The intensity levels I of two earthquakes measured on a seismograph can be compared by the formula
log
| I1 |
| I2 |
= M1 − M2
where M is the magnitude given by the Richter scale. An
earthquake of magnitude 6.4 hit a city. Two years later, that same
region experienced yet another, more devastating earthquake, this
time with a magnitude of 9.0. How many times greater was the
intensity of the second earthquake? Round to the nearest whole
number.

The Richter scale is used to measure the intensity of earthquakes, where intensity corresponds to the amount of energy released by an earthquake. If an earthquake has an intensity of x, then its magnitude, as computed by the Richter scale, is given by the formula R(x) = log X where is the intensity of a small measurable earthquake. (a) An earthquake in city A had a magnitude of 4.0 the Richter scale and an earthquake in city B measured 5.0....

The intensities of earthquakes are measured with seismographs all over the world at different distances from the epicenter. Suppose that the intensity of a medium earthquake is originally reported as 10%. times I ,. Later this value is revised as 105.5 times I,. The local magnitude M (on the Richter scale) of an earthquake of intensity is given by log (14) Part 1 out of 3 a. Determine the magnitude...
