During the period 1880\u20131906, moderate to strong seismic activity with three earthquakes magnitude ML \u2265 6 occurred on the NW-SE striking Ka\u0161ina Fault and since then, the area has not experienced earthquakes exceeding magnitude ML = 5. In order to estimate the ongoing interseismic strain accumulation along the fault, we analyze Advanced Land Observing Satellite (ALOS) Phased Array L-band SAR (PALSAR) and Environmental Satellite (Envisat)-Advanced Synthetic Aperture Radar (ASAR) datasets acquired over the period 2007\u20132010 and 2002\u20132010, respectively. The data were analyzed using small baseline interferometry (SBI) technique and indicate very slow surface deformations in the area, within \u00b13.5 mm\/year, which are in a good agreement with previous geodetic studies. Interseismic strain accumulation analysis was conducted on two 14 km long segments of the Ka\u0161ina Fault, seismically active in the South and stable in the North. The analysis indicates an ongoing interseismic strain accumulation of 2.3 mm\/year on the Southern segment and no detectable strain accumulation on the Northern segment. Taking into consideration the lack of moderate to strong seismic activity in the past 113 years combined with the preliminary geodetic analysis from this study, we can conclude that the Southern segment of the Ka\u0161ina Fault has the potential to generate earthquake magnitude Mw &lt; 6.<\/jats:p>","DOI":"10.3390\/s19224857","type":"journal-article","created":{"date-parts":[[2019,11,7]],"date-time":"2019-11-07T11:17:25Z","timestamp":1573125445000},"page":"4857","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Surface Deformation Analysis of the Wider Zagreb Area (Croatia) with Focus on the Ka\u0161ina Fault, Investigated with Small Baseline InSAR Observations"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1534-4992","authenticated-orcid":false,"given":"Marin","family":"Govor\u010din","sequence":"first","affiliation":[{"name":"Faculty of Geodesy, University of Zagreb, Ka\u010di\u0107eva 26, HR-10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bo\u0161ko","family":"Pribi\u010devi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Geodesy, University of Zagreb, Ka\u010di\u0107eva 26, HR-10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4969-0642","authenticated-orcid":false,"given":"Shimon","family":"Wdowinski","sequence":"additional","affiliation":[{"name":"Department of Earth and Environment, Florida International University, 11200 SW 8th Street, Miami, FL 33199, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"283","DOI":"10.1016\/S0040-1951(98)00173-5","article-title":"Tectonic activity in the Croatian part of the Pannonian basin","volume":"297","author":"Kuk","year":"1998","journal-title":"Tectonophysics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"212","DOI":"10.1016\/j.tecto.2008.12.005","article-title":"Seismicity and earthquake focal mechanisms in North-Western Croatia","volume":"465","author":"Herak","year":"2009","journal-title":"Tectonophysics"},{"key":"ref_3","first-page":"269","article-title":"Seismic zoning of Croatia","volume":"18","author":"Herak","year":"1999","journal-title":"Nat.
