Most of the papers in this book were presented at the workshop on "Deformation and Gravity Change: Indicators of Isostasy, Tectonics, Volcanism and Climate Change", which took place at the Casa de los Volcanes on Lanzarote, Spain, during March 1-4, 2005. It was jointly organized and supported by the International Association of Geodesy (IAG), the Spanish Ministry of Education and Science, the Spanish Council for Scientific Research and the Cabildo Insular de Lanzarote.
The workshop also served as the first meeting of the members of the IAG Working Group ICCT2 on "Dynamic Theories of Deformation and Gravity Fields". This subject reflects the major developments in geodynamics during the last decade, when temporal variations of the deformation and gravity fields recorded by the geodetic measuring techniques and reflecting isostatic, tectonic or volcanic processes in the earth’s interior as well as hydrologic or oceanographic processes on its surface have gained ever increasing importance.
