Analysis of Coda and Multipath Propagation of Rayleigh Waves at NORSAR.

Abstract

Frequency-wavenumber analysis of coda of 40 and 20 sec Rayleigh waves recorded at NORSAR shows that 40 sec period coda drops off faster vs. time while the resolving power of the array is better at 20 sec. Multipath arrivals with as much as 40-60 degrees are frequently identified, and travel path solutions for some events are proposed. As an example, 20 sec Rayleigh waves from a nuclear explosion are identified in the presence of an interfering event.
