Auckland’s fibre network will be used to provide an insight into volcanic activity under the region, Stuff reveals. Researchers from Victoria University of Wellington and the University of Auckland will use fibre-optic technology, known as Distributed Acoustic Sensing (DAS), to find earthquakes of less than magnitude 1. Earth scientist Calum Chamberlain said an eruption on the Auckland Volcanic Field (AVF) was likely to happen sometime in the future, and earthquakes might provide some insight into the volcanic unrest in the area.
