Abstract : A temporary deployment of eight broadband seismographs in the Arabian Shield and one on the Arabian Platform has shown that the shield sites are among the quietest in the world, with noise levels generally only slightly above the low-noise model. Distinct path-related differences in the recording of regional events allow the assignment of general source regions upon mere visual examination of the recordings. To date, clear regional phase are observed on intra-Arabian Plate paths from events in the Zagros region. Events occurring in the Gulf of Aqaba and propagating mostly in the Arabian Shield show a clear but weak P sub n phase and prominent L sub g. Events originating in the Arabian Sea show clear body waves but no waves but no L sub g.
