Rayleigh waves from each event in the ISM epicenter list were sought at the LASA, ALPA, and NORSAR long period arrays. The method used FKCOMB, a program which computes a three dimensional Fourier transform in frequency-wave number space for overlapping four minute windows. The paper discusses the Rayleigh wave detection rates, missed signal rates, and false alarm rates measured at these three long period arrays during the International Seismic Month.
