GEOLOGY

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.

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: -A seismometer is an instrument that measures the motion of the ground, caused by, for example, an earthquake, a volcanic eruption, or the use of explosives.

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