Logrithmetic Problem question

Last week there was an earthquake that measured as a magnitude of 3.2 on the Richter scale. Today you hear on the radio that there was a second earthquake that was 27 times more intense than the first. What was the magnitude of the second earthquake on the Richter scale?

Answered by Damon
depends what you mean by intense.

If amplitude is 27 times
log A = 3.2
so A =1584
B = 1584 * 27 = 42792
log B = 4.63
