Why did fewer die in chile’s earthquake than in haiti’s ? This is not me asking that strange question…Anthony Reuben on BBC News is asking that question. It’s more towards analysing the situation. He is right, the death toll of chile is much less compared to 220,000 toll of haiti. Why is that. Sure, chile is much more presperous and building qualities and relief work is swifter there. But it’s also because chileans know how to tackle earthquake. Chilean infrastructure organisations use a safe and proven seismic design code for new buildings, which makes them more stronger. the system is known as “Strong Columns Weak Beams”. the idea is that buildings are held by reinforced concrete columns, which are strenghtened by a steel frame.
Reinforced concrete beams are used to lay the roofs. If there is an earthquake , the idea is that the concrete on the beams should break at the ends which will dissipate much of the jolt-force of quake. But the steel reinforcement will remain and colums should stand upright , which means that the building will stay upright.
Chileans were lucky also , the epicentre was 21 miles underground, offshore and 70 miles fom the nearest biggest town. On the other hand the haitian quake was only 8 miles underground and right on the edge of port au prince.
