Abstract

Abstract: The New Zealand wine industry has experienced several strong earthquakes over the last decade. The research presented herein documents the damage data to legged wine storage tanks following the Seddon earthquake (New Zealand, Mw 6.5) on 21 July 2013 and Lake Grassmere earthquake (New Zealand, Mw 6.6) on 26 August 2013, and the 2016 Kaikōura earthquake (New Zealand, Mw 7.8). The data covers the damage assessment results of 1512 legged wine storage tanks from the 2013 earthquakes and of 599 legged wine storage tanks from the 2016 earthquake. Several parameters were investigated, including tank capacity, liquid level at the time of the earthquakes, and damage to different elements of legged wine tanks. Frame/leg parts of the legged wine tanks sustained the greatest damage, with 40% of legged tanks sustaining frame/leg damage in the 2013 earthquakes and 44% of legged tanks sustaining frame/leg damage in the 2016 earthquake. Based on the results, liquid level and tank capacity were identified as parameters that most greatly influenced the seismic performance of legged wine tanks. Graphical abstract: Unlabelled Image Highlights: The largest earthquake damage database to the legged wine storage tanks is presented herein. The available information allowed for comparison of the seismic performance of wine tanks, considering different parameters. Seismic performance of tanks with braced legs and with no braced legs was compared. Seismic performance of legged wine tanks was compared following the 2013 earthquakes and the 2016 earthquake.
