Earthquake intensity Intensity is a qualitative measure of the strength of shaking caused by an earthquake determined from the observed effects on people, objects and buildings. Magnitude. A familiar analogy to help understand earthquake s Magnitude describes the overall size of an earthquake as an event in the earth. Magnitude represents the total energy the earthquake radiates, and is calculated using information on how large an area moves, the distance that one side of the fault moves past the other, and the rigidity of the rock. Magnitude is the most commonly used measure to describe the overall strength or size of an earthquake. The magnitude of an earthquake is expressed in decimal fractions and whole numbers. For example, a magnitude of 5.3 is considered a moderate earthquake whereas a magnitude of 6.3 is a strong earthquake. Magnitude is the most commonly used measure toFast Fact: Measuring Earthquakes. Earthquakes are measureA seismograph is a primary earthquake measurin The moment magnitude scale (MMS; denoted explicitly with M w or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment.It was defined in a 1979 paper by Thomas C.
