Earthquakes can be analyzed with the formula: M_2 - M_1 = log A_2/A_1 where M is the magnitude of the earthquake (unit less), and A is the seismograph amplitude of the earthquake being measured (m). The magnitude of an earthquake with triple the seismograph amplitude of a magnitude 5.0 earthquake is?
