Wattle and daub Bahareque
Wattle and daub is one of the oldest construction techniques known to mankind. It has been and still is used on every continent. "Wattle" describes a woven timber structure where twigs and branches are interlaced with rods and sticks. This support then may get plastered with "daub" to make the wall more hermetic, or left without to allow for a better air circulation which is especially appreciated in the tropics.
"Bahareque" and "quincha" are two Latin-American terms describing very similar construction methods. In Turkey the technique is known as "bagdadi". The German word
"Wand" (wall) derives from the verb "winden" (to wind around, or weave), describing in Germanic times a light-weight wall made of wattle and daub as opposed to the heavier wall "Mauer" introduced by the Romans ("murus" in Latin). Subconsciously and 2000 years later this difference in weight can still be felt by German speakers who would call a partition wall a "Wand" rather than a "Mauer".
The reduced weight and inherent cohesion of the system makes it particularly appropriate for earthquake prone areas as compared to masonry.

Background documentation
Most research on wattle and daub focuses on the material properties i.e. longevity of the wattle (wood) and daub (mud or lime). For more earthquake related information please refer to the dhajji/himis section.
