One earthquake has a magnitude of 3. 5. If a 2nd earthquake has a magnitude of 4. 5, then the seismic waves of 4.5 would be 10 times larger than the 3.5.
The Richter scale measures the energy of an earthquake. A seismic wave is a wave of acoustic energy that travels through the earth. It can result from an earthquake, volcanic eruption, magma movement, a large landslide, and a large man-made explosion that produces low frequency acoustic energy. Seismometer allow us to detect and measure earthquake by converting vibrations due to seismic waves into electrical signals. Earthquake magnitude is a measure of the size or amplitude of the seismic waves generated by an earthquake source and recorded by seismographs.The seismic energy of earthquakes can be found from its value over a half-period of the maximum swing.
Because of the logarithmic basis of the scale, each whole no. increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.
Thus, an earthquake measured 4.5 would have around 10 times more larger seismic waves than 3.5 following logarithmic scale.
