Description: 13 concrete protective vault segments were arranged on a 15" bed of soil and a 1" thick plywood sheet. Each vault segment was centered over its corresponding plywood sheet. Vault segments were positioned with 1.2" gaps. The joint between the middle two segments was centered on the fault. No sheet metal covers were present between segments.
