The Earthquake Hazards Reduction Act of 1977 led to improvements in seismic safety, and in 1990, President Bush signed Executive Order 12699 to ensure that all new federal buildings are seismic resistant.
This order applies to all buildings financed by federal grants or loans and a training course was created to help individuals in government and the building and financial industries understand the requirements and implementation of the order.
The course also covers earthquake basics and how to construct buildings to be safe during an earthquake.
