• Exploring the effect of water on seismic wave attenuation in the upper mantle

    Updated: 2023-09-27 05:31:01
    The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the effect of water on the seismic properties of olivine rocks, finding that water retention in the asthenosphere can induce sharp drops in shear wave velocity. This also explained other seismic changes observed at the lithosphere-asthenosphere boundary. These findings provide invaluable insights into the diverse seismic activities on Earth.

  • Crucial third clue to finding new diamond deposits

    Updated: 2023-09-19 20:48:30
    Researchers studying diamond-rich rocks from Western Australia's Argyle volcano have identified the missing third key ingredient needed to bring valuable pink diamonds to the Earth's surface where they can be mined, which could greatly help in the global hunt for new deposits.

  • Earth's stability and ability to support civilization at risk: Six of nine planetary boundaries exceeded

    Updated: 2023-09-13 21:17:21
    A new study updates the planetary boundary framework and shows human activities are increasingly impacting the planet and, thereby, increasing the risk of triggering dramatic changes in overall Earth conditions.

  • Scientific ocean drilling discovers dynamic carbon cycling in the ultra-deep-water Japan Trench

    Updated: 2023-09-11 19:11:10
    Hadal trenches, with their deepest locations situated in the so-called hadal zone, the deepest parts of the ocean in water depth 6km, are the least-explored environment on Earth, linking the Earth's surface and its deeper interior. An international team conducting deep-subsurface sampling in a hadal trench at high spatial resolution has revealed exciting insights on the carbon cycling in the trench sediment.
