Yes dry stone walls are said to be Earthquake Resistant.
With a 5.8 earthquake from Mineral VA hitting the Baltimore MD area on 8/23/11. Very Rare! I exited the cinderblock building I was in. Standing out side wondering what kind of wave pool I was swimming in?
The benefit of Dry Laid Walls they will shift and move as the earth moves. Which can not be said for the Washington Monument. Now closed and under inspection for cracks in the top. What gives? Stone on the ground held together with mortar.
Crazy stuff for us East Coasters.
