After the resumption of the effusive eruption at the current site one week ago, the activity shows signs of increasing.
It proves a formation of new lava flows in the upper part of the Nátthagi valley that have continued to fill up the valley.
The effusion of lava continues at elevated discharge rate. This is most likely reflecting at higher pace of the lava that overtook the artificial dam, crossed the hiking trail and leading towards the southern ring road.

Nátthagi valley by now is largely filled with lava flows.
