<!--!introduction!--> During the last decades, more than 30 relatively deep boreholes were drilled onshore in Norway. According to thermal logging, the highest temperatures (up to 28.2 °C at 800 m depth) were observed in the boreholes, located on the Svalbard archipelago which has signs of Quaternary magmatic activity. In contrast, the tectonically quiescent northernmost Norway is characterized by the lowest measured temperatures (slightly more than 9 °C at 650 m depth). The highest temperature in Central Norway (22.2 °C at 800 m depth) was measured on the small island close to the deep sedimentary basins in the Norwegian Sea. The southwestern part of Norway shows relatively low temperatures (e.g., 17.6 °C at a depth of 800 m near Stavanger). These low temperatures can be a result of groundwater flow that cools down the uppermost crust in this region. The area around the Oslo Fjord shows a complicated thermal pattern in the subsurface. There, at 800 m depth, the measured temperature ranges from 16 to ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
