An earthquake measuring 6.4 on the Richter scale struck Japan in July 2007, causing extensive damage. Earlier that year, a minor earthquake measuring 3.1 on the Richter scale was felt in parts of Pennsylvania. How many times more intense was the Japanese earthquake than the Pennsylvania earthquake? (Round your answer to the nearest whole number.)
Ayo, my fellows who searched here for the ANSWERS:
Tracking Earthquakes Quick Check:
1: Magnitude measures the energy released by the earthquake, while intensity measures the amount of damage.
2:There is more likely to be an earthquake in Region A than in Region B.
3: P waves push and pull in the same direction as the wave, and S waves move up and down.
4: the vibrations produced by an earthquake
Hope this helps :)
To find out how many times more intense the Japanese earthquake was than the Pennsylvania earthquake, we need to calculate the difference between their Richter scale magnitudes.
The difference in magnitude can be calculated using the formula:
Difference = 10^(a - b)
Where a is the magnitude of the Japanese earthquake (6.4) and b is the magnitude of the Pennsylvania earthquake (3.1).
Calculating the difference:
Difference = 10^(6.4 - 3.1)
Difference = 10^3.3
Difference ≈ 1995.2623
So, the Japanese earthquake was approximately 1995 times more intense than the Pennsylvania earthquake.
To find out how many times more intense the Japanese earthquake was compared to the Pennsylvania earthquake, we need to compare their magnitudes on the Richter scale.
The formula used to compare earthquake intensities is:
Intensity Ratio = 10 ^ (magnitude difference)
In this case, we need to find the magnitude difference between the two earthquakes:
Magnitude difference = Magnitude of the Japanese earthquake - Magnitude of the Pennsylvania earthquake
Magnitude difference = 6.4 - 3.1 = 3.3
Now, we can calculate the intensity ratio:
Intensity Ratio = 10 ^ (magnitude difference)
Intensity Ratio = 10 ^ 3.3
Using a calculator, we find that the intensity ratio is approximately 1995.3.
Therefore, the Japanese earthquake was approximately 1995 times more intense than the Pennsylvania earthquake.
