Co-seismic ruptures and deformations recorded by speleothems in the epicentral zone of the Basel earthquake

Abstract:
The study of growth anomalies of speleothems in a karstic environment can provide potential evidence for palaeoearthquakes. These data are used to study the recurrence times of major earthquakes in areas where evidence for historic seismicity is lacking. A study has been carried out in the epicentral area of the 1356 Basel earthquake (epicentral intensity = VII-VIII, macroseismic magnitude = 6.2). The Battlerloch and Dieboldslochli caves, situated in the area of greatest damage, show growth anomalies of speleothems possibly related to a seismic event (several breaks of speleothems and offsets of the axis of the regrowths). The first U/Th disequilibrum measurements by alpha spectrometry show recent ages (less than several tens of thousands of years and probably historic). 14C dating by AMS of carbonate laminations taken on both sides of the anomalies confirm the evidence of a seismic event around 1300 AD. More accurate darings by U/Th TIMS are carried out in order to compare the information provided by the two different dating methods.ResumeL'etude des anomalies de developpement des speleothemes en milieu endokarstique peut permettre de retrouver la trace de paleoseismes. Ces donnees sont utilisees pour etudier les periodes de retour des seismes majeurs dans les regions ou la sismicite historique n'est pas suffisante. Une etude a ete menee dans la zone epicentrale du seisme de Bale de 1356 (intensite epicentrale = VII-VIII, magnitude macrosismique = 6,2). Dans l'aire de degats majeurs, les grottes du Battierloch et du Dieboldslochli ont montre l'existence d'anomalies de croissance des speleothemes pour lesquelles une origine sismique est possible (nombreuses ruptures de speleothemes et decalage de l'axe de croissance des repousses). Les premieres mesures de desequilibres U/Th par spectrometrie alpha indiquent des ages recents (inferieurs a quelques dizaines de milliers d'annees et probablement historiques). Les datations 14C par AMS de carbonates des lamines preleves de part et d'autre de ces anomalies confirment l'empreinte d'un evenement destructif brutal vers 1300 AD. Des datations plus precises par U/Th TIMS sont en cours de realisation afin de confronter les informations apportees par ces deux chronometres
