Scientists think they could have found the cause of a series of “slow-motion” earthquakes that have shaken New Zealand in recent years – a hidden ocean which sits two miles beneath the sea floor. The water was revealed as part of a giant volcanic area formed about 125 million years ago, when an eruption forced a plume of lava bigger than the US to the surface of the Earth. Researchers found the region by towing 3D seismic sensors behind a boat to build up an image of the ancient volcanic area. There, they found thick, layered sediments around long-buried volcanoes which contained much more water than expected. Andrew Gase, from the University of Texas Institute for Geophysics, who carried out the research, said: “Normal ocean crust, once it gets to be about seven or 10 million years old should contain much less water.” The ocean crust scanned by researchers was 10 times as old as this – but water made up nearly half its volume. The tectonic fault line which runs through New Zealand is known for producing slow-motion earthquakes, also known as slow slip events. During one of these, the energy from an earthquake gets released over days or months, often causing little or no harm to people. Scientists don’t know why they happen more at some faults than at others, but they are thought to be linked to buried water. Finding this new area of water at the fault line which creates so many slip events could provide an explanation. Gase said: “We can't yet see deep enough to know exactly the effect on the fault, but we can see that the amount of water that's going down here is actually much higher than normal.” If researchers can work out how the water reserves affect slip events – possibly by dampening them – they could, in turn, understand normal earthquakes better. Scientists also think underground water pressure could play a key part in creating conditions that release tectonic stress via slow slip earthquakes. As a result, Gase said scientists should drill even deeper to find out where the water ends up. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Scientists have found an explanation for a 'gravity hole' in the Indian Ocean. A gravity hole is an area where gravitational pull is low, causing the seafloor to sink. Deep beneath the ocean, there is one that is three million square kilometers in size and previously it has confused scientists. Now two researchers from the Indian Institute of Science, Debanjan Pal and Attreyee Ghosh, think they have solved the mystery. More than 1,000 kilometers (621 miles) beneath Earth's crust, they found cold, dense remnants of an ancient ocean plunged into a 'slab graveyard' beneath Africa some 30 million years ago, stirring up hot molten rock. Sign up to our free Indy100 weekly newsletter Pal and Ghosh retraced the formation of the massive geoid by modeling how tectonic plates skimmed over Earth's mantle for the past 140 million years. They ran simulations and compared the shape of the oceanic low those models predicted with observations of the dent itself. The models that reproduced the Indian Ocean geoid low in its current form all had one thing in common: plumes of hot, low-density magma wafting up beneath the low. These plumes, as well as a distinctive mantle structure, are what created the geoid low; if they rise high enough, Pal and Ghosh reckon. "In short, our results suggest that to match the [shape and amplitude of the] observed geoid low, plumes need to be buoyant enough to come up to mid-mantle depths," the pair wrote. The first of these plumes appeared about 20 million years ago, to the south of the Indian Ocean geoid low, and around 10 million years after the old Tethys Sea sank into the lower mantle. As the plumes spread beneath the lithosphere and inched towards the Indian peninsula, the low intensified. But more research needs to be done to work out what is really going on as not all scientists are convinced. Science is crazy. Have your say in our news democracy.
