GEOLOGY

Detailed explanation-1: -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-2: -This record made by the seismograph is called a seismogram.

Detailed explanation-3: -A seismograph is a machine which measures an earthquake.

Detailed explanation-4: -The paper recording of an earthquake is called a seismogram.

Detailed explanation-5: -Because P waves are the fastest seismic waves, they will usually be the first ones that the seismograph records. The next set of seismic waves on the seismogram will be the S-waves. These are usually bigger than the P waves, and have higher frequency.
