Tjornes fracture zone to go? Volcanic activity soon?

The TFZ looks very active at the moment with several swarms over the last few days.

Tjörnes Fracture Zone (TFZ)
Overview

This fracture zone, located in the North of Iceland, is currently showing signs of activity.( [link to hraun.vedur.is] The zone has three major seismic areas, the Dalvik Fault ,the Husavik-Flatey Fault and the Grismsey Fault and is considered to be a transform fault, as San Andreas.( what about the Húsavík fault and the Guðfinnugjá fault?) It can be considered as a major BOT (Broad Oceanic Transform)fault and experts think that the Grismsey Fault is the latest active structure.( [link to www.agu.org] Doubts remain as to if there is an underground magma chamber( [link to cat.inist.fr] the southern part of the Grimsey Alignment.
