Question

What will the reading on the Richter scale be for an earthquake that has an intensity of 3.8 × 10^6 and a reference value of 1? `(R = log (l/(l_0)))`

Answer 1

we are given

`I=3.8 * 10^6`

`I_0=1`

now, we can use formula

`R=log((I)/(I_0) )`

now, we can plug these values

we get

`R=log((3.8 * 10^6)/(1) )`

`R=6.57978`............Answer
