Earthquake magnitude vs acceleration
WebMagnitude scales, like the moment magnitude, measure the size of the earthquake at its source. An earthquake has one magnitude. The magnitude does not depend on where the measurement is made. Often, … Web• Horizontal Peak Ground Acceleration (HPGA or PGA) , in units of g, where g is the acceleration of gravity. • Deaggregated mean earthquake moment magnitude (M or Mw) for the design PGA, and the • Deaggregated mean site-to-source distance ( R or Rrup, in km) for the 1.0 second period design spectral acceleration.
