75 years of applied geophysics in Lower Saxony describes a long-standing, complex know-how that we can be proud of at LIAG and in Hannover. We would like to celebrate this with panel discussions and keynotes on socially relevant topics within our research areas of groundwater, geohazards and georeservoirs as energy sources and energy storage on November 15, 2023 as part of the "November of Science" at the aufhof in Hannover. On November 16, 2023, interested people can experience geophysics at first hand: Various experiments and exhibits will be set up and explained for this purpose at the aufhof in Hannover - including how groundwater deposits and raw materials are researched with the 2.5-meter measuring drone, or how fault zones and thus earthquake potentials are created, or how electrical conductivity and thermal conductivity work and why this is important for topics such as groundwater salinization and geothermal energy.
