It is impossible to know for sure what happens next in TFZ. But the stress is high in this area of Iceland according to GPS measurements. As some of the fault lines in TFZ are locked in place, while the whole system remains on the move otherwise. This builds up stress levels on the fault lines that are locked and unable to move in accordance with other tectonic movements in the area. This lock is then released in large earthquakes in TFZ that happen once to twice a century in this area. Now it is possible that it is time for new large earthquake in this area. But when is impossible to know for sure at the moment.
Some rock collapse has happened following the Mw5.6 earthquake on TFZ. This has been reported in local news media in Skagafjörður.
