I don't know how they would know what the extent or strength of a future earthquake would be.

But I can assure you, with building made of masonry and if they're have been no retrofitting of most all structures, for an earthquake of that size, there would probably be considerable, wide spread damage.

Being anywhere near the epicenter of a 7.5 quake, you're going to think the world is coming to an end.

A 7.5 will make parked vehicles bounce off the ground, so one can imagine what it could do to structures, especially structure that have not been retrofitted.
