When seismographs are received at a station, the seismograph records the vibrations on paper in the form of lines. The height of the lines traced on paper is a measure of the energy released by the earthquake, also known as its

Magnitude

Explanation:

The height of the lines traced on paper is a measure of the energy released by the earthquake, also known as its "Magnitude"

Usually, the Magnitude" of vibration can be calculated by multiplying the vibration value by itself (10 x 10) and then double it.

Hence, in this case, the correct answer to the question is "Magnitude"

the correct answer would be true friction causes the faults to slip or collide
