which is the most susceptible to liquefaction: a town on a mountain; build on bedrock; buil in river valley?

Question

which of the following towns would be most susceptible to liquefaction: a town on a high mountain, a town built on bedrock, or a town built in a river valley?

Answer 1

the town in the river valley. the soil would be most saturated with water there.

Answer 2

Definitely the one in the river valley.
Liquification has nothing to do with water. It is the tendency for loose soil to not hold together during an earthquake (much like quicksand without the water in it).
