Africa-Press – Namibia. <\/strong><\/span>As a collaboration of researchers were mapping a geological fault stretching along the east coast of New Zealand’s North Island, analysis of rocks drilled up from the ocean floor showed they were abnormally “wet”, prompting the scientists to investigate further.<\/p>\n

A water reservoir as large as a sea lies buried deep inside Earth’s crust, locked there in the aftermath of volcanic eruptions 125 million years ago, research has revealed.<\/p>\n

This underwater basin was found 3.2km under the Pacific ocean floor, 15km away from the Hikurangi fault. The latter is a subduction zone believed to be the largest birthplace of earthquake and tsunami threats in New Zealand, according to research published in the journal Science Advances.<\/p>\n

The volcanic plateau which was formed during one of planet Earth\u2019s largest volcanic eruptions known to science during the early Cretaceous period, causing a massive lava plume, was revealed by a 3D seismic image.<\/p>\n

The fault had intrigued scientists because it has a history of producing \u201cslow-motion\u201d earthquakes. Another term for these tremors is \u201cslow-slip events\u201d and they are the result of tectonic pressure being released. But the mystery that the authors of the research sought to unravel was why these tremors occurred more often at some faults than at others. There had been speculation that buried water could cause these slow-slip earthquakes.<\/p>\n

University of Texas Institute for Geophysics (UTIG) researchers had relied on ocean research cruises and ocean drilling. The 3D seismic image of the volcanic plateau revealed layers of sediments around the buried volcanoes. After volcanic rock samples were retrieved in the course of drilling, it was discovered that water made up nearly half of their volume.<\/p>\n

\u201cNormal ocean crust, once it gets to be about 7 or 10 million years old should contain much less water,\u201d said study lead author Andrew Gase, at the time a post-doctoral fellow at UTIG.<\/p>\n

During the ancient eruptions, some of the volcanoes had been eroded to a degree that they became porous, locking in water, according to Gase.<\/p>\n

\u201cWe can\u2019t yet see deep enough to know exactly the effect on the fault, but we can see that the amount of water that\u2019s going down here is actually much higher than normal,\u201d he said.<\/p>\n

The scientists think that the ancient volcanoes and rocks that transformed over time into clays are storing huge volumes of water as they are further consumed by the fault. Furthermore, the same could be true for Earth’s other earthquake faults, said study coauthor, UTIG Director Demian Saffer.<\/p>\n
