11 To compare intensities of earthquakes use the formula log₁0 = R₁ - R₂ where I, is the intensity of the quake being measured, I₂ is the intensity of the reference quake and R₁ - R₂. How many times more intense is an earthquake measuring 7.2 on the Richter scale than an earthquake measuring 5.9 on the Richter scale?
