GEOLOGY

Detailed explanation-1: -A seismogram is the recording of the ground shaking at the specific location of the instrument. On a seismogram, the HORIZONTAL axis = time (measured in seconds) and the VERTICAL axis= ground displacement (usually measured in millimeters).

Detailed explanation-2: -A seismogram is a tracing of earthquake motion created by a seismograph. When Did It Happen? Seismologists use seismograms to cal-culate when an earthquake started. An earthquake starts when rock slips suddenly enough along a fault to create seismic waves.

Detailed explanation-3: -A seismogram is a record of the seismic waves from an earthquake. A seismograph or seismometer is the measuring instrument that creates the seismogram. Almost all seismometers are based on the principle of inertia: a suspended mass tends to remain still when the ground moves.

Detailed explanation-4: -A record produced by a seismograph on a display screen or paper printout is called a seismogram. Although originally designed to locate natural earthquakes, seismographs have many other uses, such as petroleum exploration, investigation of Earth’s crust and lower layers, and monitoring of volcanic activity.

Detailed explanation-5: -The paper recording of an earthquake is called a seismogram.
