←Map data/North Island Fault System

For a much more comprehensive database of North Island Fault System faults go to GNS NZ Geology 2.0.0 1 in 250 faults

This data is used on multiple relevant maps rather than just a map of North Island Fault System. Always assume that the manual processes involved could result in transcription inaccuracy and refer to original sources when appropriate. It shows known active southern North Island Fault System faults but most north eastern NIFS active strands are presently mapped in Map data/Whakatane Graben for easier logic context.

The data on land faults is by default from NZ Onshore Active Faults Database which may have been interpreted from the 2023 version of the fuller fault and postulated active fault data base at NZ 1:250K Geological GNS science. Where ever possible additional detail is from original academic work and these sources are referred to inline in the datafile. Some simplification was undertaken. The academic references include:

Technical Note
The data file itself is only valid json once served up as pagecontrol logic has been added. It was developed as valid json and for this see original file uploads before page control logic added. The file served up can vary from the default file based on the pagename of the calling page. The logic is mainly based upon case switching but also can colour or widen some traces using if statements. You can not debug this complete datafile now in sandbox (or a Json checker which is best for pure Json debugging) but can debug sections in a preview when editing a relevant pagename. The master map with all detail takes about 3 seconds to render first time. There is a cut off of 10 seconds built into wikipedia for such scripting. So although this data file is safe, it is known that with more complex maps, or multiple maps on a page you can run into time issues. It is possible to render more than one data file in a map and this is done using data in Map data/Whakatane Graben which as abridged version of the full file only takes 0.7 second to render. Once rendered Wikipedia serves up an image file of the map which is much faster but can lose detail and does not have mouse over functionality. Detail is always revealed by clicking on the map.

Key
Map showing known active surface faults associated with North Island Fault System. Faults in the Taupō Rift and the Hawkes Bay earthquake zones are not shown. By default faults are rendered in red, but the main strands are coloured as in the main active fault strands map. Thus Wellington Fault (blue), Ruahine Fault (light blue), Mohaka Fault (purple), Wairarapa Fault (orange), Waiohau (dark blue), Whakatane (light green), Waimana (orange), and Waiotahi (pink) to aid contextual interpretation. Clicking on the map enables a version with mouse-over display of individual fault data enabled.
