Liquefaction Action, Possible Big One Reaction?

Consider the popular “Big One,” a magnitude 7.2 earthquake to be generated by the West Valley Fault. This predicted magnitude is lower than the 1990 Luzon earthquake. However, it is not something to be belittled. Given the population and urbanization of Metro Manila, the effects are expected to be devastating.

Let us Investigate!
Keeping in mind the geology of the area, the overlying man-made structures, and the strength of the earthquake, what degree of liquefaction can you expect from the “Big One?”

Do you think it will be similar to the liquefaction caused by the 1990 Luzon earthquake?
