The Húsavík–Flatey fault (HFF) network is one of the seismically most active zones in Iceland. This complex fault system crosses from off-shore to on-shore directly underneath the town of Húsavík and consists of multiple right-lateral strike slip segments distributed across ~100 km. The HFF hosted several historical earthquakes with M>6. The moment it accumulated since last major earthquakes (two M6.5 events in 1872) may result in an earthquake of magnitude 6.8 to 7 (Metzger & Jonsson, 2014), posing a high seismic risk to Húsavík’s community, flourishing tourism and heavy industry. However, seismic hazard assessment (SHA) remains challenging.
