Technical Evaluation

  
Parameters- what is measured
  • type of fault
  • age of displaced surface
  • number of repeated events/movement history

Management Evaluation

  
Original purpose.
  • Paleoseismology research
  • to better identify earthquake hazards
  • to better understand earth deformation in New Zealand
Relationships with classification systems. N/A
Relationships with other databases
  • The seismology database records earthquakes (this database has 50 years of data)
  • Geological maps of New Zealand
  • Earth deformation database
Known relationships with proposed EPIP indicators. N/A
Who uses this database? Users include regional councils, territorial local authorities, utility operators and the insurance industry. The database is used for planning and development phases for large projects as well as for ongoing management activities. Some councils are very proactive in their use of the database.
Public awareness of the database At a general level.
Database strengths.
  • national coverage
  • consistent scale 1:50 000
Database limitations.  

 

What are the Current and Emerging Uses of the Database for:

  
Assisting with determining historic state/baseline. The database identifies past earthquakes
Assisting with determining current state/baseline. N/A
Assisting with modeling possible future outcomes. N/A
Risk assessment. The database can be used to estimate earthquake and fault rupture hazard. This information can be used to modify infrastructure development.
Monitoring site selection and sample design. N/A
Aggregating and reporting data locally, regionally or nationally. N/A
