  • A.Seismogram
  • B.Seismograph
  • C.Tectonic movement
  • D.Seismology

Answer: A

The record is called a seismogram.

A seismograph is the instrument that detects and records the vibrations of an earthquake, and the graphic trace it produces is the seismogram, showing the arrival of the P, S and surface waves.

The seismograph is the instrument, not the record. Seismology is the science of earthquakes, and tectonic movement is the movement of the earth's plates that causes most earthquakes.
