Japan has recently deployed a fleet of cutting-edge seafloor monitors designed to capture real-time data on slow slip earthquakes-subtle tremors that shift portions of tectonic plates over days or weeks instead of seconds. These monitors utilize advanced pressure sensors and seismometers anchored on the ocean floor, allowing scientists to detect minute movements along fault lines previously undetectable by land-based instruments. By monitoring these slow slips more accurately, researchers aim to unlock patterns that could link them to the onset of larger, destructive earthquakes, potentially transforming early warning capabilities in the seismically active region.

Key features of the new system include:

  • High-sensitivity strain gauges for capturing gradual plate deformations
  • Real-time data transmission…
