Development of detailed liquefaction case histories from the 1987 Edgecumbe Earthquake

Abstract Liquefaction and associated lateral spreading during the 1987 Mw 6.5 Edgecumbe earthquake caused severe damage within parts of the Whakatane township. Liquefaction primarily manifested proximal to the Whakatane River in areas underlain by recent fluvial and marine sediments. The development of ground motion intensity…

SPECIAL FEATURE Whakatane liquefaction case history from the 1987 Edgecumbe Earthquake: examination of an extensive CPT dataset supplemented by paleo-liquefaction investigations

Liquefaction and associated lateral spreading during the 1987 ML 6.3 Edgecumbe earthquake caused severe damage to parts of Whakatane, New Zealand. Recent studies utilizing extensive CPT investigations indicate that much of the Whakatane Central Business District is underlain by sediments with a low cyclic resistance…
