Earthen walls do well in white areas of BSI's map
Where quake forces are likely <0.25 g or less, traditional earthen huts last hundreds of years unless they decay. Use water-resistant base courses and a roof overhang to prevent damage.
Earthen buildings moderate humidity and temperature swings. Techniques include traditional adobe, puddled adobe, cob, rammed earth and compressed blocks as well as most kinds of plastered earthbag.
