Hawai’i Volcanoes National Park Volcano Activity Information & Updates
Sunday | November 23 | 2014
The USGS Hawaiian Volcano Observatory and Hawai’i Volcanoes National Park Service reportsthatKīlauea Volcano continues it’s active eruption in two locations:Halema’uma’u crater in Kīlauea’s summit area, and Pu’u ‘Ō’ō vent within Hawai’i Volcanoes National Park’s east rift. Both eruption sites are creating elevated sulphur dioxide gas emissions. At the middle East Rift Zone, the June 27th flow’s foremost tip remains inactive, with no indication lava is still moving through the frontal part of the tube system. However, the June 27th flow is exhibiting two areas of breakouts focused within the upper part of its flow field. One, about 2.5 miles, or 4 km from the base of Puʻu ʻŌʻō, and the second, around the flow’s ground crack system. The foremost breakout has advanced approximately 0.2 miles, or 370 meters along the northwest margin over the past 24-hours. This furthest activity from Puʻu ʻŌʻō indicates to scientists that lava remains, and is potentially reoccupying the lava tube system.
Halema’uma’u Crater The simplest way to view Kīlauea Volcano’s eruptive activity is from Kīlauea’s caldera rim area, with the Jaggar Museum as the most ideal location. But, you will not see active lava flow here. What you will see is:
During daylight hours a towering billowing ash and volcanic gas plume emitting from Halema’uma’u pit crater. A signal to the fact that there’s really a lot going on under the surface! In the past 24 hours seismic tremor remained low and varied beneath Kīlauea’s summit.
At dusk and nighttime hours it gets a bit more exciting. As of Sunday, November 23, 2014 the molten lava lake that churns energetically within Halema’uma’u crater remains stable, exhibiting almost daily inflations, or deflations. The lake itself continues to fluctuate, and is currently reported to range from approximately 160 feet (49 m) to 200 feet (61 m) below the surface. Still considered relatively high, the levels of the lava lake make for impressively striking effects, as the crater’s plume glows with reds, pinks, and yellows and appears to be spewing fire.
Pu’u ‘Ō’ō Vent and Cone All the drama is more difficult to observe; lava continues to flow in the Park’s east rift zone.
It is presently considered illegal and highly dangerous to attempt hiking to view Pu’u ‘Ō’ō’s leading edge, current ground crack and surface flow activity. The length of the flow field is mostly within the closed-access areas of Hawaiʻi Volcanoes National Park and adjacent State land managed by the Department of Land and Natural Resources, or the Office of Hawaiian Affairs. These areas include the Kahaualeʻa Natural Area Reserve (NAR), and the Wao Kele o Puna Forest Reserve (DLNR, OHA). Entry into closed lands is a violation of Hawai’i law and is subject of penalty up to $5,000. Additionally, the Governor’s recent emergency proclamation enhances the penalties for any offense committed during this time.
As of today, the June 27th flow’s current front is occurring within a restricted access area, immediately west of the Big Island town Pāhoa. For safety purposes of all those concerned, this area is being observed and monitored 24-hours a day by Hawaiʻi Civil Defense and public safety personnel. Access to the private Kaohe Homesteads subdivision is restricted to area residents only. Pahoa Village Road between Apa’a Street and the Post Office Road is closed; access is limited to area residents only. Hawaiʻi County Civil Defense advises that motorists should use caution and slow down on Highway 130 near the Post Office Road intersection. Residents of the restricted area should not bring unauthorized persons into the restricted area.
Within the Pu’u ‘Ō’ō crater, visible glow and incandescence is mostly present from multiple sources including hot openings an out gassings within the crater’s numerous pits, including north, northeast, south, and southeast areas of the crater floor. Frequently, these vents can overflow, creating surface lava ponds.
As of Sunday, November 23, 2014, the USGS reports the June 27th flow’s leading edge continues to remain inactive. No significant breakouts have observed in the downslope portion of the June 27th lava flow, near Kaohe Homesteads and town of Pāhoa. Essentially all active surface flows are now limited to the upslope portion of the June 27th flow, located in the area from the base of Puʻu ʻŌʻō, to within the area’s ground crack system.
HVO observations over the past 24-hours include: A cloud-free satellite image collected on Saturday, November 22, 2014 showed that active breakouts are focused in two areas of the June 27th lava flow. In the upper part of the flow field, a breakout was active about 2.5 miles, or 4 km northeast of Puʻu ʻŌʻō. The second area of breakouts was active around the ground crack system. The front of these breakouts has advanced roughly 0.2 miles, or 370 meters north over the past 24-hours; moving along the western margin of the existing June 27th flow. The front of the furthest breakout was approximately 3.6 miles, or 5.8 km upslope, or to the west-southwest of Apaʻa Street (Cemetery Road), as measured along a straight line.
On November 23, 2014, the June 27th flow front remains recorded at approximately 170 yards, or 155 meters in a straight-line distance from Pāhoa Village Road, and about 815 yards, or 745 meters in a straight-line distance from Highway 130. Its width remains at approximately 60 yards, or 55 meters wide. HVO scientists advise if the June 27th flow were to resume advancement activity, they expect the June 27th flow to cross Pāhoa Village Road between Apaʻa St and Post Office Road.
The USGS reports minor smoldering of vegetation near the flow margins, which is creating modest smokey conditions. With trade winds from the northeast, the light smoke is moving in a south-southwest direction.
The June 27th flow is the first to threaten a residential area since 2010-2011. Based on the current flow location, direction and advancement, residents in the flow path have been placed on an evacuation advisory and notified of possible need for evacuation immediately. The evacuation advisory for those residents down slope of the flow will continue and residents will be kept informed of the June 27th flow status and its advancement.
The USGS reminds that daily fluctuations in flow advancement rate are common for pahoehoe lava flows - the smooth, billowy, rolling, or ropy surface created by the movement of very fluid lava under a solidifying surface crust. They continue to advise the advancement rate of the June 27th flow could rise or fall again in the coming days due to the variable nature of the eruption.
Pu’u ‘Ō’ō’s dramatic activity can only safely be viewed from above, but at times can be obscured, due to dense ash, gas emissions, steam and smoke plumes. (See the photos below, and to your right for and idea of what you may see.)
Within the “Peace Day” flow to the southeast, as of today, there is no clear evidence of any lava flow activity above or below the pali, or on the coastal plain; and all lava ocean entry has ceased.
Currently, Pu’u ‘Ō’ō’s east rift activity can not be viewed from the County of Hawaii’s Kalapana Viewing Area.

Photo Above: Seen from above on Sunday, October 26, 2014, the June 27th flow crossed Apaʻa Street (Cemetery Road) and was moving at rates up to 11 to 16 yards, or 10 and 15 meters per hour. The fastest advancing finger of lava is now only about 620 yards, or 570 meters from Pāhoa Village Road.
Photo Above: On Saturday, October 25, 2014, the June 27th lava flow crossed Apaʻa Street (Cemetery Road) at 3:50 a.m., HST. In this photo, taken at about 9 a.m., the flow is moving from right to left, with burning asphalt visible along its northwest margin. A utility pole, far right, was surrounded by lava but remained standing at the time of the photo.
Photo Above: Taken on Friday, October 24, 2014, the June 27th flow remains active, and has advanced at an increased rate over the past two days. At this time, the flow front was pushing ahead as a narrow lobe, and was just 150 yards, or 135 m from Apaʻa Street (Cemetery Road). The vent for the June 27th flow is on Puʻu ʻŌʻō (top of photograph), which is nearly 12 miles, or 19 km away.
Photo Above: Taken on Wednesday, October 15, 2014 the June 27th lava flow remained active, but at a much reduced advancement rate of only about 55 yards, or 50 meters in two days. Still too close for comfort, the flow front was 0.7 miles, or 1.1 km from Apaʻa Street, as measured along a straight line.
Photo Above:As seen on Monday, October 6, 2014 the June 27th lava flow continued advancing towards the northeast. Moving in a narrow lobe through thick forest, its leading front triggered a brush fire active north of the flow. At this time, the flow was 1.1 miles, or 1.7 km upslope of Apaʻa St., and 1.7 miles, or 2.7 km from Pāhoa Village Road.
Photo Above: Getting Closer. Taken on Friday, October 10, 2014 the June 27th lava flow continues advancing towards the northeast. Though only about 600 feet, or 185 meters wide, the front is now only around 0.8 miles, or 1.3 km upslope from Apaʻa Street, and 1.5 miles, or 2.4 km from Pāhoa Village Road.

Photo Above: Pictured on September 17, 2014, Kīlauea Volcano’s summit eruption continues, with its active lava lake located inside Halemaʻumaʻu Crater. At the time of this photo, the lake was roughly 170 feet or 53 meters below the floor of the crater itself. With an average temperature of around 2,200 degrees fahrenheit, or 1,200 degrees celsius, the Kīlauea’s summit lava lake is one hot spot!Just how big is Hale’ma’uma’u’s lava lake? The lake is about 720 feet (220 m) long and 525 feet (160 m) wide – the area of about 21 Olympic-sized pools!

Map Above: In this map, the USGS uses satellite imagery to depict the area around the front of the June 27th lava flow. The area of the flow on November 12 and 13, 2014 is shown in pink, while widening and advancement of the flow as mapped on November 14, 2014 at 1:40 p.m. HST is shown in red. The June 27th flow has not advanced since Thursday, October 30, 2014. At the time of this mapping, although the flow front remained stationary, there were active breakouts on the north side of the flow field 0.4 miles, or 700 meters upslope from Pāhoa Village Road. Surface activity was also continuing elsewhere on the flow with surface breakouts ranging from about 250 yards, or 230 meters to 1.7 miles, or 2.7 kilometers to the northwest of Apaʻa Street, along the flow’s north margin. On the south margin breakouts ranged from 250 yards, or 230 meters to 0.75 miles, or 1.2 kilometers upslope of Apaʻa Street. The tip of the flow remains approximately 170 yards, or 155 meters from Pāhoa Village Road.
The dotted blue lines indicate the steepest-descent paths in the area, These are used by USGS HVO scientists to infer and predict approximate flow paths.

Map Above: The area of the flow on November 14, 2014 is shown in pink, while widening and advancement of the flow as mapped on November 17, 2014 is shown in red. At the time of this mapping, the leading edge of the June 27th flow showed no signs of advancement. Only one hot spot, identified by infrared camera, was noted along the front part of the flow from the East Rift Zone cracks west of Kaohe Homesteads to the stalled flow tip near Pāhoa Village Road. HVO scientist hypothesize that the lava tube feeding this part of the flow field may have been abandoned following the onset of a large breakout from the tube near Puʻu Kahaualeʻa, just downslope from Puʻu ʻŌʻō. However, there were a significant amount of breakouts between Puʻu Kahaualeʻa and the East Rift Zone crack system, the larger of which are noted on the map. This downslope progression of breakouts along the lava tube, suggests a gradual refilling of the tube from Puʻu ʻŌʻō up to around the middle of the crack system -- about 7 miles, or 11 km in a straight line distance downslope of Pu`u `Ō`ō.

Photo Above: Taken on Thursday, November 20, 2014, the farthest breakouts were situated around the ground crack system about 1.2 miles, or 1.9 km west of the Kaohe Homesteads community. Covering the existing flow, the activity triggered brush fires and frequent methane explosions.
Photo Above: Taken on Sunday, November 16, 2014, during the prior week lava had reached the outer fence of the area’s transfer station facility, sending several small cascades through the fence and down the embankment. Seen at the top of the photo, the stalled lava continued to inflate to a height higher than the fence.
Photo Above: Taken on Wednesday, October 29, 2014, the June 27th flow front was active, creeping slowly through private property. The flow’s leading edge, at the time of this photo was about 235 yards, or 215 meters from Pāhoa Village Road.
Photo Above: Seen Thursday, October 30, 2014, a breakout of characteristically ropey pāhoehoe lava along the June 27th flow’s frontal margin. Just upslope of Apaʻa Street, it burns vegetation near the Pāhoa transfer station facility.
Photo Above: On Monday, October 27, 2014 the June 27th lava flow front can be seen nearing residential areas in the northwest portion of the town of Pāhoa. Taken at 11:30 a.m., at that time the flow front was about 0.3 miles, or 540 meters from Pāhoa Village Road.
Photo Above: Taken on Sunday, October 26, 2014, the June 27th flow front continues to advance towards the northeast. As lava moves through an open field below Apaʻa Street (Cemetery Road) an HVO geologist maps its margin.

Photo Above: Taken on Saturday, October 25, 2014, approximately 2,000 degrees fahrenheit, or 3,632 degrees celsius lava is seen burning Apaʻa Street (Cemetery Road) as it rolls right along.
Photo Above: Seen on Wednesday, October 15, 2014, Puʻu ʻŌʻō Crater obscured by thick fume. In the lower portion of the photograph, a trail of fume sources marks the path of the June 27th lava tube. The broad circular feature in the left portion of the photograph is a perched lava pond that was active in July of this year.
Photo Above:Taken on Wednesday, September 24 2014 the June 27th flow’s front ceased advancement and remains relatively inactive. Smaller areas of activity have been observed scattered behind the flow front, with one breakout advancing very slowly northeast from the flow’s north edge. The burn scar in the foreground was caused by a brush fire triggered by the lava flow over the past weekend. It covers much of the lower portion of this photograph.

Photo Above: Taken on September 19, 2014, night skies afire from the June 27th flow. Still a distant 2 miles, or 3.2 km from Pāhoa town, Pele’s wrath warns of impending doom.
Photo Above: Taken on Friday, September 19, the June 27th flow remains active and heading north-northeast, moving through Kaohe Homesteads neighborhood. For several weeks the flow had been moving through thick forest, but as of Friday, the flow front reached the forest boundary, moving on to open ground. The flow front at the time of this photo was 2.4 km (1.5 miles) upslope of Apaʻa St.
Photo Above: Taken on August 28, 2014, Puʻu ʻŌʻō’s upper northeast flank and the active lava flow vent that began June 27. The vent area is now covered by lava, but the lava tube that carries lava to the flow front is clearly visible by the line of blue-colored fume. In the lower right, two skylights can be seen.
Photo Above: Seen on September 1, 2014 looking westward back toward Puʻu ʻŌʻō in the distance, surface flows at the front of the June 27th flow continue slowly moving through thick forest creating scattered brush fires and near its leading edge, a swiftly moving stream of lava continues pouring into a deep ground crack.
Photo Above: Taken on September 8, 2014, closer to Puʻu ʻŌʻō several small lava flow breakouts, producing burning foliage along the middle part of the June 27th flow remain. The current lava flow front can be seen in the far upper left.
