Dry stacked rock is not the only foundation type for cob.
My foundations are superadobe. I used curved walls for greater strength.
The superadobe foundation have handled at least one relatively major
earthquake
in  Hesperia Ca not too far from Los Angeles

Hi Folks,

I live in Southern California and more and more am attracted to Cob as
a 
sound economical and environmental way to build our future "mansion".
My 
question is how well does Cob really stand up to a major earthquake. I
see 
all kinds of reference to Cob laid down over dry stacked rock
foundations 
etc. Just seems like a lot of work to risk a foundation like that?
Even over 
a poured foundation I have to ponder the merits. I would love to hear 
anything at all positive for cobbuilding in our zone.

Thanks
Don Wells
