The initial aims of the the network were to record seismic activity in the two main transform zones of Iceland, the South Iceland Seismic Zone and the Tjörnes Fracture Zone, with a focus on capability to locate small earthquakes for the purpose of monitoring fault initiation, mapping of active subsurface faults and earthquake forecasting. As the network has expanded into the countries volcanic zones, the emphasis has also come to include mapping sub-surface magma migration in the many active volcanoes of Iceland for the purpose of monitoring and forecasting volcanic eruptions.
