Iceland is a part of a large geological structure, consisting of the Reykjanes Ridge and the bathymetric Elliptical Plateau of Iceland. In turn, Reykjanes Ridge is marked by V-shaped ridges. We can try to look closer at the context:
The V-shaped ridges converge at the point where the alignment changes to north-south. This brings us closer to the exact consistency between the convection rolls and the Icelandic Elliptical Plateau, with a NS-axis through Eyjafjallajökull, Hekla and Hveravellir, along with the (volcanically extinct but still seismically active) Skagafjördur Volcanc Belt, which is connected with the Kolbeinsey Ridge north of Iceland.
A map from the Icelandic Land Survey is superimposed on the Google Map, and some of the measured drift vectors shown with black arrows. These vectors show the current tectonic drift directions of Iceland. The country is mainly drifting northwards, but being divided at the same time to the NW and NE. This is more complex than the old version of saying that the two halfs of Iceland should be drifting opposite to the other to the west and east. The true description of tectonic drift of Iceland is more complicated than that.
