    Meanwhile, major earthquakes such as the 1994 offshore Sanriku earthquake and the 1995 Great Hanshin Earthquake revealed issues like wide variability in damage in areas with intensities 5 and 6, as well as delays in determining intensity 7 (which required field surveys by the JMA’s mobile observation team). These issues highlighted the need ...

    en.wikipedia.org/wiki/Seismic_magnitude_scales

    K (from the Russian word класс, 'class', in the sense of a category [57]) is a measure of earthquake magnitude in the energy class or K-class system, developed in 1955 by Soviet seismologists in the remote Garm region of Central Asia; in revised form it is still used for local and regional quakes in many states formerly aligned with the ...

  4. Modified Mercalli intensity scale - Wikipedia

    en.wikipedia.org/wiki/Modified_Mercalli...

    The Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth. (The "M w" scale is ...
