Some features of disaster resistant houses
Natural disasters include hurricanes, earthquakes, wild fires and termites.
The ideal structure would be stiff at the bottom and light-weight at the top. It makes economic and structural sense to use a cinder block half-wall and to design around the material's limitations.
---added after RBD noted that I did not specify the material for the ring beam---While the beam can be virtually any material as long as it is available in long lengths and it can be joined to efficiently pass the loads from one length to the next, in most of Latin America poured concrete would be the material of choice. It is inexpensive and and can be poured to make a continuous beam.
The ring beam also serves to mitigate against termites working their way up the insides of the cinder blocks from the soil line.
Threaded studs are cast-in-place to attach the stud wall's sill plate.
Incidentally, metal roof for strength and fire resistance.
If the roof is painted white (steel), then the solar loading will be minimized as you wait for the power to come back on.
None of these features are incredibly expensive but they do require forethought and do add a little bit to the cost.
