GeoNet and Landslides
GeoNet maintains a rapid response capability for landslides in New Zealand. The rapid response team consists mainly of engineering geologists and geotechnical engineers. The aim is to have team members mobilised within 24 hours of a major event. The criteria for activating a rapid response are landslides that cause any of the following:
- death or serious injury;
- subsequent catastrophic events (such as the breach of a landslide dam);
- direct damage of greater than NZ$1 million;
- economic losses of greater than NZ$10 million;
- threats to public health (such as contaminated water supplies);
- significant research interest.
The purpose of these missions is to ensure that appropriate advice is available to maximise public safety, and to collect reliable and consistent landslide information.
Current Landslide Monitoring
- Utiku Landslide: the monitoring of a slow-moving landslide at Utiku in the central North Island.
- Young River Landslide: the monitoring of the water level of a dam caused by the Young River debris avalanche of 2007.
- Port Hills, Christchurch: the monitoring of landslides in the post-earthquake Christchurch environment.
- Landslide: read the reports from the landslide rapid response team. s
