Vast water body, larger than all oceans combined, discovered 700km below Earth's surface

Scientists from Northwestern University in Illinois, US, have unearthed a monumental reservoir of water concealed beneath the Earth's surface. This discovery, estimated to be three times larger than all the oceans combined, is located approximately 700 km below the Earth's surface.

This hidden but vast subterranean ocean, within a mineral known as ringwoodite, has far-reaching implications for our understanding of Earth's formation and the origins of its water.

Using an array of 2000 seismographs dispersed across the United States, researchers meticulously analysed seismic waves generated by over 500 earthquakes. The deceleration of these waves as they traversed the Earth's interior, particularly the core, provided compelling evidence of the presence of water within the rocks below.

Previously, theories posited that Earth's water may have been delivered through comet impacts. However, this recent revelation suggests an alternative narrative: that the planet's oceans may have originated deep within its core, gradually seeping out over eons.
