Question

Seismologists use two main devices to
measure an earthquake, a seismograph and
seismoscope. The seismograph is an
instrument that measures seismic waves
caused by an earthquake.
Explain this statement ​

Answer 1

Answer:

Seismograph, instrument that makes a record of seismic waves caused by an earthquake, explosion, or other Earth-shaking phenomenon. Seismographs are equipped with electromagnetic sensors that translate ground motions into electrical changes, which are processed and recorded by the instruments’ analog or digital circuits. The terms seismograph and seismometer are often used interchangeably; however, whereas both devices may detect and measure seismic waves, only a seismograph possesses the capacity to record the phenomena. A record produced by a seismograph on a display screen or paper printout is called a seismogram.
