  • Cold production of new seafloor
    on May 24, 2018 at 3:24 pm

    Magma steadily emerges between oceanic plates. It pushes the plates apart, builds large underwater mountains and forms new seafloor. This is one of the fundamental processes that constantly change the face of the Earth. But there are also times when new seabed is created without any volcanism, by un-roofing mantle material directly at the seafloor. Scientists have now published the first estimation based on seismic data on how much seafloor is produced this way. […]

  • Applying machine learning tools to earthquake data offers new insights
    on May 23, 2018 at 7:00 pm

    In a new study, researchers show that machine learning algorithms could pick out different types of earthquakes from three years of earthquake recordings at The Geysers in California, a major geothermal energy field. The repeating patterns of earthquakes appear to match the seasonal rise and fall of water-injection flows into the hot rocks below, suggesting a link to the mechanical processes that cause rocks to slip or crack, triggering an earthquake.

  • Shaking up megathrust earthquakes with slow slip and fluid drainage
    on April 9, 2018 at 3:26 pm

    Megathrust earthquakes are the most powerful type of earthquake, occurring at subduction zones -- where one tectonic plate is pushed beneath another. By contrast, slow slip events (SSEs) release seismic stress at a lower rate than large earthquakes, re-occurring in cycles. These processes can take place along the megathrust and other planes of weakness in response to loading, releasing low frequency seismic waves. Researchers in Japan consider the fluid drainage processes that can occur from SSEs and their impact on seismic activity. […]
