    Solution:

    Concept: By turning the vibrations caused by seismic waves into electrical impulses, which we can subsequently show as seismograms on a computer screen, seismometers enable us to detect and monitor earthquakes. Seismologists research earthquakes and can utilise this information to pinpoint an earthquake's location and size.
     A device used for detecting earthquakes is called seismometer or Seismograph.
    1-It also tells the intensity of the vibration of earthquakes and makes a graph of it .
    2- Seismos means earthquakes and graphs means record or writing .
    Hence, the correct option is 4.
