It appears that there is a chance of a dike intrusion in Hamarinn volcano (Loki-Fögrufjöll area). What suggest that there is a dike intrusion starting in Hamarinn volcano is a earthquake swarm that is unusually dense and has a really narrow area. But normal earthquake swarms usually spread over a small area in the align of the fault line.
How this is developing is a good question. But due to lack of earthquakes it is hard to know for sure at the moment. But at the moment it is worth to keep eye on Hamarinn volcano area.
