The council's emergency management team has been working with Selwyn communities to get ready. Langridge said researchers in California and New Zealand have a long history of earthquake science collaboration and are learning from each other about the treatment of active faults and fault segmentation for seismic hazard models. The borehole that was drilled will be used for further research, including to monitor changes over the years. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. Because of this, there are a limited number of places where scientists can have easy access to study it in detail.
