Note on scaling of peak ground acceleration and peak ground velocity with magnitude [PDF]
Geophysical Journal International, 2002 SUMMARY The theoretical scaling of near-field peak ground acceleration and peak ground velocity with moment magnitude, Mw, is found using an L model of rupture. This scaling matches well with the magnitude scaling of recent attenuation relations.
