Waveform Data Collection for Source Inversion Studies

Abstract : The primary purpose of this contract on seismic waveform collection activities is to provide a data base of digital long period seismograms from selected large underground explosions, to be used in source inversion research. An added task requires the collection of digital Lg phases to be used in magnitude studies. Digital seismograms in this data base are collected by hand-digitizing analog seismograms from stations in the World Wide Standard Seismograph Network and by collecting existing digital data from stations in the Atomic Energy Detection System (AEDS). A number of waveforms have also been hand-digitized from AEDS analog recordings. Keywords: Digital seismic data base; Hand-Digitized Seismic Data seismic waves.
