__________
Most heavily damaged structures appear to be those constructed of masonry and concrete which are less flexible than structures made of resilient steel, wood-framing and fabric (tents) which appear to have survived or suffered much less damage. Structures built of concrete masonry units (CMU), if unreinforced with steel mesh or bars, are especially vulnerable to shaking. CMU is portable, cheap, fire-proof and easy to construct by low-skilled labor, thus commonly used in low-cost buildings. A common strucutral system is to use CMU as supporting walls, with cast-concrete floor and roof plates — collapse of the walls leads to lethal pancaking of the concrete plates.
