Threemethodsofextractingtheinformationofanomaliesofaprecursorygroupareputforward,i.e.,themathematicalanalysesofthesyntheticinformationofearthquakeprecursors(S),theinhomogeneousdegreeofprecursorygroups(ID)andthevaluesofshort-termandimpendinganomalyinnear-sourcearea(NS).Usingthesemethods,wecalculatetheobservationaldataofdeformation,undergroundfluidandhydrochemicalconstituentsobtainedfromdifferentseismicstationsintheSichuan-YunnanregionandconcludethatthesyntheticprecursoryanomaliesofasinglestrongearthquakewithMs6.0differgreatlyfromthoseofthegroupedstrongearthquakes,fortheanomalousinformationofprecursorygroupsaremoreabundant.ThethreemethodsofextractingthesyntheticprecursoryanomalyandtherelatednumericalresultscanbeappliedintothepracticeofpredictiontothegroupedstrongearthquakesintheSichuan-Yunnanregion.Inhomogeneousdegree(ID)ofsyntheticprecursoryanomalycanbeidentifiedautomaticallybecauseittakesthethresholdofdistributivecharacteristicsoftheanomaliesofprecursorygroupasitscriterionforanomaly.
