GeoNet volcano status information can be returned using GeoJSON and RSS feeds.
These images are used to appraise the frequency of local earthquakes and the level of ground tremor at a volcano.
GeoNet's volcano camera images are an important part of the surveillance programme as any changes to a volcano can be observed and compared over time. Our cameras produce images periodically, with the frequency of image capture varying from camera to camera depending on the communications bandwidth to the site. During a volcanic event we may change the frequency of capture.

Exercise Ruaumoko was an exercise carried out in 2007/08 based on fictitious volcanic activity in the Auckland metropolitan area.
This allows the user to plot the relative motion of the sites over time and provides quality control information about the GPS data.
