Answer: magnitude of an earthquake with an energy release of 7.079 X 10^26 =8
Step-by-step explanation:
Given that the magnitude M of an earthquake can be expressed by the equation
M=(2/3)log E - 9.9
Given that Energy release , E=7.079 X 10^26
Magnotude , M=(2/3)log E - 9.9
=2/3 log7.079 X 10^26 -9.9
2/3 x 2.8499719 -9.9
17.8999813 -9.9
=7.9999
rounded to 8 magnitude
