New computational methods in tsunami science

  • How do scientists analyze a tsunami?

    By unearthing sediment deposits tsunamis leave behind, scientists can study the waves' origins, extent, and frequency.
    Such work helps avert surprises from locations that have the geological apparatus to produce a tsunami, but haven'tin written history, at least..

  • What is the computer simulation of tsunamis?

    TsunamiLab is a web platfom that allows interactive simulation and visualization of tsunamis.
    It can be displayed as a normal website or as a hologram..

  • What technology is used to detect tsunamis?

    A DART system combines a surface buoy and a sensor on the ocean floor.
    This sensor detects changes in water pressure and seismic activity and transmits the data back to the surface.
    If these changes indicate a tsunami may form, the buoy signals an alert via satellite to the Tsunami Warning Centers in Alaska and Hawaii..

  • Since tsunami waves travel through the entire water column, these pressure sensors will detect the waves.
    These instruments are called DART buoys, which stands for “Deep-ocean Assessment and Reporting of Tsunamis.” The deep-sea gauges send information from a surface buoy through satellites to the warning centers.
  • What is a tsunami? A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor.
    This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.
Computational acceleration by adaptive mesh refinement, hardware acceleration by GPU utilization and parallelization make real-time tsunami forecast technically feasible.
