In the 1970s, a more accurate physical measure of the size of the earthquake was developed, …Earthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at that site. The slip of one block of rock over another in an earthquake releases energy that makes the ground vibrate. That vibration pushes the adjoining piece of ground and causes it to vibrate, and thus the energy …Magnitude is really a measurement of how large an earthquake is. Intensity is a measure of how badly the ground shakes when an earthquake happens. How it is measured; Magnitude can be measured by taking a measurement of the highest amplitude of the shear waves, or by recording how much a fault has been displaced.The magnitude scale is logarithmic, which means that each increase in magnitude represents a tenfold increase in the amplitude of the seismic waves. Earthquake magnitude can be recorded by seismographs. Therefore, the size of the seismic waves that an earthquake generates is used to determine its magnitude, choice b is right.9.2 Measuring Earthquakes. The shaking from an earthquake travels away from the rupture in the form of seismic waves. Seismic waves are measured to determine the location of the earthquake, and to estimate the amount of energy released by the earthquake (its magnitude ).
