Earthquake activity in Reykjanes volcano is now mostly continues but it peaks with earthquake activity swarm like this one every few days to weeks. How much earthquake activity depends on how magma inflow is taking place at 3 to 10 km depth. It seems that flow rate is different between hours to days. Since the earthquake activity is continuous in Reykjanes volcano there is a permanent risk of magnitude Mw5,0 to Mw6,0 earthquake in this area.
