In the latest hazard map prepared by the Iceland Met Office, zones filled in darker colors indicate a greater risk for eruptive activity, with purple representing the highest probability. Although the probability of a vent opening in Grindavik has lowered, considerable risk still exists. The red lines within the purple area mark the locations of the two currently active fissures, and the extent of the lava flow as of December 19 at 19:35 UTC is shown in dark purple on the map.
