Thank you Shannon. That sounds very much like what, ahem, Gernot Minke wrote in that free on-line manual that I'm NOT going to post the link to today. Even if he was mostly talking about non-straw uses. It also sounds (again with "just earth") very much in accord with the pictures from Bam. .................

The weakness appears to be a function of wall height relative to thickness, roof strength and load, and probably other things like bond beam (or lack there of). This makes sense from a purely intuitive perspective (at least to me), imagine a block of cob which is 8' high x 8' wide x 8' deep versus a block that is only 1 foot deep, it seems obvious that the one foot thick block will be far more likely to break apart when subjected to an earthquake. History (and the recent earthquake in the middle east) back this up, the earthen buildings with the thickest walls consistently survive far better than the ones with thinner walls. _________________________________________________________________ Get a FREE online computer virus scan from McAfee when you click here. http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963
