Scientists just found a 'zombie volcano' in New Zealand.
Geologists have discovered a massive magma chamber below the Earth's surface, sitting near some of New Zealand's most active volcanoes.
Matthew Pritchard, a geophysicist at Cornell University refers to such examples as "zombie volcanoes" – because they show signs of life where it should be dead – having discovered similar examples in the central Andes mountain range.
Geologists say we'll probably find a lot more of theses zombie volcanoes now that radar satellites are becoming more advanced. They've probably always been lurking below the surface, we just had no way to detect them until now.
