Japan's Tōhoku earthquake in 2011 had a magnitude of 9.0 (Figure below). Earthquake and tsunami damage in Japan, 2011. The Richter scale uses the measurements of seismic waves as recorded on seismographs. For the first time, earthquake magnitude was defined independently of the effects or damage it caused. Calculating Richter Magnitude. Richter derived a formula to calculate the magnitude of an earthquake. It’s expressed as: M L = log A – log A 0. Here:In comparison with other large earthquakes around the world, the 2011 Japan quake and tsunami – in which more than 22,000 people were killed or went missing – registered a magnitude of 9.1.Earthquake - Magnitude, Seismology, Epicenter: Earthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs.
