Sagot :
Answer:
The intensity of the 1964 earthquake was about 20 times the intensity of the 2008 earthquake.
Step-by-step explanation:
To compare the intensities, we first need to convert the magnitudes to intensities using the log formula. Then we will set up a ratio to compare the intensities.
Convert the magnitudes to intensities and write them in exponential form.
R=logI
1964 earthquake:
9.2I=logI=109.2
2008 earthquake:
7.9I=logI=107.9
Form a ratio of the intensities.
intensity for 1964intensity for 2008
Substitute in the values and divide by subtracting the exponents to find
109.2107.9101.3≈20.
The intensity of the 1964 earthquake was about 20 times the intensity of the 2008 earthquake.
Your answer:
The intensity of the 2008 earthquake was about 30 times the intensity of the 1964 earthquake.
Answer:
