  • A new attraction-detachment model for explaining flow sliding in clay-rich tephras

    Kluger, Max O.; Moon, Vicki G.; Kreiter, Stefan; Lowe, David J.; Churchman, G.Jock; Hepp, Daniel A.; Seibel, David; Jorat, M. Ehsan; Mörz, Tobias (The Geological Society of America, 2017-02-01)
    Altered pyroclastic (tephra) deposits are highly susceptible to landsliding, leading to fatali-ties and property damage every year. Halloysite, a low-activity clay mineral, is commonly associated with landslide-prone layers ...
  • Sensitive pyroclastic soils in the Bay of Plenty, New Zealand: microstructure to failure mechanisms

    Moon, Vicki G.; Mills, Pip R.; Kluger, Max O.; Lowe, David J.; Churchman, G.Jock; de Lange, Willem P.; Hepp, Daniel A.; Kreiter, Stefan; Mörz, T. (New Zealand Geotechnical Society, 2017)
    Sensitive soils derived from weathered rhyolitic pyroclastic materials are associated with many landslides in the Bay of Plenty. Undrained, consolidated static triaxial tests show contractive p’-q’ plots, strain-softening ...
  • Subseafloor Investigation of Sediments at Southern Tauranga Harbour, New Zealand, before Capital Dredging

    Jorat, M. Ehsan; Moon, Vicki G.; Hepp, Daniel A.; Kreiter, Stefan; de Lange, Willem P.; Feldmann, S; Moerz, Tobias (Coastal Education & Research Foundation, 2017-03-01)
    The Port of Tauranga plays a key role in New Zealand's export–import industry, and capital dredging commenced in October 2015 to extend the shipping channels to accommodate larger container vessels. This study investigated ...
  • Utilizing piezovibrocone in marine soils at Tauranga Harbor, New Zealand

    Jorat, M. Ehsan; Moerz, T; Moon, Vicki G.; Kreiter, Stefan; de Lange, Willem P. (TECHNO-PRESS, 2015-07-01)
    Piezovibrocones have been developed to evaluate the liquefaction potential of onshore soils, but have not yet been utilized to evaluate the in-situ liquefaction behavior of offshore marine and volcanoclastic sediments. Two ...
