These features also give building designers more flexibility to create exterior walls, ceilings, and arrange building contents. These are a few of the basic structures that may be used in constructing earthquake-resistant buildings. A federal study last year found that a quarter of the buildings in the San Francisco Bay Area would be significantly damaged after a magnitude-7 earthquake, a disaster that would be compounded by . The reason Los Angeles has traditionally avoided so-called super tall towers is because the city is located on the San Andreas Fault line, an active earthquake zone. Small earthquakes triggered by seismic waves created by the detonation of the rock on the surface cause collapse of underground tunnels and mines. Mr. Kasalanati estimates that there are 175 base-isolated buildings in the United States, mostly museums, hospitals and older buildings like the city halls of San Francisco and Los Angeles that were retrofitted with isolators. ft. building rests on a series of suspension points, which effectively separate the building from the ground.
