Evaluation of the LASA, ALPA, NORSAR Long Period Network

Abstract

The report is an expansion of SAAC Report No. 4. The SAAC long period processing methods, based on frequency-wavenumber analysis, are capable of analyzing all the events reported in the LASA and NORSAR Daily Event Summaries within real-time. The capability of LASA to detect Rayleigh waves is azimuth dependent. A comparison of NORSAR and LASA on a data set of Kurile Islands events resulted in a detection of surface waves from all events with M sub b > 4.0 as reported by the LASA Daily Event Summary.
