Mapping crustal S—wave velocity structure with SV—component receiver function method-中国期刊网

摘要 Inthisarticle,weanalyzethecharactersofSV-componentreceiverfunctionofteleseismicbodywavesanditsadvantagesinmappingtheS-wavevelocitystructureofcrustindetail.Similartoradialreceiverfunction,SV-componentreceiverfunctioncanbeobtainedbydirectlydeconvolvingtheP-componentfromtheSV-componentofteleseismicrecordings.OuranalysesindicatethatthechangeofamplitudeofSV-componentreceiverfunctionagainstthechangeofepicentraldistanceislessthanthatofradialreceiverfunction.Moreover,thewaveformofSV-componentreceiverfunctionissimplerthantheradialreceiverfunctionandgivesprominencetothePSconvertedphasesthatarethemostsensitivetotheshearwavevelocitystructureintheinversion.ThesynthetictestsshowthattheconvergenceofSV-componentreceiverfunctioninversionisfasterthanthatoftheradialreceiverfunctioninversion.Asanexample,weinvestigatetheS-wavevelocitystructurebeneathHIAstationbyusingtheSV-componentreceiverfunctioninversionmethod.
