Earthquake magnitude vs acceleration
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. Site Coordinates WebEarthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs. (The types and nature of these waves are described in the section Seismic waves.)
