Puna Lava Flow Reaches Fire Break

Breakouts persist upslope of stalled flow front; new breakout at Puʻu ʻŌʻō

22315pic1The leading tip of the June 27th lava flow remains stalled, but breakouts persist upslope of the stalled tip. Today, one of these breakouts (marked by the arrow) had advanced a short distance towards the north, reaching one of the fire break roads.

This comparison of a normal photograph and a thermal image shows the position of active breakouts relative to the inactive flow tip.

This large-scale map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of Kīlauea’s active East Rift Zone lava flow. The area of the flow on January 13 is shown in pink, while widening and advancement of the flow as determined from satellite imagery on January 17 is shown in red. The most distal portion of the flow on January 17 was approximately 700 meters (0.4 miles) from Highway 130. Overall the activity is sluggish and comprised of scattered breakouts and oozing pāhoehoe toes.

The blue lines show steepest-descent paths calculated from a 1983 digital elevation model (DEM; for calculation details, see http://pubs.usgs.gov/of/2007/1264/). 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 blue lines on this map can be used to infer only approximate flow paths.

Brush Fire Caused By Lava Flow Being Monitored

A brush fire caused by the Puna lava flow was reported this afternoon near the firewall.

Lava Flow Prescription Medicine Delivery Plan Implemented

In response to the current June 27th Lava Flow projections that expect the lava to reach Highway 130 sometime this month, Bay Clinic and Walgreens Pharmacy have put a delivery service plan in-place that will ensure continued access to prescription medication for the residents of lower Puna. The pharmaceutical delivery service will be launched on Monday, December 29, 2014 out of Bay Clinic’s Pahoa Family Health Center located at 15-2866 Pahoa Village Road.

lava medsWalgreens Pharmacy personnel will dispense prescription medications Monday through Friday out of the Pahoa Family Health Center from 3PM to 6PM. Same day prescription delivery must be ordered by 1PM that day; any prescriptions ordered after 1PM will be delivered the following workday. There will be no delivery services at the Pahoa Family Health Center on Saturday, Sunday, or holidays. Walgreens will call patients to arrange delivery and pick-up of prescriptions. Due to state pharmacy policy, CII-CV prescriptions will be required to be picked-up from the Walgreens store location.

“This delivery service will continue as long as Railroad Avenue remains unaffected by the lava flow,” said Harold Wallace, Bay Clinic CEO. “We are working on other alternative delivery options should Railroad close due to the lava flow.”

Lava Flow Stalls – New Breakouts Near Geothermal Well Pad

USGS Hawaiian Volcano Observatory (HVO) scientists conducted a helicopter overflight of the June 27th lava flow this afternoon and mapped its leading edge. At the time of the flight, the tip of the flow was stalled about 0.7 km (0.4 miles) from the Pahoa Marketplace, measured in a straight line, but lava was active in several places immediately behind the front.

A small, but fairly vigorous, breakout was active this afternoon about 1 km (0.6 miles) behind the tip of the flow. (click to enlarge)

A small, but fairly vigorous, breakout was active this afternoon about 1 km (0.6 miles) behind the tip of the flow. (click to enlarge)

One or more of these other active lobes could overtake the stalled front in the coming hours to days, or the stalled front could reactivate. Numerous breakouts were also active along the flow in an area extending from 1 to 3 km (0.6 to 2 miles) upslope from the front of the flow, in the ground crack area near the True/Mid-Pacific well pad, and about 3 km (2 miles) downslope from Puʻu ʻŌʻō.

Highway 130 to be Repaired After Lava Crosses – No Guarantee on Fix

With the lava less then 1 mile from crossing Highway 130 here in Pahoa, Senator Russell Ruderman posted the following on Facebook this morning:

Highway 130 repairs!
Big news regarding the highway and lava. The State DOT is planning to ‘repair’ the highway within a week or two if lava crosses highway. This will involve layers of cinder and a gravel roadbed, and if needed, the truck-bed platform that Bryson Kuwohara has proposed. This is wonderful news, meaning we can expect some normalcy soon after if lava breaches the highway. While there is no guarantee, I have a lot of confidence that the state DOT is taking its responsibility to keep Puna accesible seriously, and that their engineers are looking kindly on this plan.

Lava Tree State Park to Reopen Monday

The Department of Land and Natural Resources (DLNR) will reopen portions of Lava Tree State Monument on a limited basis beginning Monday December 8, 2014. The public will be able to visit most of the viewable lava tree molds, the main pavilion and the informational kiosk. The parking lot, comfort station and front portion of the loop trail will also be available for public use.

Lava Tree State Park

The park has been closed due to numerous albizia trees blown down during Tropical Storm Ana in August this year, which park crews have been working to address.

Lava Tree State Park

The back portion of the park will remain closed until further notice. “We ask that the public respect the closed areas as dangerous conditions may be encountered in those areas,” said Dean Takebayashi, Hawaii district parks superintendent.

Cost of repairs and clean up in the park so far has been $88,045. Local tour companies will be notified about the opening.

Eruption and Lava Flow Update

This is an eruption and lava flow update for Friday December 5th at 8:00 AM.

This morning’s assessment shows that the flow front continues to show signs of advancement however has slowed. The active flow front remains approximately 2.4 miles upslope of the Highway 130 and Pahoa Village Road intersection. The flow had advanced approximately 145 yards since yesterday.

Public, Private Agencies Convene to Discuss Lava, Emergency Housing

More than 45 of Hawaii Island’s top officials in government, business, construction, academia and the non-profit sector gathered last week in Hilo to discuss the Puna lava situation and its effects on the island’s housing market.
Lava Housing

The emergency housing forum, hosted by HOPE Services Hawaii, Hawaii Island Realtors, the National Association of Residential Property Managers (NARPM) and Day Lum Rentals & Management, included roundtable discussions that focused on short- and long-term housing planning, legislative policy and expanding community resources.

The November 24 forum was intended as the beginning of a larger conversation focused on building more affordable housing on Hawaii Island. An action plan that outlines next steps and leverages private and public partnerships is being created by the forum’s hosts and expected to be complete by first quarter 2015. The plan will identify short and long-term solutions, which will help inform possible legislative policies and provide the basis for maximizing community resources.

During the forum, agency heads discussed what organizations are experiencing as a result of the lava breakout, which started in late June and has travelled 13.5 miles since. Some presented ideas to alleviate the demand for housing outside of Puna, noting, however, that today’s quick fixes should complement the island’s long-term housing and development plans.

“No one is pretending to have all the answers,” said Mayor Billy Kenoi. “There’s no lava flow manual, so many policy decisions are being made with the best information available. What we’re facing as a community is significant, but the challenges are not insurmountable. The County has been and will continue to be all hands on deck, ready to collaborate, and to share information as it becomes available to lessen anxiety and uncertainty.”

Brandee Menino, chief executive officer for HOPE Services Hawaii, said that while HOPE primarily helps homeless and at-risk individuals and families transition off the streets and obtain stable housing, her office has been getting calls from families displaced by Tropical Storm Iselle and potentially isolated by the lava. She noted that even before this year’s natural disasters, the need for rental units had been identified.

“A 2011 Housing Planning Study prepared for the Hawaii Housing Finance & Development Corporation revealed that Hawaii County would need 1,753 rental units by 2016 in order to meet the growing demand for housing,” said Menino. “This report was done in 2011, when lava was not a concern, so we must make a concerted effort to prioritize creating more affordable housing opportunities for Hawaii’s families.”

Paul Normann, executive director of the Neighborhood Place of Puna (NPP), a resource for distressed families, said Puna has the highest rate of child abuse and neglect in the State. “Because of the disruption caused by Iselle and the active lava flow, NPP has seen a dramatic increase in the number of families seeking assistance. In the first four months of the current fiscal year, July through October, NPP has already served 106 families. To put that in context, over the course of the entire 12 months of the previous fiscal year, NPP served a total of 130 families.

Nancy Cabral of Day-Lum said that some families wanted to get ahead of the lava and moved from the area. But Cabral is concerned with who haven’t. “There are a lot of residents who have not been preparing for what’s coming. It seems they are waiting for government to step in and rescue them, so we really need to take steps to ready the housing market.”

Cabral offered solutions to stave off a potential housing crisis including working with hotels to temporarily rent out rooms, helping families uproot and move homes to vacant lots and lobbying the State to relinquish control to the County of affordable units such as Lanakila Housing, which can move faster to make the units available to those looking to relocate from Puna.

Mark Kimura, an economic geography researcher at the University of Hawaii at Hilo, who conducted an informal survey of Puna residents, said almost half reported they had no one to rely on or place to go if they needed to move. 14 percent said they have already left the area or are preparing to leave and 25 percent said they could move-in with family or friends on-island. He said many don’t want to give up their homes because they are still paying a mortgage, have farms, can’t afford to move and have difficulty finding places that are pet-friendly or retrofitted for people with disabilities.

Amanda Donaldson, President of NARPM’s East Hawaii chapter, which is made up of about 20 local residential property managers, said members get nearly a dozen additional calls a day from families looking for housing outside the lava zone. She said NARPM agents are willing to add addendums that allow individuals in the lava impact zone to break their lease once lava hits.

Kehau Costa of Hawaii Island Realtors championed a “one-stop-shop” rentals website where interested renters can view available units on the island, which would speed up house hunting. Costa also suggested a “new landlord resource fair” because of the increasing number of individuals asking how they can convert part of or their entire home into a rental.

Additional ideas that came out of the forum include exploring commuter housing, house sharing, prepping lands for modular housing, fast tracking County building permit processes as well as County take over, repair and rental of foreclosure homes.

Any individuals or organizations interested in taking part in future discussions may contact Brandee Menino at bmenino@hopeserviceshawaii.org or (808) 933-6013.

Satellite Image Shows Lava Activity in Downslope Portion of Flow

The portion of the June 27th lava flow that entered Pāhoa in October is inactive, but a new lobe is advancing downslope a short distance west of the earlier flow. The leading tip of the new lobe is evident by its long smoke plume, caused by vegetation burning. A Civil Defense overflight this morning (December 2, 2014) showed that this active tip continues to move towards the northeast.

Lava Flow Advances Another 400 Yards Since Yesterday

This is an eruption and lava flow update for Tuesday December 2nd at 8:45AM.

This morning’s helicopter assessment shows that the new flow front continues to show signs of advancement and widening.   The active flow front is located approximately 2.7 miles upslope of the Highway 130 and Pahoa Village Road intersection.

The flow had advanced approximately 400 yards since yesterday.  Current activity does not pose an immediate threat to area communities and Civil Defense and Hawaiian Volcano Observatory personnel are maintaining close observations of flow activity. Residents down slope will be kept informed of any changes in flow activity, advancement, and status.

Smoke conditions were light this morning in the immediate area with all smoke from burning vegetation being blown in a southeast direction.  Smoke conditions may increase in some areas and residents that may be sensitive or have respiratory problems are advised to take precautions and to remain indoors.

The Pahoa Village Road remains open to all traffic and motorists are advised to exercise caution as some utility pole protection material remains in place.  Everyone is asked to please respect the residents of the area who were affected by the lava flow and to not trespass on private property.

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.

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.

A comparison of a normal photograph with a thermal image of the narrow channel at the leading tip of the new lobe on the June 27th lava flow. 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.
