Introduction:
The2006YunnanYanchunearthquakeswarmwasoneofthemostsignificantseismiceventsintheregion,causingextensivedamageandposingagravethreattothesafetyoflocalresidents.Thisearthquakeswarmcomprisedseveralstronggroundmotions,whichwarrantanin-depthstudytobetterunderstandtheircharacteristics,causes,andpotentialimpacts.Inthisstudy,weaimtoprovideananalysisoftheemergencyobservationsandresearchconductedduringtheaftermathoftheearthquakeswarm.
Methodology:
1.SeismicDataCollection:Thelocalseismicmonitoringnetworkrecordedandcollecteddataongroundmotions,includingacceleration,velocity,anddisplacement.Thedatawereacquiredfromdigitalandanalogseismicstationslocatedneartheepicenter.
2.FieldInvestigation:Emergencyteamsweredispatchedtotheaffectedareastoconductsurveysandgathervaluableinformationonthegroundshakingeffects,buildingresponse,infrastructuredamage,andcasualties.
3.StructuralHealthMonitoring:Seismicinstrumentswereinstalledincriticalstructuressuchasbridges,dams,andhigh-risebuildingstomonitorandevaluatetheirdynamicresponseduringtheearthquakeswarm.
ResultsandDiscussion:
1.CharacteristicsofStrongGroundMotions:Analysisofseismicdatarevealedseveralimportantcharacteristicsofthestronggroundmotions,includingpeakgroundacceleration(PGA),peakgroundvelocity(PGV),frequencycontent,andduration.Thedatashowedthatthegroundmotionsvariedspatiallyandtemporally,highlightingthecomplexityoftheearthquakeswarm.
