Suppose earthquake A measures 32 on the Richter Scale What w

Suppose earthquake A measures 3.2 on the Richter Scale. What was the Richter scale measure of earthquake B if it was 1900 times more powerful than earthquake A?

Msf = log(Isf/S)

8.3 = log(Isf/S)

Now Msa = log(Isa/S)

Given Isa = 1900Isf

So, Msa = log(1900Isf/S)

= log 1900 + log(Isf/S)

= 3.278 + 3.2

= 6.478
