As someone who lives on a very active part of the Pacific Ring of Fire ( Southern California) the advances that are occurring in design to withstand this potential disaster are extremely exciting!

Yesterday in Japan some scientists tested this design process by subjecting a 6 story condominium structure to a 7.5 magnitude earthquake and the structure survived with little damage!  The piece on NPR’s All Things Considered is here:

Here is a video about the lab in Japan where the test took place.  While not the video of the actual event it is very well done and present the topic with great clarity. Courtesy of National Geographic (

The field has advanced to the point where annual conferences are being organized and learned papers being presented like at this recent conference (

It is looking like the old rule about earthquake building code where it is only there to make the building stand up long enough for you to get out before it falls down a thing of the past.

As always I thank you for your time and interest. Please take the time to Digg, Stumble Upon or add to the other social network of your choice to help me spread the word about these issues. Please forward any questions or suggestions to:
