A good example of this difference is a comparison of the devastating 2011 Christchurch earthquake and a much larger magnitude earthquake that struck the area in November 2016. While the February 2011 quake in Christchurch rated a 6.3 on the moment magnitude scale, it devastated the area, killing 185 people and destroying multiple large buildings .

Moment magnitude scale. The moment magnitude scale ( MMS; denoted explicitly with Mw or Mw, and generally implied with use of a single M for magnitude [1]) is a measure of an earthquake 's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. A magnitude 7.0 releases about 32 × 32 = 1024 times as much energy as a magnitude 5.0 earthquake. A magnitude 9.0 earthquake, which rarely occurs, releases over a million times as much energy as a magnitude 5.0 earthquake.
