[3]

An earthquake is a sudden, violent shaking of the ground caused by the sudden release of energy in the Earth’s lithosphere that creates seismic waves. Earthquakes range in size from those so weak people cannot feel them to those so violent they destroy cities. The word earthquake describes any seismic event, whether natural or caused by ...Types of Magnitudes Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.How are Earthquakes Measured?
