Doesn't the earthquake risk significantly curb LA's ability to build up as much as NYC? I think there are probably certain density limiting factors like this. Which just means that they need to adapt to what that means in terms of sprawl and moving people around.

Very tall buildings can actually be safer than shorter buildings, because they are all made of steel, and can have a lot of anti earthquake support built in.

Also as a short proof, Japan and Taiwan are also directly on top of a fault line. Taipei and Tokyo have some of the tallest buildings in the world. The tech is there.

DTLA has plenty of skyscrapers.

Tokyo is bigger than LA and NYC put together.
