Question

7.The moment magnitude M of an earthquake that releases energy E (in Ergs) canbe modeled by this equation: M = 0.291. In(E) + 1.17On May 22, 1960, a powerful earthquake took place in Chile. It had a momentmagnitude of 9.5. How much energy did this earthquake release?

Answer 1

Step 1

Define terms

M = 9.5

E = ?

Step 2

Substitute and find the value of E

`9.5\text{ = }0.291.\text{ ln(E) + 1.17}`
