    These seismogram displays depict ground motion recorded by seismograph stations in real-time, updated every few minutes Each plot represents 24 hours of data from one station
  • What is a seismograph and how does it work? | SAGE - IRIS
    A seismograph is a device for measuring the movement of the earth, and consists of a ground-motion detection sensor, called a seismometer, coupled with a recording system

  • Seismographs - Keeping Track of Earthquakes | U. S. Geological Survey
    Seismic waves lose much of their energy in traveling over great distances But sensitive detectors (seismometers) can record theses waves emitted by even the smallest earthquakes When these detectors are connected to a system that produces a permanent recording, they are called seismographs
  • How we record earthquakes - NRCan
    During an earthquake, vibrations caused by the breakage of rock along a fault zone radiate outward from the point of rupture The instrument used to record and measure these vibrations is called a seismograph
