Match the earthquake measuring instrument with its correct description. seismograph measures strength of an earthquake; measurement is based on the size of seismic waves. 2 measures strength of larger earthquakes; measurement is based on multiple variables. 3 measures effects of an earthquake ...
Seismic magnitude is not a measure of the physical size of the earthquake fault (as might be quantified by its area or its slip) but rather of the amount of vibration that it emits. The appeal of the Richter magnitude scale is twofold. First, an earthquake is summarized by an easy-to-remember and easy-to-interpret single-digit number.
The strength of an earthquake can be measured as a function of intensity. The modified Mercalli scale ranks intensity from 1 to 12 according to the amount of resulting damage. This system is not totally accurate because the amount of damage is often proportional to the population in an area, the type of design and construction of buildings, and ...

Earthquakes are described in terms of what nearby residents felt and the damage that was done to nearby structures. Richter magnitude scale. Developed in 1935 by Charles Richter, this scale uses a seismometer to measure the magnitude of the largest jolt of energy released by an earthquake. Moment magnitude scale.
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.Let’s make it simple. If you don’t see the word “points” and see a fraction part, this is the measured strength of the earthquake, its magnitude. But it is more difficult to say if it is according to Richter or Kanamori. Most likely, if the magnitude is up to 5 points, it is Richter, higher – Kanamori. But this is not accurate ...
