The 1906 San Fransisco earthquake killed over 3,000. A new technology could help shield buildings from seismic damage.
According to the U.S. Geological Survey, there are 500,000 detectable earthquakes every year, of which 100,000 will be felt and about 100 will cause damage. Engineers now use seismic vibration control technology - and base isolation in particular – to make buildings more earthquake-proof. But what about existing structures? Researchers from the University of Liverpool have now developed a means of effectively making buildings “invisible” to the destructive path of a quake.
