SEA99 - Ground Motion Prediction Relation
SEA99
The ground motion prediction relation SEA96 has been superseded by a new
relation SEA99. SEA99 should be used in preference to SEA96. SEA99 was
derived from a larger data set than was SEA96, minor errors in the SEA96
data set were corrected in the SEA99 data set, and an improved analysis
method was used to derive the SEA99 coefficients. The relation SEA99 is
published in:
"SEA99 - A Revised Ground Motion Prediction Relation for Use in Extensional
Tectonic Regimes," by Spudich, P.; Joyner, W. B.; Lindh, A. G.;
Boore, D. M.; Margaris, B. M.; Fletcher, J. B., Bulletin of the
Seismological Society of America, 1999, v. 89, pp. 1156 - 1170.

relation SEA99 can be downloaded below in either ascii text or Excel formats:
