The DEVORA Borehole Database is an open resource that collates lithologic borehole information across the Auckland region. Each borehole entry includes technical (collar) information plus information on geology and hydrology (water level). The database currently holds over 2,300 borehole records. This information is key to understanding Auckland’s subsurface and will help in identifying the likely volcanic and seismic hazards to Auckland’s population, infrastructure, and economy.
The DEVORA Borehole Database is publicly accessible through PETLAB, the national rock database managed by GNS Science. A simple PETLAB query will produce a list of all DEVORA logs in PETLAB. Geologic information is contained as samples within associated features:
- Collection Name: DEVORA (DEV)
- Result Type: Feature
For information on accessing and downloading the DEVORA data from PETLAB, please download our PETLAB User Guide:
