What is the clearest indication that your community is seismically safe?

The adoption of a recent version of one of the model building codes, including its seismic provisions is the clearest indication that a community is seismically safe.

Modern building codes, such as the International Building Code (IBC), International Residential Code (IRC), and International Existing Building Code (IEBC), are legally enforceable, comprehensive, regularly updated, objective and incorporate the latest research and knowledge on seismic hazards and design requirements. These codes provide detailed provisions for seismic design, inspection, and construction, ensuring that buildings can resist seismic forces and minimize damage.
