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
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?
