GEOLOGY

Detailed explanation-1: -A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with “seismograph". Seismographs are instruments used to record the motion of the ground during an earthquake.

Detailed explanation-2: -A seismograph is the primary earthquake measuring instrument. The seismograph produces a digital graphic recording of the ground motion caused by the seismic waves. The digital recording is called a seismogram. A network of worldwide seismographs detects and measures the strength and duration of the earthquake’s waves.

Detailed explanation-3: -A device called a seismograph can be used to measure the magnitude of any earthquake.

Detailed explanation-4: -The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes. Sources/Usage: Public Domain.

Detailed explanation-5: -Seismograph is the instrument that records the tremors of an earthquake. This instrument also helps seismologists to map the interior of the Earth.
