Mantle plume-mid-ocean ridge interaction in the North Atlantic -- Tectonic framework -- Crustal structure of Iceland -- Volcano dynamics -- The plate-spreading deformation cycle -- Breaking the crust: Seismicity and faulting -- Glacial isostasy and sea-level change: Rapid vertical movements and changes in volcanic production rates -- Iceland geodynamics: Outlook. This book provides a summary of geodynamic results from Iceland that presently are found in a great number of scientific articles, but have not been collected before in a book. The ever increasing number of scientists interested in geology and geophysics of Iceland should find the book a "must" to gain knowledge about previous work and the status of knowledge about Iceland.
