Textbook Question
Chapter 5.4, Problem 135E
Earthquakes 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
- On July 26, 1963, an earthquake in Yugoslavia had a magnitude of 6.0 on the Richter scale, and on August 19, 1977, an earthquake in Indonesia measured 8.0. Find the intensity x for each of these earthquakes if I0= 1.
- How many times more intense was the Indonesian earthquake than the Yugoslavian earthquake?

- Richter Scale The Richter scale provides a measure of the magnitude of an earthquake. In fact, the largest Richter number M ever recorded for an earthquake was 8.9 from the 1933 earthquake in Japan. The following formula shows a relationship between the amount of energy released and the Richter number. M=23logE0.007, Where E is measured in kilowatt-hours. Source: Mathematics Teacher. a. For the 1933 earthquake in Japan, what value of E gives a Richter number M=8.9?. b. If the average household uses 247 kWh per month, how many months would the energy released by an earthquake of this magnitude power 10 million household? c. Find the rate of change of the Richter number M with respect to energy when E=70,000 kWh. d. What happens to dM/dE as E increases?arrow_forwardThe function f(x)=5x is an exponential function with base______; f(2) =_______, f(0) =______, f(2) =_______, and f(6) =_______.arrow_forwardEarthquake Intensity The magnitude of an earthquake, measured on the Richter scale, is given by RI=logII0, where I is the amplitude registered on a seismograph located 100 Km from the epicenter of the earthquake, and I0 is the amplitude of a certain small size earthquake. Find the Richter scale ratings of earthquakes with the following amplitudes. a. 1,000,000I0 b. 100,000,000I0 c. On June 15,1999, the city of Puebla in central Mexico was shaken by an earthquake that measured 6.7 on the Richter scale. Express this reading in terms of I0. Source: Exploring Colonial Mexico. d. On September 19,1985, Mexicos largest recent earthquake, measuring 8.1 on the Richter scale, killed about 10,000 people. Express the magnitude of an 8.1 reading in terms of I0.Source: History.com. e. Compare your answers to part c and d. How much greater was the force of the 1985 earthquake than the 1999 earthquake? f. The relationship between the energy E of an earthquake and the magnitude on the Richter scale is given by RE=23logEE0, where E0 is the energy of a certain small earthquakes. Compare the energies of the 1999 and 1985 earthquakes. g. According to newspaper article, "Scientists say such an earthquake of magnitude 7.5 could release 15 times as much energy as the magnitude 6.7 trembler that struck the Northbridge section of Los Angeles" in 1994.Source: The New York Times. Using the formula from part f, verify this quote by computing the magnitude of an earthquake with 15times the energy of a magnitude 6.7 earthquake.arrow_forward
