How the change works
- 01 / Public decision
Rules and Responsibilities
- 02 / Physical change
Appropriate inspections and details
- 03 / Possible outcome
Reduced vulnerability
A building standard becomes protection through calculations, construction details, inspections and maintenance.
Research and local documents ↓What the evidence tells us
Engineering surveys on the 2010 Chilean earthquake document the performance and critical aspects of buildings. They allow us to learn from harm without reducing security to the mere existence of a rule.

The diagram compares choices and conditions for putting them into practice. Measured outcomes and their limits are discussed in the evidence.
Research and local documents ↓Conditions and limits
Magnitude and immediate shock are not the same thing. The comparison with earthquakes in other countries does not isolate the effect of building codes and no building is indestructible.
Other possible benefits
Greater continuity of services and protection of built heritage.
