Using a dense GNSS dataset coupled with PSInSAR analysis, we provide new evidence of sinistral simple shear driven by a NNE\u2010SSW first\u2010order tectonic lineament. PSInSAR vertical velocities corroborate qualitatively the GNSS strain\u2010rate field, showing uplift\/subsidence where the GNSS data indicate contraction\/extension. We propose the presence of a small block to the W of Lisbon moving independently toward the SW with a relative velocity of 0.96\u00a0\u00b1\u00a00.20\u00a0mm\/yr, whose boundaries are part of a complex and as yet poorly constrained strike\u2010slip fault system, possibly rooting at depth into a simpler basement fault. Comparison between geodetic and seismic moment\u2010rates indicates a high seismic coupling. We show that the contribution of intraplate faults to the seismic hazard in the LMA is more important than currently assumed.<\/jats:p>","DOI":"10.1029\/2021gl096862","type":"journal-article","created":{"date-parts":[[2021,12,13]],"date-time":"2021-12-13T16:07:47Z","timestamp":1639411667000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Interseismic Strain Accumulation Near Lisbon (Portugal) From Space Geodesy"],"prefix":"10.1029","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0371-3682","authenticated-orcid":false,"given":"J.
