The area of the flow on September 12, 2014, at 12:30 PM is shown in pink, while widening and advancement of the flow as mapped on September 15 at 2:00 PM is shown in red. The front of the active flow was 15.5 km (9.6 miles; straight-line distance) from the vent and had crossed the Wao Kele o Puna Forest Reserve boundary into the vacant northwest corner of Kaohe Homesteads.

The flow front was advancing toward the northeast and was 4.3 km (2.7 miles) upslope from Pāhoa Village Road. The actual length of the flow, measured along the lava tube axis (so that bends in the flow are considered) is 17.7 km (11.0 miles).

The blue lines show down-slope paths calculated from a 1983 digital elevation model (DEM). For an explanation of down-slope path calculations, see: http://pubs.usgs.gov/of/2007/1264/. Down-slope path analysis is based on the assumption that the digital elevation model (DEM) perfectly represents the earth’s surface. But, DEMs are not perfect, so the blue lines on this map indicate approximate flow path directions.

The purple arrow shows a short term projection of flow direction based on the flow behavior over the past several days and the local topography. All older Puʻu ʻŌʻō lava flows (1983–2014) are shown in gray; the yellow line marks the lava tube.

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.

Lava Smoke and Steam Now Visible From All Over East Hawaii

Puna and in particular the city of Pahoa is battening down the hatches as this lava flow approaches our district.

Here is a picture from my front yard this morning around 6:15 this morning:

The orange color is the reflection of the lava off the smoke that is being created from the flow.

New USGS Maps Released – Where the Lava Flow is Now

This small-scale map shows the June 27th flow in Kīlauea’s East Rift Zone on September 12, 2014.

The area of the flow on September 10, 2014, at 2:45 PM is shown in pink, while widening and advancement of the flow as mapped on September 12 at 12:30 PM is shown in red. The front of the active flow was 14.9 km (9.3 miles; straight-line distance) from the vent and 0.17 km (0.1 miles) from the east boundary of the Wao Kele o Puna Forest Reserve. The actual length of the flow, measured along the lava tube axis (so that bends in the flow are considered) is 17.1 km (10.6 miles). The flow was advancing toward the northeast. The blue lines show down-slope paths calculated from a 1983 digital elevation model (DEM). For an explanation of down-slope path calculations, see: http://pubs.usgs.gov/of/2007/1264/. All older Puʻu ʻŌʻō lava flows (1983–2014) are shown in gray. Down-slope path analysis is based on the assumption that the digital elevation model (DEM) perfectly represents the earth’s surface. But, DEMs are not perfect, so the blue lines on this map indicate approximate flow path directions.

This shaded-relief map, with digital surface data provided by the Carnegie Airborne Observatory, shows some of the cracks, faults, and grabens (down-dropped blocks between adjacent faults; http://earthquake.usgs.gov/learn/glossary/?term=graben) that are present in Kīlauea’s East Rift Zone, and which have partly controlled the June 27th flow’s advance direction. The June 27th flow as of September 10, 2014, at 2:45 PM is shown in pink, while flow advance since then (as of ~12:30 PM on September 12) is shown in red. At the time of the mapping, the flow was advancing toward the northeast. (see large map)

Lava Flow Moving to the Northeast

June 27 flow moving to the northeast

As of Friday afternoon, September 12, 2014, the most distal front of the June 27th lava flow had reached a straight-line distance of 14.9 km (9.3 miles) from the source vent on the northeast flank of the Puʻu ʻŌʻō cone. The flow has continued in the northeast direction that it assumed in the middle of the week and is now only 171 meters (0.1 miles) from the boundary of the Kaohe Homesteads community. The flow is still within thick forest, so that dense plumes of smoke are created as vegetation is consumed. Small breakouts (visible as plumes in the middle distance) are also active closer to Puʻu ʻŌʻō, roughly midway along the length of the June 27th flow.

The vent for the June 27th flow is on Puʻu ʻŌʻō, which can be seen at the top of the normal photograph. After pouring in and out of ground cracks in late August, the flow finally emerged from the cracks around September 3 and began spilling out towards the north. The northwest portion of Kaohe Homesteads subdivision can be seen in the lower left of the images.

Lava Flow Estimated to Cross Highway 130 in Two Weeks

The Office of Hawaiian Affairs and Department of Land and Natural Resources announce the immediate closure of Wao Kele o Puna Forest Reserve, until further notice, due to the hazards associated with the June 27 lava flow. Wao Kele o Puna is owned by OHA and managed by DLNR.

I would hardly call it a crime scene!

I would hardly call it a crime scene!

Kamana‘opono Crabbe, Ka Pouhana, OHA (Chief Executive Officer) said, “It is prudent at this time to close Wao Kele o Puna due to lava activity and subsequent unsafe conditions.

William J. Aila, Jr., DLNR Chairperson said, “We join with Hawaii Civil Defense and Hawaii Volcanoes National Park to warn the public of extreme danger from lava flowing through cracks in Wao Kele O Puna, and Kahauale’a Natural Area Reserve. Both areas are off-limits to all persons. We will prosecute anyone entering these areas for any purpose, including unauthorized lava sightseeing tours. Hikers have been lost or injured in these areas, and personnel called in to rescue them have also been put in danger.”

The Division of Forestry and Wildlife (DOFAW) will be assisting Hawaii County to build the alternate roads in Puna.

Lava is estimated to cross Highway 130 in approximately two weeks if it stays on its current path.

DOFAW will provide a D8 bulldozer and equipment operator to Nanawale/Railroad Ave. tomorrow and expect work will take several weeks. Portions of the old railroad right-of-way run through state forest and unencumbered lands. Railroad Ave. bisects Nanawale state Forest Reserve

President Obama Issues Major Disaster Declaration for Hawaii and Maui Counties

Today, President Obama issued a major disaster declaration for the State of Hawai‘i activating the release of federal funds to help communities recover from Tropical Storm Iselle that occurred from August 7-9, 2014.

People waited for hours just for basic supplies during Iselle.

People waited for hours just for basic supplies during Iselle.

“This is great news for the thousands of people in Puna who were affected by Iselle,” Senator Schatz said.  “This federal assistance is critical to supporting our communities’ ongoing recovery. I thank President Obama for recognizing the critical needs of the many families still rebuilding in Puna.”

“I thank President Obama for issuing a major disaster declaration for the State of Hawai‘i,” said Senator Hirono. “Families and the community continue to rebuild after Tropical Storm Iselle hit over a month ago and much of the damage to our farms and homes will take many years to rebuild.  Similar to how our communities came together during the disaster, we’ll continue to come together during recovery. I look forward to the ongoing work with my colleagues in our joint effort to help ensure people get the resources they need to rebuild.”

All areas in the State of Hawai‘i are eligible to apply for assistance under the Hazard Mitigation Grant Program.

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 Moves Closer to Pahoa and Highway 130

The June 27th lava flow remained active Wednesday afternoon, September 10, 2014, with the most distal flow front 14.5 km (9.0 mi; straight-line distance) from the vent on the northeast flank of the Puʻu ʻŌʻō cone, which is visible in the far background.

Click to enlarge

Over the past day, the flow front direction shifted from a north trend to a more northeast trend, bringing the flow closer to the Forest Reserve boundary. The flow continued to advance through thick forest, creating smoke plumes as it engulfed trees and other vegetation. The smell of smoke has been detected far downwind of the flow, but fires are not spreading beyond the margin of the flow. Small, sluggish breakouts of lava (smoke plumes in far distance) also remain active closer to Puʻu ʻŌʻō, roughly midway along the length of the June 27th flow.

View from above the end of the June 27th lava flow, looking along its northeast trend through the Wao Kele o Puna Forest Reserve.

On the afternoon of September 10, 2014, the flow front was 0.6 km (0.4 mi) from the boundary between the Forest Reserve and Kaohe Homesteads, visible at far right. Click to enlarge

Smoke plumes indicate the location of the June 27th lava flow, which was 0.6 km (0.4 mi) from the edge of Kaohe Homesteads, visible in foreground, on September 10. The flow was advancing toward the northeast.

Albizia Tree Presentation at UH Hilo

The University of Hawaiʻi at Hilo Faculty Congress and the College of Continuing Education and Community Service (CCECS) invite the public to a free presentation on the invasive Albizia trees. The presentation will be held on Wednesday, September 17, from 6:30-7:30 p.m. in the University Classroom Building (UCB) Room 100.

Workers clear Albizia trees from a road following Hurricane Iselle.

Workers clear Albizia trees from a road following Hurricane Iselle.

“The fast-growing Albizia trees have had a serious ecological impact on native forests,” said Springer Kaye, Big Island Invasive Species Committee (BIISC) Manager. “They also pose a real and immediate threat to the public’s safety and welfare as we saw in the aftermath of Tropical Storm Iselle.”

Kaye and Dr. Flint Hughes, research ecologist, of the USDA Forest Service Institute for Pacific Islands Forestry, will discuss community-based efforts involving State and local agencies, lawmakers, Hawai’i Electric Light Company, and other stakeholders to remove hazardous trees, and deploy field staff and volunteers to manage non-hazardous trees. Other topics of discussion include lessons learned and future steps to achieve long-term hazard mitigation.

Parking on the UH Hilo campus is free after 4 p.m. A map of the campus can be found online at http://hilo.hawaii.edu/uhh/maps.php.

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 steam plume as seen from my house near Pahoa High School.

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.
