Pumice materials, which are problematic from engineering viewpoint, are widely spread in many parts of North Island. Following the 2010-2011 Christchurch earthquakes, a clear understanding of their properties under earthquake loading is necessary. For example, the 1987 Edgecumbe Earthquake showed occurrences of localised liquefaction in…
