Abstract : The objective of this project has been to retrieve useful seismic waveform data from an unwieldy format and create an easy-to-use data set for seismic research. The results are over 250 'event directories' for regional events in and near Iran. Each 'event directory' is a standalone data product including short-period seismic waveforms and CSS3.0 database tables containing the auxiliary information necessary and useful to read and interpret the waveforms. These data are available to interested researchers through an anonymous FTP account. The waveform data are from two seismic stations located in Iran and operating in the late 70's: The Iranian Long Period Array (ILPA), located near Tehran, and MMO, (Mashhad, Iran), located 800 km east of ILPA. Over 1700 phases were timed and identified on the ILPA and MAIO waveforms. This report focuses on how the data set was constructed and presents some analysis observations. An appendix lists the seismic bulletin summarizing all parameters related to each event. Information derived from this data set by researchers such as Sweeney, Baumgardt and Alexander and others, will certainly be critical to the understanding of propagation of regional seismic phases in and near Iran. Results based on the ILPA/MAIO should be part of the knowledge base currently being constructed by the DOE.
