Short Period Guided Waves Over Oceanic and Continental Paths
Abstract
Task A: 1--Evaluate the usefulness of Pg and Lg to estimate yield for Eurasian and Africa events, 2--Investigate possible caused of amplitude variation (i.e. source and recording site geology), and 3--Analyze the regional phases for use in discrimination and yield estimation; Task B: 1--Continue the analysis of data from Wake Island Hydrophone Array in cooperation with personnel at Hawaii Inst. of Geophysics and assist in guiding the operation of the array, 2--Conduct comparative studies of (long-range) oceanic Pn/Sn and continental Lg (Pg) using, especially, data from the Catskill Seismic Array and the Wake Array, in comparison with theoretical seismograms for different source types, focal depth, and velocity structures, and 3--Evaluate the Wake and Catskill Arrays in terms of signal coherence and detection capability, also compare them with other high quality continental stations and the DARPA/NORDA MSS; Task C: 1--Install, maintain, and operate high quality three component broad band digital seismographs in the Stone Ridge, NY area, and 2--Development analysis techniques and software to obtain source and propagation path characteristics from broad band three component digital data.
