Shower wall tile: Paper, wire, morter vs cement board

I am installing marble tile in a shower wall.

I have conflicting opinions. I live in Southern California, which experiences regular earthquakes.

Regarding wall preparation:

It has been suggested that waterproof paper, wire mesh and a cement float be used to prepare for the tile, with paper and wire nailed directly to the studs (new construction).

It has also been suggested that I first install either green board, cement board or even plywood to improve the "earthquake resistance" of the installation.

Any comments / suggestions?

Thank you.

I'm afraid never having to prepare a wall for earthquake resistance limits my ability to answer completely. However, my best opinion would be to go with the plywood as the plywood under great stress would not crack as would the cement, and would prevent more screws from popping as with tile-board. If it were my house, I would also screw the plywood to the studs and use plastic washers for that tiny bit of give.
Like I said this is merely my opinion, but I hope it helps.
