A magnitude 9.0 earthquake, which rarely occurs, releases over a million times as much energy as a magnitude 5.0 earthquake. Ranking Earthquake Intensity. Earthquake intensity is very different from earthquake magnitude. Earthquake intensity is a ranking based on the observed effects of an earthquake in each particular place. Repeated earthquakes and their associated fault movements have formed the major mountain ranges of New Zealand. Faults that fall outside the traditional definition of 'active' can still be capable of generating earthquakes. These faults can - and have - contributed to major events, such as the 2016 magnitude 7.8 Kaikōura earthquake.Earthquake intensity measures (IMs) are fundamental for describing the important characteristics of ground motion in a quantitative manner. Many IMs have been proposed …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.
