Ground motion prediction equations



Introduction

ESEE Report 01-1 ‘A comprehensive worldwide summary of strong-motion attenuation relationships

for peak ground acceleration and spectral ordinates (1969 to 2000)’ (Douglas,

2DamasPIC/old/001a) was completed and released in January 2001. A report detailing errata of this report

and additional studies was released in October 2002 (Douglas, 2002). These two reports were

used by Douglas (2003) as a basis for a review of previous ground-motion prediction equations

(GMPEs). Following the release of these two reports, some further minor errors were

found in the text and tables of the original two reports, and additional studies were found in the

literature that were not included in ESEE 01-1 or the follow-on report. Also some new studies

were published. Rather than produce another report listing errata and additions it was decided

to produce a new report that included details on all the studies listed in the first two reports

(with the corrections made) and also information on the additional studies. This report was

published as a research report of Imperial College London at the beginning of 2004 (Douglas,

2004a). At the end of 2006 a BRGM report was published (Douglas, 2006) detailing studies

published in 2004–2006 plus a few earlier models that had been missed in previous reports.

Finally, at the end of 2008 another BRGM report was published (Douglas, 2008) containing

summaries of GMPEs from 2007 and 2008 and some additional earlier models that had been

recently uncovered.
