During this three-day colloquium, a group of professionals with expertise in earthen conservation, materials science, construction, building standards, and earthquake engineering gathered to discuss the current state of knowledge and the challenges of preserving our earthen cultural heritage in active seismic zones. This publication contains a selection of papers presented at the colloquium, as well as several later submissions by participants.
