The first (#16) opened about 06:45 local time yesterday morning about 1 mile northeast of fissure 15 at the northeast end of the existing vent system, and produced minor lava spattering, and a lava flow that reached about 250 m length until ending activity at about 14:30.
The next one (#17) opened at around 18:00 in the evening just east of fissure 16, about a half mile northeast from the end of Hinalo Road.
According to HVO, "lava from this latest outbreak is actively spattering and degassing but no flow has yet formed. This area was actively steaming earlier in the day."
Earthquake activity, ground deformation, and continuing high emission rates of sulphur dioxide in the area indicate additional outbreaks of lava are likely as this eruption continues. The location of future outbreaks could include areas both uprift (southwest) and downrift (northeast) of the existing fissures, or, existing fissures can be reactivated. Communities downslope of these fissures could be at risk from lava inundation."
"Kīlauea Volcano Summit
Deflationary tilt continues. Based on this and field observations of the past two days, the lava lake level continues to drop. Over the course of the day, rockfalls from the steep enclosing crater walls have generated small ash clouds mixed with white condensed water vapor intermittently throughout the day. These ash clouds have been relatively low concentration and have risen only a few thousand feet above the ground, a few generating very localized ashfall downwind. More explosive activity generating larger ash clouds remains possible and can occur with no warning.
Earthquake activity in the summit remains elevated with several felt events at HVO today. Many of these earthquakes are related to the ongoing subsidence of the summit area and earthquakes beneath the south flank of the volcano." (HVO / USGS)

The summit lava lake inside Halema'uma'u crater continues to drop and the summit continues to deflate. As of yesterday evening, the lava lake's surface was 295 m (970 ft) below the floor of the crater, leaving a deep funnel. Lava is no longer visible on the webcam images. ... [more]

The intermittent lower east rift zone eruption in the Leilani Estates continues. New fissures and areas of ground steaming have appeared, enlarging the affected area both down- (towards NE) and uprift (SW direction), showing that the intrusion of magma continues. ... [more]
