Types of Magnitudes Magnitude is express[63K 5.4M views 5 years ago In this 5th episode, we compare the poweAn emergency alert warning people in the Earthquake duration magnitude. The concept of Earthquake Duration Magnitude – originally proposed by E. Bisztricsany [1] in 1958 using surface waves only - is based on the realization that on a recorded earthquake seismogram, the total length of the seismic wavetrain – sometimes referred to as the CODA – reflects its size. 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.}
