Then you would have to bag you waste.. but that is another story.
It depends on the kind of disaster you're talking about. As Kayelle said, it would work in her area because the buildings would be unsafe after an earthquake, and I believe she doesn't live near a body of water.
As I've said several times, we used buckets of water to flush toilets after we lost water service following a hurricane. Burying waste when there's flooding going on isn't feasible.
