<!--!introduction!--> Accurate seismotectonic studies on and around Spitsbergen, European Arctic, are impeded by a number of difficulties. The largely glaciated environment and the geographic distribution of land and sea restrict geotectonic mapping, as well as the deployment of dense, local seismic networks. The nature of tectonic seismicity in the region, which is episodic and dominated by moderate to low event magnitudes, imposes additionally its own challenges. So far, the best studied activity has been the Storfjorden 2008-2016 earthquake series (Mw 6.1, 21 February 2008; Mw 5.1, 29 March 2016) and background seismicity in the offshore area east of southern Spitsbergen, and to a lesser extent, seismicity in Heerland, on central Spitsbergen (mb 5.5, 18 January 1976). Despite the aforementioned challenges, the improvement of the regional seismic network from 2010 onward, has been offering enhanced insight into Svalbard seismotectonics, in particular in areas best covered by seismic station ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
