The Richter scale, which measures the magnitude of earthquakes, is a common logarithmic value of earthquake intensity (i.e., the energy released by an earthquake). Obviously, the higher the magnitude, the greater the intensity of the earthquake. For example, the earthquake in Japan in 1923 was of magnitude 8.9, the earthquake in San Francisco in 1906 was of magnitude 8.3, and the earthquake in 1989 was of magnitude 7.1. Calculate how many times greater the intensity of the earthquake in Japan in 1923 was compared to the 8.3 magnitude and 7.1 magnitude earthquakes? (Take $\lg 2=0.3$)
