Geoscientists Discover Massive Undersea Water Reservoir Off New Zealand’s Coast

3D seismic imaging and ocean drilling at the Hikurangi margin reveal a widespread and previously unknown fluid reservoir within the extensively hydrated (up to 47 vol % water) volcanic upper crust of the subducting Hikurangi Plateau large igneous province.

Revealed by 3D seismic imaging, the newly-discovered water reservoir lies 3.2 km (2 miles) under the ocean floor off the coast of New Zealand, where it may be dampening a major earthquake fault that faces the country’s North Island. The fault is known for producing slow-motion earthquakes, called slow slip events. These can release pent-up tectonic pressure harmlessly over days and weeks. 3D seismic imaging and ocean drilling at the Hikurangi margin...
