Each increase of 1 on the Richter scale means the earthquake is actually 10 times more powerful (for example a 2.0 earthquake is 10 times stronger than a 1.0 earthquake—not twice as strong).The Mercalli Intensity Scale is only useful for measuring earthquakes in inhabited areas and is not considered particularly scientific, as the experiences of witnesses may vary and the damage caused may not accurately reflect an earthquake’s strength. It is, however, used to compare the damage caused by earthquakes in different areas. Earthquakes are the vibrations caused by rocks breaking under stress. The underground surface along which the rock breaks and moves is called a fault plane. The focus, or “hypocentre”, of an earthquake is the point where it originated within the Earth. The point on the Earth's surface directly above the focus is called the earthquake epicentre.
Jan 11, 2021 · The Richter scale measures the magnitude of an earthquake's largest jolt of energy. This is determined by using the height of the waves recorded on a seismograph.

A seismoscope can also be used for the detection of underground movements. It indicates that motion has …Earthquake magnitudes are determined by measuring the amplitudes of seismic waves. The amplitude is the height of the wave relative to the baseline (Figure 9.13). Wave amplitude depends on the amount of energy carried by the wave. The amplitudes of seismic waves reflect the amount of energy released by earthquakes.
