Three sets of SAR data acquired during the years 1992\u20132010 from ERS-1\/-2 and ENVISAT, and 2011\u20132014 from TerraSAR-X satellites were used in conjunction with the Small Baseline Subset (SBAS) and persistent scatterers (PS) high-resolution multi-temporal interferometry (InSAR) techniques to provide maps of line-of-sight displacements. The satellite-based remote sensing results were combined with results derived from classical methodologies (i.e., diachronic cartography) and field research to study possible trends in developments over former clay pits, landfill excavation sites, and industrial parks. The ground displacement trend patterns were analysed using several linear and nonlinear models, and techniques. Trends based on the estimated ground displacement are characterised by long-term memory, indicated by low noise Hurst exponents, which in the long-term form interesting attractors. We hypothesize these attractors to be tectonic stress fields generated by transpressional movements.<\/jats:p>","DOI":"10.1038\/srep43762","type":"journal-article","created":{"date-parts":[[2017,3,2]],"date-time":"2017-03-02T10:14:45Z","timestamp":1488449685000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Long-term ground deformation patterns of Bucharest using multi-temporal InSAR and multivariate dynamic analyses: a possible transpressional system?"],"prefix":"10.1038","volume":"7","author":[{"given":"Iuliana","family":"Arma\u015f","sequence":"first","affiliation":[]},{"given":"Diana A.","family":"Mendes","sequence":"additional","affiliation":[]},{"given":"R\u0103zvan-Gabriel","family":"Popa","sequence":"additional","affiliation":[]},{"given":"Mihaela","family":"Gheorghe","sequence":"additional","affiliation":[]},{"given":"Diana","family":"Popovici","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2017,3,2]]},"reference":[{"key":"BFsrep43762_CR1","doi-asserted-by":"publisher","first-page":"1562","DOI":"10.1002\/esp.1848","volume":"34","author":"C Casta\u00f1eda","year":"2009","unstructured":"Casta\u00f1eda, C., Guti\u00e9rrez, F., Manunta, M. & Galve, J.
