2. If a third earthquake is 400 times larger in amplitude than the Alberta quake, then what is the magnitude of the third earthquake? 1. The formula for the Richter magnitude, M, of an earthquake is M = log(A) Where A is the amplitude of the earthquake and A, is the amplitude of a standard earthquake with a magnitude of 0. In 2011, an earthquake occurred off the Pacific coast of the Tōhoku region of Japan. This earthquake, which measured 9.0 on the Richter scale, is one of the five most powerful earthquakes in the world since modern record-keeping began in 1900.
