The June 27th lava flow remains active and continues to widen

The June 27th lava flow remains active in and upslope from Pāhoa. Yesterday, the tip of the flow was stalled about 155 meters (170 yards) from Pāhoa Village Road, which crosses the photo at lower right. A few small toes of pasty lava continue to leak from the sides of the flow just upslope from the front today. A more vigorous flow was burning through forest along the north side of the stalled front just below the Pāhoa cemetery (the burning forest closest to Pāhoa Village Road). This may develop into a new front. Other breakouts even farther upslope were also moving through vegetation and producing smoke plumes.

Left: This is a closer view of the leading part of the flow, looking toward Pāhoa Village Road, which cuts across the top of the photo. The smoke marks where an active breakout is advancing downslope along the north side of the finger which stalled yesterday after crossing through private property. Right: A few small breakouts remain active near the transfer station, seen at lower right. One breakout, active for several days now, is slowly creeping toward the southern edge of the transfer station, and was about 35 m away today. Another breakout started overnight on the south side of the flow opposite from the lobe heading toward the transfer station. This southern breakout destroyed a cow shelter in the adjacent pasture and is the source of the smoke near the upper left side of the photo.

Left: A hole is left behind by a large tree that was surrounded by lava, burned through at its base, and collapsed onto the solidified flow surface a short time before this photo was taken. The end of the tree trunk is glowing, and flames from burning wood are emanating from the hole. This represents an under appreciated hazard of the lava flow field. Large trees that were surrounded by lava can fall long after the leading edge of the flow has passed by. Right: Lava from the lobe that was active in the forest below the Pāhoa cemetery overcomes a fence marking private property late on Friday afternoon.

June 27th lava flow advance rate slows

Minor breakouts of lava ooze from the margin of the June 27th lava flow on the afternoon of Thursday, October 30, 2014. These breakouts are located about 100 meters (110 yards) behind the leading edge of the flow.

Left: Lava near the leading edge of the June 27th flow oozed over a concrete slab and towards a tangerine tree before solidifying Thursday afternoon. Right: The June 27th lava flow came into contact and inflated against an artificial berm on private property on Thursday afternoon. Note that the flow has inflated to a level much higher than that of the berm.

June 27th lava flow advances toward Pāhoa Village Road

The June 27th flow remains active, and is slowly approaching Pāhoa Village Road. This photo was taken just before 10 am, and shows the flow front moving through private property towards a low point on the road. At 11:30 am today, the flow front was 215 m (235 yards) from Pāhoa Village Road.

Left: Another view of the flow front and its proximity to Pāhoa Village Road. Photo was taken just before 10 am. Right: This photo looks downslope from Cemetery Road, and shows the pasture and cemetery that the flow front advanced through several days ago. Much of the cemetery has been covered by lava, but a kipuka has left a portion of the cemetery uncovered for now.

A comparison of a normal photograph with a thermal image of the flow front. The white box shows the extent of the thermal image. The thermal image shows that most of the activity in this region is focused at the leading edge of the flow (white and yellow areas show active surface lava). In addition, a small lobe on the western margin of the flow is active (and partially obscured) in thick forest above the private lot that the front is moving through.

June 27th flow enters Pāhoa

The June 27th lava flow burns vegetation as it approaches a property boundary above Pāhoa early on the morning of Tuesday, October 28, 2014.

Left: Lava pushed through a fence marking a property boundary above Pāhoa early on Tuesday morning. Right: By dawn on Tuesday morning, lava had crossed into two privately owned properties above Pāhoa. Note the inflated flow behind the fence, which is chest-high. We are grateful to the owners of the property for allowing us access and permission to work on their land and post these photos.

June 27th flow approaching residential areas in Pāhoa

The June 27th lava flow remained active, and the flow front was nearing residential areas in the northwest portion of Pāhoa. The flow front was heading towards a low spot on the Pāhoa Village Road, between Apaʻa St. and the post office. This photo was taken at 11:30 am today, when the flow front was 540 meters (0.3 miles) from Pāhoa Village Road.

Left: This annotated photograph shows the notable features around the flow front. The photo was taken at 11:30 am, and also shows the distance the flow front has traveled between Cemetery Rd./Apaʻa St. and Pāhoa Village Rd. Right: A slightly closer view of the flow front. Apaʻa St. is in the lower portion of the photograph, and the transfer station is in the lower right. Pāhoa Village Road is in the upper left portion of the photograph.

A wider view of the flow, showing its proximity to Pāhoa Village Road. Pāhoa Village Road spans the bottom portion of the photograph.

A comparison of a normal photograph with a thermal image. The white box shows the approximate extent of the thermal image. The elevated temperatures (white and yellow areas) around the flow front indicate that significant activity is focused at the front, driving its forward movement. In addition, a slow-moving lobe was active upslope of Cemetery Rd. Farther upslope, scattered breakouts persist in the wider portion of the flow.

Left: Another wide view of the flow front and its position relative to Pāhoa. Right: This Quicktime movie, taken at 11:30am, gives an aerial overview of the flow front and its position relative to Pāhoa. The movie is fairly large in size and may take several minutes to download.

June 27th flow continues to advance toward Pāhoa

Left: As of 10 AM, HST, on October 26, 2014, the June 27th flow front remains active and continues to advance towards the northeast. A portion of the front is still moving through the open field (shown here), while the leading tip of the flow has advanced through the Pāhoa cemetery. Right: An HVO geologist maps the margin of the June 27th lava flow in the open field below Apaʻa Street / Cemetery Road.

An HVO geologist walks across the surface of the flow, which covers the short access road to the cemetery. As is typical for pāhoehoe, the flow has inflated over the past day and was chest high in many places.

Left: A palm tree is surrounded by lava as it advances across the grassy pasture below the Pāhoa cemetery on Sunday afternoon. Right: Incandescent cracks are abundant in the surface of the June 27th lava flow just above the Pāhoa cemetery. Lava is accumulating beneath the flow's upper crust, causing it to inflate.

Late on Sunday afternoon, a barbed wire fence is overrun by lava from the June 27th flow lobe that crossed through the Pāhoa cemetery earlier in the day. To the far left in the distance, a plume of smoke marks the location of the flow lobe that passed southeast of the cemetery and through the pasture.

June 27th flow crosses Apaʻa Street

Left: The June 27th lava flow crossed Apaʻa Street / Cemetery Road at 3:50 AM, HST, Saturday morning, October 25, 2014. In this photo, which was taken at about 9 AM Saturday, the flow is moving from right to left, with burning asphalt visible along it's NW margin. A utility pole, far right, was surrounded by lava but remained standing at the time of the photo. The hope is that the protective insulation and cinder/cement barrier around the pole will prevent it from burning through. Right: At 11 AM Saturday, the June 27th flow was advancing down the grassy driveway that leads to the Pāhoa cemetery. This view is looking upslope towards Apaʻa Street along the cemetery driveway.

Left: The June 27th lava flow advances across the pasture between the Pāhoa cemetery and Apaʻa Street, surrounding a barbed wire fence. Right: A small shed is consumed by lava in the pasture between the Pāhoa cemetery and Apaʻa Street.

A typical portion of the pāhoehoe flow margin near the flow front, just downslope of Cemetery Rd./Apaʻa St. The horizontal incandescent cracks seen in the center and right portions of the photo indicate that the flow was inflating. Pāhoehoe inflation is driven by continued supply of lava beneath the surface crust, which slowly raises the surface.

Left: An HVO geologist takes a GPS waypoint at the flow front. This measurement is done sequentially throughout the day to measure flow advance rates. The flow front was moving through tall grass in an open field downslope of Apaʻa St. today. Right: A section of the flow margin near the flow front, showing a continuous horizontal incandescent crack that indicates ongoing flow inflation. HVO geologist for scale. The flow here was only about a meter thick, but slightly farther upslope where the lava has had more time to inflate the thickness was closer to two meters.

Left: Some of the flow front had the appearance of "slabby" pāhoehoe, which is the type of pāhoehoe in which the surface consists of numerous broken, overturned slabs. Right: One of the rotated surface slabs presses against the fencing that runs along the small road to the cemetery.

June 27th flow front approaches Cemetery Rd./Apaʻa St.

The June 27th flow remains active, and has advanced at an increased rate over the past two days. This afternoon (2 pm), the flow front was pushing ahead as a narrow lobe, and was just 135 m (150 yards) from Cemetery Rd./Apaʻa St. The vent for the June 27th flow is on Puʻu ʻŌʻō (top of photograph), which is nearly 19 km (12 miles) away.

Left: A wider view of the flow front, and its position relative to Pāhoa. This morning the flow front was 1.2 km (0.7 miles) from Pāhoa Village Road, as measured along a straight line. Pāhoa Village Road is at the bottom of the photograph. Right: A closer view of the flow front, which has split into two separate lobes. As of 2 PM, the flow was only 135 m (approximately 150 yards) from Cemetery Rd./Apaʻa St., which spans this photo. HELCO crews can be seen working to protect utility poles along the road.

Left: Another view of the two lobes that make up the flow front. Vehicles for scale. Right: Just upslope of the flow front, the flow can be seen here parallel to the dirt road. The flow in this section was only about 30 m (100 feet) wide.

Left: Another view of the flow front and Cemetery Rd./Apaʻa St., looking east. The flow front is entering an open pasture. Right: HVO geologists can be seen in the pasture mapping the flow front position.

Another view of the leading tip of the flow, as it moves into the open pasture.

A comparison of a normal photograph with a thermal image of the flow front. The white box shows the approximate area of the thermal image. The thermal image shows that high temperatures are concentrated around the leading tip of the flow, which is consistent with lava focused at the front to sustain a higher advance rate.

Left: This Quicktime movie shows a close-up view of the flow front, and its proximity to Cemetery Rd./Apaʻa St. The transfer station is also shown. Right: This Quicktime movie shows a wider view of the flow front, and pans to the right to show the flow's proximity to Pāhoa.

June 27th lava flow continues advancement towards northeast

Left: The June 27th lava flow remains active, and continues to advance towards the northeast along the northern boundary of Kaohe Homesteads subdivision. Over the past day, the leading edge of the flow has moved ahead as a narrow lobe, and covered part of a dirt road. The flow front today was 815 meters (0.5 miles) from Apaʻa St., as measured along a straight line. Right: A wider view of the flow front, showing its proximity to Apaʻa St. and the transfer station. The vent for the June 27th lava flow is on Puʻu ʻŌʻō cone, which can be seen in the upper right portion of the photograph. The residential area in the lower left corner is in the western portion of Pāhoa.

Left: A closer view of the flow front from the air, showing the narrow lobe of lava moving along the dirt road. Kaohe Homesteads is in the left side of the photograph. Puʻu ʻŌʻō can be seen in the upper right. Right: Another view of the flow front, showing the numerous smoke plumes arising from active breakouts burning vegetation at the flow margin. Kaohe Homesteads is in the left side of the photograph.

A comparison of a normal photograph of the flow front with a thermal image. The white box shows the approximate extent of the thermal image. The thermal image shows that active breakouts (white and yellow areas) are focused along the narrow lobe at the leading edge of the flow, but are also scattered for about 2 km (1.2 miles) behind the flow front.

Left: A vertical view of the lava upslope from the flow front covering the dirt road. Right: A view of the flow front from the ground, showing the pāhoehoe lava slowly moving through thick vegetation and creating thick plumes of smoke. Frequent methane explosions were occurring. These result from the cooked vegetation releasing methane, which then ignites. The explosions can range from small puffs to loud cannon-like blasts, and are an additional hazard in the immediate area of the flow margin. More information on methane explosions can be found here: http://hvo.wr.usgs.gov/volcanowatch/archive/2002/02_10_17.html

Left: An HVO geologist marks the coordinates of the flow front with a GPS unit. Right: HVO geologists walk over the surface of the flow to track surface breakouts along a portion of the flow margin, about a kilometer (0.6 miles) upslope of the flow front.

Left: This Quicktime movie provides an aerial overview of the flow front. Right: This Quicktime movie was captured at the flow front, and shows a small channelized portion of the pāhoehoe flow pouring over the dirt road embankment. Gas trapped within the flow is released via occasional small bubble bursts.

Satellite image shows update on flow activity

This satellite image was captured by the Advanced Land Imager instrument onboard NASA's Earth Observing 1 satellite. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures, and show active lava. White areas are clouds.

The image shows that the flow remains active. Most active breakouts are focused near the flow front. These breakouts extend from the leading tip of the flow back to about 2 km (1.2 miles) behind the front. Several small breakouts are also active in the area where lava is moving through ground cracks. The June 27 vent is on Puʻu ʻŌʻō, and Puʻu ʻŌʻō Crater contains several small hot spots (which are caused by several small incandescent holes on the crater floor). The newly cleared portion of Chain of Craters Road is also faintly visible near the coastline.
