Since 6pm Thursday 30 January we have located over 50 earthquakes in the geothermal area just to the north of Taupō. We look at what exactly swarms of earthquakes are and what causes them.
For those shaken awake by Tuesday nights M5.3 Eketāhuna earthquake some of you may have spotted a M5.8 earthquake near Ruatōria at the same time, on our app and website, which then disappeared. Read on as we explain what happened and what ghost earthquakes are.

Welcome, haere mai to another GeoNet Data Blog. Today’s blog is about data archaeology, dealing with old data and how we sometimes have to work around not having all the information we ideally want. If you are a fan of Indiana Jones, this one is for you.
A volcanic eruption in Auckland will likely result in slow moving rivers of lava flowing through densely populated areas, which is why our scientists are looking to La Palma for lessons from its 2021 eruption.
Most who have travelled through the winding Desert Road in the central North Island, will be familiar with the striking steep-sided cone of Ngāuruhoe volcano. Did you know that until 1975, Ngāuruhoe was the most active volcano in Aotearoa New Zealand, erupting every few years on average. Today we explore the history of this volcanic icon.
