Kilauea volcano (Hawaii), activity update: continuing lava flow from 21 July fissure E of Puu Oo

The fissure eruption episode which started on 21 July continues to feed a lava flow that is now branching out to the north more than advancing to the northeast.
HVO's Volcano Watch article summarizes the recent changes:

"Dramatic changes in the long-lived Pu`u `O`o - Kupaianaha have occurred in the past two months. The crater and west side of Pu`u `O`o collapsed, partially refilled with lava, then collapsed again as new vents erupted first uprift then downrift of the cone on June 19 and July 21. Lava is now erupting from the lower end of the July 21 fissure located at the base of the Kupaianaha shield, which was active between 1986 and 1992.
The lava is feeding flows that are moving northeast from the vents across relatively flat ground. The flow is spreading slowly on the north side of the east rift zone, covering lava flows erupted from Pu`u `O`o between 1983 and 1986 and moving into patches of rainforest. It traveled nearly 6 km between July 27 and August 13 before stalling and starting another parallel flow."
