There are 2 earthquakes are given below;
1st earthquake's magnitude is M=7.1 and the 2nd earthquake's magnitude is M=5.2 on the Richter scale.
How many times 1st earthquake has a magnitude greater than 2nd earthquake about?
( On the Richter scale, the magnitude M of an earthquake of intensity I is expressed by the formula: M = log10I.)

Yanıt Açıklaması:
For the first earthquake, the intensity is; M = log10I› 7.1=log10I› I=107.1
For the second earthquake, the intensity is; M = log10I› 5.2=log10I› I=105.2
on the Richter scale yields an intensity change by a factor of
107.1/105.2 =101.9=79.43
Strictly speaking; the fist earthquake had a magnitude about 80 times greater than second earthquake.
