The two new lava flows from Puʻu ʻŌʻō crater which emerged as surface breakouts from the partially blocked old lava tube on 24 May continue to be active, but have only advanced a bit during the past days.

The feature in the center foreground is a perched lava pond that formed in July 2014, but was refilled by new lava from the northern breakout in recent days. (image: HVO)
The old lava tube is still "working" as well (however, at presumably much reduced rate of lava throughput) and has been feeding scattered breakouts on the older June 27th lava flow field further to the northeast. At the moment, all active lava is within 5.4 km from the vent, far from inhabited areas to which it poses no threat.
The summit lava lake remains active in Halema'uma'u crater. Its level varied slightly and is currently 31 m (102 ft) below the Overlook crater rim.
According to HVO, "rates of seismicity are at background levels, with episodes of tremor associated with changes in the vigor of spattering within the Overlook vent. Sulfur dioxide emissions from the summit vent ranged from 4,100 to 8,000 metric tons/day over the past two weeks when measurements were possible during good trade wind conditions.
Data from GPS networks and InSAR (satellite radar) show continued long-term inflation of the summit and upper Southwest Rift Zone magma reservoirs."

The new surface lava flows from the two breakouts north and northeast of Pu'u 'O'o vent on the eastern rift zone remain active. They form broad, branching channels that have been gradually enlarging the two new pahoehoe lava flow fields NW/W and SE of the cone. ... read all

Early in the morning of 24 May (at 06:50 local time), a sudden surge in lava supply caused the main lava tube carrying the lava underground away from Pu'u 'O'o to rupture. This resulted in two so-called surface lava breakouts located about 500 m N and NE from the cone, feeding two new large surface lava flows. ... read all

The activity of the volcano remains essentially unchanged. Rising magma levels under the east rift zone briefly caused an overflow of lava that erupted from a spatter cone within the southern part of the Puʻu ʻŌʻō crater. ... read all

No significant changes in activity have occurred in the ongoing eruption of Kilauea. In recent weeks, lava from Pu'u 'O'o continued to aliment lava tubes feeding the large pahoehoe flow field to the NE. read all
