Detailed explanation-1: -Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network. The earliest “seismoscope” was invented by the Chinese philosopher Chang Heng in A.D. 132.
Detailed explanation-2: -A seismograph is a machine which measures an earthquake.
Detailed explanation-3: -A seismograph is an instrument that measures and registers seismic waves that travel through the Earth as the outcome of an earthquake.
Detailed explanation-4: -Seismographs. 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.
Detailed explanation-5: -A seismograph or seismometer is an instrument used to detect and record seismic waves. Seismic waves are propagating vibrations that carry energy from the source of an earthquake outward in all directions. They travel through the interior of the Earth and can be measured with seismographs.
