South Iceland Seismic Zone Polygon

I mentioned the SISZ earlier, as it is one of the clearest examples of polygons marked by the mantle convection cells. The balanced conditions within the ductile part of the tectonic plate lead to earthquake faults exactly in between the symmetrical lines around it to the NW, NE, SW and SE. The faults are therefore aligned NS.

SISZ - South Iceland Seismic Zone explaination

In this way it becomes much easier to analyze every feature of earthquake zones of this kind. The reasons for pressure directions become clear. In this case, pressure is exerted from NE and SW. NS-faults are drawn with 715 meters interval along the 64th parallel.
