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 or seismometer is the measuring instrument that creates the seismogram. Almost all seismometers are based on the principle of inertia, that is, where a suspended mass tends to remain still when the ground moves.

Detailed explanation-3: -The spring-suspended mass lags behind the motion caused by the earthquake, making the pen record the waves on the drum. This combination of instruments tells a seismologist the general direction of the seismic wave source, the magnitude at its source, and the character of the wave motion.

Detailed explanation-4: -Seismograph is the instrument that records the tremors of an earthquake. This instrument also helps seismologists to map the interior of the Earth.

Detailed explanation-5: -Seismographs are sensitive instruments that can detect, amplify, and record ground vibrations, especially earthquakes, producing a seismogram. Numerous seismographs have been installed in the ground throughout the world and form a seismograph network, monitoring earthquakes, explosions, and other ground-shaking events.
