Earthquake Proof Building Foundations
Date: April 2003
What is put into the foundations of earth quake proof buildings to let them shake safely?
Civil engineers do not like to call them "earthquake-proof" because the very largest earthquakes
can be devastating to any building.
"Earthquake-resistant" might be a better term. There are several systems in use, but the most
prevalent ones involve bearings inserted between the building and the foundation made out of
rubber or two pieces of metal with a DuPont's Teflon (TM) coating in between.
If you want to learn more, go to an Internet search engine and search on "earthquake base
isolation". This should lead to many sites which discuss the concept in more detail. The
