Why Haiti's smaller quake was worse than Chile's
By Colin Stark, Special to CNN
Poverty is what ultimately kills most people during an earthquake. Poverty means that little or no evaluation is made of seismic risk in constructing buildings and no zoning takes place. It means that building codes are not written, and even if they do exist they are difficult, or impossible, to enforce. It means the choice between building robustly or building cheaply is not a choice at all.
Haiti is a tragic illustration of this. Weak building materials and poor construction standards share much of the blame for the grotesque numbers of fatalities, injured and internally displaced people.
