      This collective work is the logical conclusion of more than 30 years of French research in Iceland, with the support of various programs and institutions. It has also benefitted from the contribution of a CNRS Thematic School on Iceland, which was held in Brest in 2010 and which was strongly impacted by the eruption of Eyjafjallajökull. This book is the fruit of the work of a group of complementary researchers who are very fond of Iceland. Our thoughts turn to Jacques Angelier who left this basaltic ship a little too early. There are multiple authors to each chapter – with a principal author for each one – in order to provide a multidisciplinary approach to the discussed scientific problems and take into account all our publications up to the most recent ones (2019–2020).

      French research in Iceland began in the mid-1980s, initiated by Françoise Bergerat (Sorbonne Université, formerly Université Pierre et Marie Curie, in Paris) in search of an “emerging oceanic ridge”, in collaboration with Jacques Angelier†, then Catherine Homberg. Very quickly, this collaboration was extended to Icelandic colleagues, Águst Guðmundsson (London), Kristjan Sæmundsson, Ragnar Stefánsson and Sigurdur Rögnvaldsson †. The first work focused on the analysis of brittle deformations and then turned to sismotectonics.
