    Late 2019 and early 2020 unusual earthquake activity and the
    start of an uplift of the land around the mountain Þorbjörn drew
    attention to the Reykjanes Peninsula, in southwest Iceland. The
    events could indicate that a new rifting episode is about to start.
    The last volcanic eruption in this area occurred around 800
    years ago. This paper is a report of a study of the Reykjanes fissure swarm. The fissures of the Reykjanes fissure swarm were mapped, the
    magnitude of the throws calculated and multiple cross sections
    were drawn. The fissure swarm is at its maximum about 8.5 km
    wide and has a maximal cumulative throw of about 110 m. To
    create a throw of that size about 4 to 8 rifting episodes like the
    ones in Krafla (1975-1984) and Dabbahu (2005-2010) would
    have had to occur in the last 14 thousand years. The different
    data from the study made it possible to outline what the
    different stages of a rifting episode are and how the fissure
    swarm behaves in case of dike intrusions. They also indicate
    that there is a higher risk of damage because of fault
    movements on the Grindavíkurvegur and Nesvegur roads than
    on Reykjanesbraut, should another rifting episode occur.
