Though this fault line is not a subduction zone it does have an element that was not present in Chile.

This Whittier fault line is capable of producing what is called a “Super Shear” earthquake, where by the “Shear” or S/waves are channeled is such a way as being able to over take each other. What causes this is that the waves actually break the sound barrier while they are propagating outward from the fault quake.

There is much debate on what this actually means to the overall resulting damage from a quake, but it is thought that it holds the key as to why in some slip/strike earthquakes of the same magnitude, the damage is not.

Fascinating.

I’m wondering . . . would you and your cohorts be able to conjecture productively about . . .

ASSUME that a massive, long mountain ridge is to appear with great suddenness over much of the length of California . . .

where

would you expect such a thing . . . and to run from where in the South to where in the North?

And where might subsidence or sinking be on the West and/or East of such a rising ridge?
