Proceedings of the 12th International INQUA meeting on paleoseismology, active tectonic and archaeoseismology

Northern Iceland contains the ideal tectonic and volcanogenic conditions for geothermal resources due to the interactions between the Northern Volcanic Zone (NVZ) and the Tjörnes Fracture Zone (TFZ). The Tjörnes Fracture Zone consists of three WNW- trending seismic structures (Metzger & Jonsson, 2014; Karson, 2017) that are categorized as semi- independent transform zones in varying staged of development; the Husavik-Flatey Fault (HFF), the Grimsey Oblique Rift (GOR) and the Dalvik Lineament (DL) (e.g. Saemundsson, 1974; Einarsson, 1979; Horst et al., 2018). The Dalvik Lineament represents the southernmost boundary of the TFZ, running parallel to the HFF approximately 30 km to the south within the Troll Peninsula (Icelandic; Trollaskagi; Rögnvaldsson et al., 1998), and is the primary seismotectonic feature of interest for this study (Figure 1). Fig. 1: Preliminary map of landslides and macro seismic events on the Troll Peninsula (Trollaskagi) in North Iceland. The approximate location of the Dalvik Lineament (DL) is shown with the blue line. Note the correlation between landslides and the DL. Hot springs are indicated by orange triangles. Inset: The three main strike slip faulting areas in North Iceland are shown, from north to south; Grimsey Oblique Rift (GOR), Husavik- Flatey Fault (HFF) and the DL.
