New Map Puts Pahoa Marketplace in Lava Flow Path

USGS Hawaiian Volcano Observatory (HVO) scientists conducted an overflight at midday on Monday, mapping and observing the entire length of the June 27th lava flow field.

The breakouts that began about two weeks ago near the area of ground cracks continued to advance downslope over the past week, creating a new lobe on the June 27th lava flow. This lobe is a short distance west of the earlier portion of the June 27th flow that reached Pāhoa. The new lobe advanced about 2.8 km (1.7 miles) over the past week, which is equivalent to about 400 meters per day (0.25 miles per day). A narrow lava channel was active this morning at the leading tip of the new lobe. The leading tip of this active lobe was 4.6 km (2.9 miles) upslope from the intersection of Highway 130 and Pāhoa Village Road (the intersection by Pahoa Marketplace).

The breakouts that began about two weeks ago near the area of ground cracks continued to advance downslope over the past week, creating a new lobe on the June 27th lava flow. This lobe is a short distance west of the earlier portion of the June 27th flow that reached Pāhoa. The new lobe advanced about 2.8 km (1.7 miles) over the past week, which is equivalent to about 400 meters per day (0.25 miles per day). A narrow lava channel was active this morning at the leading tip of the new lobe. The leading tip of this active lobe was 4.6 km (2.9 miles) upslope from the intersection of Highway 130 and Pāhoa Village Road (the intersection by Pahoa Marketplace).

Since the last overflight on November 24, a narrow finger has broken away from the west edge of the flow field and moved to the north by about 2.8 km (1.7 mi), which is an average advance rate of 400 meters/day (440 yards/day). The finger branches off at a point downslope of the crack system where the older flow makes a bend from the north to the northeast. Along its length, the width of the active finger varies from 30 meters (33 yards) to 180 meters (200 yards). The total length of the flow, between Puʻu ʻŌʻō and the front of the new finger, is 18.3 km (11.4 mi) as measured along the flow axis.

A closer look at the narrow lava channel near the leading tip of the active lobe. The channel consists of both open sections as well as sections that are crusted over.

The new finger is following a different steepest-descent path than the previously active flow lobe. The new forecast path takes the flow towards the intersection of Pāhoa Village Road and Highway 130, in the vicinity of the Pahoa Marketplace. The flow is currently about 4.6 km (2.9 miles) upslope of the intersection as measured along a straight line. The flow is approaching an area of gentler topography, however, where two steepest-descent paths nearly converge. The ultimate flow path is therefore difficult to forecast while the activity remains upslope of this point.

This map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of the June 27th lava flow. The area of the flow on November 24, 2014, at 12:00 PM is shown in pink, while widening and advancement of the flow as mapped on December 1 at 11:30 AM is shown in red. Most surface flow activity is focused into a narrow finger that branches off the west edge of the flow field north of the East Rift Zone crack system. The front of this finger (19.475836, -154.986834 Decimal Degrees) was 4.6 km (2.9 mi) upslope from the intersection of Highway 130 and Pāhoa Village Road at the Pahoa Marketplace. The dotted blue lines show the pertinent steepest-descent paths, calculated from a 1983 digital elevation model (DEM; for calculation details, see http://pubs.usgs.gov/of/2007/1264/), that the flow is projected to follow. Note that about 1 km (0.6 mi) downslope from the tip of the active flow two different steepest-descent paths come very close together. This is a location where the ground becomes very flat, and the flow could end up following either (or both) of these paths. Steepest-descent path analysis is based on the assumption that the DEM perfectly represents the earth's surface. DEMs, however, are not perfect, so the dotted blue line can be used to infer only an approximate flow path.  (Click to Enlarge)

During the overflight, HVO scientists were also able to measure the cross-sectional area of the lava stream within the tube near Puʻu ʻŌʻō. Their result of 2.0 square meters (2.4 square yards) is a 25% reduction in area compared to last week. A smaller lava-stream cross section is consistent with less lava flowing through the tube due to the current summit deflation, which has been ongoing since Saturday morning.

Based on the gentler topography that the flow is approaching and the decrease in cross-sectional area of the lava stream within the tube, it is likely that the advance rate of the narrow finger will slow in the coming days.

The normal photograph is partially obscured by smoke from vegetation burning, but the thermal image can "see" through the smoke to show the nature of the channel in detail. Some sections of the channel are completely covered by crust (forming a lava tube), while other sections were open with a smoothly flowing surface.

Some sections of the channel are completely covered by crust (forming a lava tube), while other sections were open with a smoothly flowing surface.

In addition to the narrow finger, weak activity is also present in three areas upslope: 1) surface lava was active where the new finger branches off from the existing flow field; 2) minor surface flows were extending the flow margin to the east at the eastern edge of the crack system; and 3) about 3.5 km (2.2 mi) downslope from Puʻu ʻŌʻō, small amounts of surface lava marked the continued activity of the breakout that started near the Kahaualeʻa cone about two weeks ago. Observations of the stalled flow that extends from the crack system into Pāhoa Village indicate that the lava tube is not being reoccupied, and that this lobe of the flow is effectively inactive.

Lava Breakouts Remain Active Around Ground Crack System and Well Site

The farthest downslope breakouts today are still situated around the ground crack system, near the abandoned well site. The front of these breakouts was about 500 m (0.3 miles) northeast of the well site, and about 1.9 km (1.2 miles) west of Kaohe Homesteads.

These breakouts were covering the existing flow and burning forest on its margins.  (Click to enlarge)

Inflation along the lava tube has created a long ridge with a deep, semi-continuous crack along the ridge centerline (right side of image). The peak of the ridge, by rough estimate, is about 4 meters (13 feet) above the original ground surface. This photo looked northeast along the trend of the tube, just south of the cemetery. The short section of uncovered road is the cemetery access road.

Earlier in the week lava reached the outer fence of the transfer station, sending several small cascades through the fence and down the embankment. Burning of the asphalt continued for several days. Now that burning has ceased at the transfer station, a closer look at these features was possible. Note that the lava which stalled at the fence line subsequently inflated to a height slightly greater than that of the fence.

Civil Defense Update – House Was Ignited By Lava Flow

This is an eruption and lava flow Information Update for Monday November 10th at 6:30PM

The current assessment shows that the flow front remains stalled with very little activity and has not advanced. The upslope breakout in the area of Apa’a Street near the cemetery entered a private property yesterday morning and the residential structure or house was ignited by the advancing flow at approximately 11:55 this morning.

Currently, three active breakouts are being monitored in the areas of the cemetery below Apaʻa Street, in the area west or above the transfer station, and upslope approximately .4 miles from Apaʻa Street. All three breakouts are active and advancing in a northeast direction. These breakouts do not pose an immediate threat to area residents and will be monitored.

Smoke conditions are currently moderate to heavy with light trade winds blowing the smoke in a south southwest direction towards the Leilani and lower Puna areas. Smoke conditions may increase in some areas and residents down wind that may be sensitive or have respiratory problems are advised to take necessary precautions and to remain indoors.

The evacuation advisory for those residents down slope of the flow will continue and residents will be kept informed of the flow status and advancement.

The Pahoa Village Road between Apa’a Street and the Post Office Road will remain closed and limited to area residents only. In addition, Civil Defense and public safety personnel will be operating in the area round the clock to maintain close observations of flow activity. Additional updates will be broadcasted as conditions change.

We would like to thank everyone for your patience and understanding and your cooperation and assistance is greatly appreciated. Thank you for listening and have a safe day. This is your Hawaii County Civil Defense.

HELCO Response to Utility Pole on Fire in Lava Flow Path

No power interruptions due to the lava flow have been reported and utility poles along Apa’a Street currently remain in place, Hawaii Electric Light Company reports. However, it does appear that one of the poles is beginning to show the impacts of the lava’s heat.

HELCO Pole

“This morning, our technical experts found the pole that was surrounded by lava had sunk about ten feet and either steam or smoke was coming through the cinder piled around the pole. We suspect the pole is burning slowly at the ground level. We cooled the pole and protective barrier with water and will continue to monitor the condition of the pole. At this time, the pole remains standing and it does not appear to have sunk further,” said spokesperson Rhea Lee. “As a precautionary measure, we took the transmission line out of service while we evaluated the situation and cooled the pole. We put this line back in service this afternoon. However, we were able to keep power on for all customers through an alternative transmission line.”

Hawaii Electric Light is continuing with other contingency plans including:

  • Relocating a portion of its primary distribution line to the opposite side of Pahoa Village Road onto two taller poles installed under a joint pole agreement with Hawaiian Telcom. The taller poles were spaced farther apart than normal and allowed Hawaiian Telcom to raise their cables higher on the pole. Hawaii Electric Light was then able to cut the tops of the poles located on the opposite side of the road to reduce the height of the poles in the event lava causes them to fall, thereby minimizing the chance the poles would cause damage to the pole line across the street. The shorter poles contain a distribution line serving customers in the immediate area. Hawaii Electric Light will keep the power on for customers in this section of Pahoa Village Road for as long as it is safe to do so.
  • Crews are extending the distribution line on Government Beach Road between Hawaiian Paradise Park and Hawaiian Beaches to provide power to Hawaiian Beaches should existing lines located closer to Highway 130 become inoperable.
  • Hawaii Electric Light has relocated a large diesel generator to Puna and will be moving a second large diesel generator to the same location. These units will be able to provide power for the lower portion of Puna if this section is cut off from the rest of the island grid.

HELCO Attempts to Protect Power Poles From Lava Flow

Hawaii Electric Light continues to work closely with Hawaii County Civil Defense and other agencies to monitor and evaluate the lava flow and has put into action the plans that are appropriate for this stage, including:

  • Pole protection measures were installed on four poles along Apaa Street. The poles were partially encased with heat resistant and dispersive material to protect them from the heat generated by the lava.
  • A large diesel generator was relocated to the Kapoho area to provide an alternate source of generation should the flow isolate the area from the island-wide power grid.
  • The distribution line extension construction continues on Government Beach Road as an alternate means to provide power to Hawaiian Beaches should the existing power distribution lines become inoperable.

HELCO workers are experimenting on securing the poles on Cemetery Road. 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. (Click to enlarge)

“The safety of our community and employees is our top priority,” said spokesperson Kristen Okinaka. “We’re working closely with Hawaii County Civil Defense and have taken the necessary steps to protect our facilities.”

Hawaii Electric Light advises customers who are planning to move and would like to discontinue or transfer their electric service to call (808) 969-6999. In the event evacuation is necessary before electric service has been removed, the company recommends customers:

  • Shut off electricity at the main breaker or switch;
  • Unplug or turn off electric equipment and appliances.

As there are new developments, updates will be provided to the media and public and also posted on Hawaii Electric Light’s website (www.hawaiielectriclight.com), Twitter (@HIElectricLight), and Facebook (www.facebook.com/HawaiianElectric) accounts.

Lava Flow Enters Kaohe Homesteads

June 27th flow enters northwest portion of Kaohe Homesteads

The June 27th lava flow remains active and continues advancing towards the northeast. Recently, the flow front entered the Kaohe Homesteads subdivision, and is currently within the vacant, forested northwest portion of the subdivision. The flow front was 3.3 km (2.1 miles) upslope from Apaʻa Road and 4.3 km (2.7 miles) from Pāhoa Village Road.

HVO geologists conduct a VLF (very-low frequency) survey to measure the rate of lava flowing through the lava tube on the June 27th lava flow.
An HVO geologist conducts a very-low frequency (VLF) survey of the lava tube to measure the rate of lava flowing through the tube. The measurement consists of two steps. First, a transect of VLF measurements across the roof of the tube is used to measure the cross-sectional area of lava flowing through the tube. Second, a radar gun is used to measure the speed that lava is flowing at that location. An open skylight is required for this speed measurement. By multiplying the cross-sectional area with the velocity, the volume rate of lava flowing through the tube can be estimated. Today’s measurement showed a flow rate of 5.8 cubic meters per second (roughly 1500 gallons per second). Tracking the lava supply rate like this can be helpful for anticipating fluctuations in activity at the flow front.

Another Lava Flow Update This Evening From USGS – Video of Flow

Between September 6 and 10, the June 27th flow advanced north then northeastward at an average rate of 400 m/d (0.25 mi/d).

Click to view movie

This Quicktime movie provides an overview of activity near the front of the June 27th lava flow, and shows the position of the flow front relative to Kaohe Homesteads and Pahoa.

In this way, the flow had advanced approximately 14.5 km (9.0 miles straight-line distance) from the vent, or to within 0.6 km (0.4 miles) of the eastern boundary of the Wao Kele o Puna Forest Reserve, by the afternoon of September 10. At the average rate of advancement of 400 m/day (0.25 mi/day) since September 6, we project that lava could flow from its current location to the northwest edge of Kaohe Homesteads in 1.5 days and to the Pāhoa Village road (government road) in Pāhoa within 14-16 days if lava is not further confined within the cracks and down-dropped blocks within the East Rift Zone of Kīlauea volcano. These estimates will be continually refined as we track this lava flow.

Kaohe Homesteads is located between the Wao Kele o Puna Forest Reserve and the town of Pāhoa in the Puna District of the County of Hawai`i.

Recent Observations: Lava flow turned to the northeast and is advancing at a rate of 400 m/day (0.25 mi/day).

Hazard Analysis: Lava Flow from Pu‘u ‘Ō‘ō vent could reach the northwest edge of Kaohe Homesteads in 1.5 days and the government road in Pāhoa within 14-16 days.

Remarks: The Pu‘u ‘Ō‘ō vent in the East Rift Zone of Kīlauea Volcano began erupting on January 3, 1983, and has continued erupting for more than 31 years, with the majority of lava flows advancing to the south. Over the past two years, lava flows have issued from the vent toward the northeast. The June 27th flow is the most recent of these flows and the first to threaten a residential area since 2010-2011. On June 27, 2014, new vents opened on the northeast flank of the Pu‘u ‘O‘o cone that fed a narrow lava flow to the east-northeast. On August 18, the flow entered a ground crack, traveled underground for several days, then resurfaced to form a small lava pad. The sequence was repeated three more times over the following days with lava entering and filling other cracks before reappearing at the surface, in two of the cases farther downslope. Lava emerged from the last crack on September 6 and moved as a surface flow to the northeast.

Lava Flow Update – Flow Advances About 300 Yards in About 6 Hours

The June 27th lava flow remains active. An HVO flight early in the afternoon yesterday found that the flow had advanced ~280 m (~300 yards) north since a Civil Defense flight just after sunrise that morning (a span of ~6 hours), and the flow front had reached a large crack marked on the topographic base map (but not visible from the air). There was no evidence that the flow was entering this crack, if it exists.

A Civil Defense overflight this morning found that the flow front had advanced an additional 370 meters (400 yards) since yesterday afternoon. This puts the tip of the flow at 14.0 km (8.7 miles) from the vent, measured in a straight line, and 1.1 km (0.7 miles) from the Forest Reserve boundary.

The actual length of the flow, measured along the lava tube axis (so that bends in the flow are considered) is 16.0 km (9.9 miles). The flow front is still in thick forest, creating smoke plumes as it engulfs trees and other vegetation, but fires are not spreading away from the flow.

Small breakouts also remain active closer to Puʻu ʻŌʻō, roughly midway along the length of the June 27th flow. None of these breakouts have been very vigorous recently, but are also producing smoke plumes a they creep into the adjacent forest.

Lava Could Hit Government Road in Pahoa in 16-18 Days

On June 27, 2014, new vents opened on the northeast flank of the Pu‘u ‘O‘o cone that fed a narrow lava flow to the east-northeast. On August 18, the flow entered a ground crack, traveled underground for several days, then resurfaced to form a small lava pad.

close up lava map

The sequence was repeated three more times over the following days with lava entering and filling other cracks before reappearing at the surface, in two of the cases farther downslope. Lava emerged from the last crack on September 6 and moved as a surface flow to the north. Between September 6 and 8, the flow advanced northward at a rate of 400 m/d (1,300 ft/d).

In this way, the flow had advanced approximately 13.7 km (8.5 miles straight-line distance) from the vent, or to within 1.2 km (0.7 miles) of the eastern boundary of the Wao Kele o Puna Forest Reserve, by the afternoon of September 8. At the average rate of advancement of 400 m/day (1,300 ft/day) since September 6, we project that lava could flow from its current location either through the north part of Kaohe Homesteads, or to the north of Kaohe Homesteads, and reach the government road in Pāhoa within 16-18 days if lava is not further confined within the cracks and down-dropped blocks within the East Rift Zone of Kīlauea volcano. These estimates will be continually refined as we track this lava flow.

Kaohe Homesteads is located between the Wao Kele o Puna Forest Reserve and the town of Pāhoa in the Puna District of the County of Hawai`i.

The farthest lava this afternoon was 13.2 km (8.2 miles) from the vent on Puʻu ʻŌʻō, and 1.3 km (0.8 miles) from the eastern boundary of the Wao Kele o Puna forest reserve. This forest reserve boundary is at the western boundary of Kaohe Homesteads subdivision, a portion of which is visible at the bottom of the photograph.

This view looks east at the far end of the June 27th lava flow. In the center of the photograph is an isolated pad of lava which came out of ground crack last week. Further movement of lava within ground cracks has enabled the flow front to advance farther east, with lava issuing from a ground crack in the upper left portion of the photograph, where plumes of smoke mark the location of lava burning forest.

This Quicktime movie shows activity at the front of the June 27th lava flow. The flow front continues to advance eastward, with lava issuing out of a ground crack and spreading through dense forest, creating thick plumes of smoke. The farthest lava this afternoon was 1.3 km (0.8 miles) from the eastern boundary of the Wao Kele o Puna forest reserve.

The area of the flow as mapped on August 27 is shown in pink, while widening and advancement of the flow as of August 28 is shown in red. All older lava flows (1983–2014) are shown in gray. The thin yellow line marks a portion of the lava tube feeding the flow.

The only place where lava significantly widened the margin was at the most distant surface breakout, which was 8.6 km (5.3 miles) from the vent. The brown line at the far end of the flow marks the ground crack that channeled lava to the east, where it later emerged to form a new pad of lava.

Yesterday, there was no surface activity there and no indication that lava was continuing to advance within ground cracks. This morning, however, steam was rising above a crack extending east beyond the end of the lava pad, suggesting that lava was once again advancing within a crack below ground.

The most distant steaming area was 11.9 km (7.4 miles) from the vent and 2.6 km (1.6 miles) from east boundary of the Wao Kele o Puna Forest Reserve.
