The pattern of surface deformations in the Dąbrowa Basin (Poland) based on PSInSAR analysis

Abstract

As so ci ate Ed i tor: Tomis³aw Go³êbiowski Slow, long-term ground de for ma tions in the D¹browa Ba sin (south ern Po land) were iden ti fied based on ERS-1, ERS-2 and ENVISAT Syn thetic Ap er ture Ra dar (SAR) im ages that were pro cessed by means of Per ma nent Scat terer SAR In ter fer om etry (PSInSAR). The D¹browa Ba sin is a re gion where two ma jor fac tors can af fect sur face sta bil ity: in ten sive coal ex ploi ta tion and neotectonic pro cesses. In this study, in or der to clar ify the or i gin of sur face de for ma tions, the au thors pro pose ap ply ing a newly de vel oped al go rithm of spatio-tem po ral PSInSAR data anal y sis. This anal y sis re vealed that sub si dence is a char acter is tic fea ture of the D¹browa Ba sin. A sig nif i cant cor re la tion ex ists be tween slow, long-term ground de for ma tions and the lo ca tion of the main tec tonic struc ture of this re gion. The pro posed spatiotemporal anal y sis of the PSInSAR data ad di tion ally showed some de gree of cor re la tion be tween min ing ac tiv ity and the stud ied de for ma tions. This in ter con nec tion is a sig nif icant achieve ment of this study since the de for ma tion val ues de ter mined by means of PSInSAR were iden ti fied in ear lier works solely on the ba sis of D¹browa Ba sin neotectonics.
