QuakeCoRE PhD Candidate Erin M. (University of Canterbury) presented at the QuakeCoRE Fault Displacement Hazard International Delegation Workshop at the University of Canterbury yesterday. Erin's research examines that fault surface deformation during earthquakes can trigger rapid coseismic river response (CRR) events, altering local flood patterns and hazards. Four main classes of CRR can occur and are influenced by site-specific factors such as channel type, topography, and fault characteristics. Hydrodynamic models successfully replicating the 2016 Papatea Fault Rupture and Waiau Toa / Clarence river avulsion confirms that flood modelling techniques can be combined with a newly developed 'F-Index' approach to assessing relative hazard at fault-river intersections ahead of time, aiding the proactive mitigation of CRR-induced flood hazard in high-risk areas. A number of invited international leaders in fault displacement hazard are in Ōtautahi Christchurch for this multi-day workshop based at the University of Canterbury. Showcasing the nature of interdisciplinary research, of the 60+ from Aotearoa and abroad spanned the fields of geoscience, civil, geotechnical and structural engineering, land use planning and disaster risk reduction to name a few. Today attendees are in the field at historical fault rupture sites in North Canterbury. #WatchThisSpace for further information on this QuakeCoRE International Delegation in the coming weeks. This event received additional funding from EQC Toka Tū Ake.

This newly released article in the ASCE Journal of Geotechnical and Geoenvironmental Engineering may be of interest to those investigating the liquefaction potential and sediment ejecta manifestation in thinly interbedded sands and fine-grained soils. The study examines the Palinurus Road site in Christchurch, New Zealand, subjected to the 2010-2011 Canterbury Earthquake Sequence, using simplified procedures and fully coupled 2D nonlinear dynamic analysis. The findings demonstrate the value of advanced 2D modeling with realistic soil spatial variability for understanding inconsistent ejecta predictions from simplified tools. The approach can guide future refinements to assessment procedures and provide insights into key factors controlling manifestation in complex stratified sites.

🌉⚛️ Impressive cool and educational al demo on the failure of earth dams 👨🏻🏫 Earth dams can fail due to many reasons, such as overtopping, seepage, structural weaknesses, foundation issues, flow failure or cyclic mobility liquefaction, and others. 🚨 Overtopping occurs when water exceeds the height of the dam, eroding the structure. 💧 Seepage can lead to internal erosion or piping, weakening the core of the dam. 🌉 Structural failures often arise from poor construction, inadequate materials, or design flaws. ⚛️ Foundation issues, such as differential settlement or liquefaction, can affect the stability of the dam. Regular maintenance, proper design, robust construction, and real time monitoring are crucial to preventing these failures, ensuring the integrity and safety of communities and infrastructure #science #engineering #geology #design #creativity #innovation #research #STEM 👨🏻🏫 Follow Felipe Ochoa Cornejo 👨🏻🏫🇨🇱 for more state of the art and innovative science, engineering, geology, and technology 🎥 by John Thetecky
