Flagship Leader: Misko Cubrinovski ( )

Flagship Deputy:  Sjoerd van Ballegooy

Flagship Summary

This flagship will develop new approaches and methodologies for quantification of impacts of soil liquefaction on land and infrastructure through a fundamental understanding of onset and consequences of liquefaction; and use these methods to assess liquefaction impacts throughout New Zealand and their potential to be mitigated.  These novel methods will represent a major advance in the field, and will provide means for a robust assessment and treatment of liquefaction hazards at both site-specific and regional levels. The key thrust areas are:


  1. Development and improvement of liquefaction assessment methods (Liquefaction Evaluation: Beyond Current State-of-Art and Practice). Utilize the exceptional databases compiled during Canterbury and Kaikoura Earthquakes, and obtain additional high-quality data where needed, to develop new or improve existing liquefaction evaluation procedures (field, laboratory and analytical tools and methodologies) that will adequately address current and future society needs for performance of land and infrastructure during earthquakes.
  2. Identify critical issues and ground conditions related to liquefaction impacts on infrastructure, including characterization of important but challenging New Zealand soils, and the development of adequate assessment procedures and cost-effective mitigation strategies.
  3. Development of performance based criteria for micro systems (e.g. soil deposits; soil-foundation-building systems) and macro systems (urban areas; land use and development) and lifeline networks, integrating geotechnical engineering knowhow within cross-disciplinary tools and methodologies.



Thrust Areas

Key tasks/Deliverables



FP2.1  Liquefaction Evaluation: Beyond Current State-of-Art-and-Practice 

1. Develop methodologies for assessment of liquefaction susceptibility and triggering; liquefaction-induced ground deformation



2. Integrate field, laboratory and computational tools to develop next-generation liquefaction methods and procedures



FP2.2 Liquefaction Vulnerability of New Zealand Land and Infrastructure

1. Examine, through field and laboratory investigation, typical New Zealand soils that are challenging for liquefaction assessment (silty soils, pumiceous soils and gravelly soils; soil composition, soil micro-structure, ground conditions, details, overall deposit characteristics)



2. Compile, summarise and interpret historical evidence of liquefaction in New Zealand (paleo-liquefaction studies)



3. Develop liquefaction assessment procedures for challenging soils



4. Enhance observations from Canterbury and Kaikoura Earthquakes with experimental and analytical studies to improve performance assessment of characteristic infrastructure



FP2.3  Liquefaction Assessment and Mitigation: Systems Approach

1. Develop assessment methodologies for micro and macro systems: Soil-foundation-building system (shallow and pile foundations); building-soil-building systems; bridge system



2. Evaluate liquefaction impacts on spatially distributed systems and networks (transportation networks; pipe networks)



3. Develop a framework for performance based criteria incorporating planning, management, operational, owner and user’s perspectives in engineering evaluations of liquefaction impacts



Historical Liquefaction Online GIS-based database

Records of liquefaction following large earthquakes within New Zealand have been collated and digitized into an online GIS-based database as part of FP2 project 17141/  FP2.2.2 which is now available to share


A read-only version of the QuakeCore historic liquefaction database located at:

This is read only version does not require a login. 
Data can be selected and exported using the selection widget.
Select data by drawing a rectangle or polygon
