The models yields stress concentrations for today at the western (about 21.4W, 64N) and eastern end (about 18.8E, 64N) of the SISZ and some smaller spots inside the SISZ around (150 to 160, 10) in model coordinates, i.e. around (20W, 64N). As the stress build-up by plate motion is very low in these models, the uncertainty in time is very large in the so-called "improved model" and still large in the "short rupture model".
The high stresses at the ends of the SISZ are debatable. On one hand, there was no earthquake above M=6.5 in both areas since 1706, on the other hand, the recent seismicity in both areas is high with events M5 (1987 in the east at Vatnafjöll and in 1998 in the west, near Hengill).
