Enlargement of the active rift during glaciations
During the last glaciation, an ice sheet covered Iceland approximately 1000 m thick. A reconstruction of the ice flow lines shows that the ice sheet was partly drained through fast-flowing streams. The major drainage routes correlate with locations of geothermal anomalies, suggesting that ice stream...
