in the new propagating wave mode is included in the                    investigation.  The mechanism of pressure focusing in a propagating             wave to produce local liquefaction has possible importance in                   earthquake diaqnostics and failure mechanism.
