daves_notes_on_ratios_of_source_spectra_v1.2.pdf. Equations for ratios of single-corner-frequency source spectra, for use in determining stress parameters from ratios of motions from two closely located events recorded at the same station (the "empirical Green's function" method).

dont_call_them_attenuation_relations.pdf (07/21/2006). These notes are an appeal to do away with the term "attenuation relations". These notes were repeated in section A.1 of Appendix A (). of Boore and Atkinson (2007), in which I proposed the term "Ground-Motion Prediction Equations", or "GMPEs". This term seems to have caught on and is now being used globally.
