This morning, a lava flow escaped from the Geldingadalir valley at its southern rim, crossed the hiking trail A (which was leading to the observation hills southeast of the active cone), and made its way to the already existing lava flow field in the Nátthagi valley to the SE.
Geldingadalir valley by now is largely filled with lava flows, which continue to pile up layer by layer, and, importantly, by inflation of the still liquid lava body under the mostly solidified crusts. As it thus gradually increases the height of the surface, it allows lava to spill over increasingly wide sections of the enclosing rims.
As to the activity, effusion of lava continues at more or less constant pace, but the pulsating, "geyser-like", rhythmic behavior of strong up-welling and fountaining roughly every 10 minutes has decreased or stopped in favor of a more constant flux of lava from the vent.

Authorities carried out aerial surveys to check if hikers were trapped in the now cut-off areas, and later decided to temporarily close access to the eruption site.
