Nearly two months after the Great Southern California ShakeOut earthquake drill was held, engineers involved in the earthquake simulation are concerned with weaknesses found in five area high-rise steel buildings. The results of the simulated 7.8 earthquake suggest that the five steel high-rise buildings in question might collapse in an earthquake of that magnitude.L.A.

The drill included several emergency facilities. At the Providence Holy Cross Medical Center football field. At Charter High school, an earthquake simulator was available for people to experience the feel of an earthquake and search and rescue teams at Caltech practiced extracting people in a maze of cardboard boxes.Communication systems and emergency protocols in California were also tested.

The exercises are expected to cost approximately $5 million, which is paid by federal grants.Los Angeles Times: Earthquake drill aims to prepare state (November 13, 2008)

It's hypothetical. Changing building codes is based on forensics, on what we've seen happen. Engineers are not willing to make changes on what people theorize might happen,—Luke Zamperini, principal inspector for the Los Angeles Department of Building and Safety.
