basically, it makes sinkholes. the only rock i'd say that we have in abundance that is particularly subject to liquefaction is limestone. the high water table here in sunny florida causes us a lot of sinkholes, something called karst topography.
Karst topography is caused by solution of the limestone, not by liquification.
Not at all an expert on the matter, by I suspect that the solution happened when the water tables were lower.
I think liquification happens to water saturated unconsolidated/unlithified sediments when shocked. I would think that "quicksand" is the prime example.
