&lt;/ul&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;&lt;p&gt;Large estuarine and lacustrine deposits in South, S-W, North and NE (Van Vliet-Lano&amp;#235; et al., 2007, 2010, 2018), Iceland allow a fair record of the history of the deglaciation at MIS 3/2, 2/1, late 1 and MIS 6/5e, late 5e periods, consolidated with dating (Guillou et al. 2010, 2019, VVL et al. 2018). Pulsed deglaciations are all under control of orbital forcing and DO events, in association with a modification in the path of the Irminger current. In both systems, the history of the volcanic activity for Gr&amp;#7984;msv&amp;#246;tn, B&amp;#225;r&amp;#240;arbunga, Askja and Hekla volcanoes are very similar, in connection with glacial unloading history. Tectonic activity and seismicity increased temporarily during deglaciation events leading to the discrete activity of inland SDR (Bourgeois et al., 2005, Bergerat &amp; Plateau, 2012). Large earthquakes are restricted to full interglacial conditions (VVL et al., 2005, - on line). Hyaloclastite ridges are ice margin features related to long partial unloading events. The extent of these patterns to full glacial conditions revealed very unstable ice sheets under control of DO events and the associated gravitational spreading, leading to the formation of temporary ice shelves or grounded glacier margins. &amp;#160;&lt;/p&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;&lt;p&gt;Bergerat, F., Plateaux, R. 2012.
