This discuses the weakness of the materials.

This one has some tims to strengthen a particular time of constructions.

Evidence is given if you google “earthquake reconnaissance report” in regular mode or image mode.

Here is some great infomations on solutions.

There are some examples of earth and brick buildings that have been historicly designed for this with diagonal bracing in Turkey, and Portugal (after a huge quake).

I have read about this prviously. I do not know if the suggestions in the following links are sufficiently safe as this is a new search for the subject and my lack of technicle expertease.

The chinese have experimented with a sand bearing between the foundation and the walls. Boats work well too.

* The basics of the subject is called strength of materials and is studied by civil engineers. Text books are available. Some of this info is in the introductory part of Earth Qake Tips document linked above.
