June 27th lava flow remains active

The June 27th lava flow remains active, with no significant advancement of the flow front since Friday, Oct 17. The flow is active along the northern boundary of Kaohe Homesteads subdivision, with brush fires along the flow margins creating thick plumes of smoke. The flow front today was 1.1 km (0.7 miles) from the closest point on Apaʻa St., as measured along a straight line. Although there has been little net advancement of the flow front over the past week, breakouts persist behind the flow front.

A comparison of a normal photograph of the flow front with a thermal image. Although the leading edge of the flow has advanced only a slight amount over the past week (about 100 m, or 110 yards), active portions behind the flow front have moved at a faster rate. Surface flows along the southern margin of the flow have advanced 575 m (630 yards) over the past week, and are now close to the leading edge of the flow. The thermal image shows that other breakouts are scattered behind the flow front.

Left: Upslope from the flow front, several breakouts are active around the crack system. These surface flows (marked by the smoke plumes) have filled in a ground crack that is immediately north of another crack. The southern crack, marked by the white dotted line, is the main crack that lava is traveling along below the surface. The lava is moving deep within this crack over a span of about 1.5 km (nearly one mile), before it surfaces at a pad of lava visible at the bottom of the photograph. Right: Puʻu ʻŌʻō Crater remains filled with thick fume, but recent views with the naked eye and thermal camera confirm that little change has occurred in the crater over recent weeks. The fume masks a handful of small incandescent openings on the crater floor.

Small explosion of spatter from the lava lake in Halemaʻumaʻu Crater

Left: A collapse of rock from the wall of Halemaʻumaʻu Crater occurred yesterday (Sunday, October 19) around 1:15 am, with rocks impacting the lake and triggering an explosion of spatter. The scar left by this collapse is visible as the light-colored area marked in the photo. The spatter fell around the Halemaʻumaʻu Overlook, which is within an area closed to the public due to hazards like this. For scale, the lava lake is about 160 m (175 yards) wide from this angle. Right: This Quicktime movie shows the small explosion of spatter that occurred at Halemaʻumaʻu on Sunday, October 19. Spatter landed around the Halemaʻumaʻu Overlook (closed to the public).

Very little advancement of the flow's leading edge, but breakouts persist around flow front

The June 27th lava flow remains active, but has advanced only a minor distance - about 50 m (55 yards) - over the past two days. Activity persists around the flow front, however, with numerous scattered breakouts. The flow front this morning was 1.1 km (0.7 miles) from Apaʻa St., as measured along a straight line.

Left: Another view of the flow front, looking downslope towards Pāhoa. The smoke plumes are created by individual breakouts burning vegetation at the flow margin. Right: A closer look at the flow front, showing the leading edge moving through thick vegetation.

Flow front advancement slows, but active breakouts persist near the front

The June 27th lava flow advancement has slowed, with the leading edge of the flow moving only a few tens of meters (yards) over the past two days. Nevertheless, active breakouts persist around the flow front, as shown in this photo by the continued burning of vegetation along the flow margins. This morning, the flow front was 1.1 km (0.7 miles) from Apaʻa St., as measured along a straight line.

The thermal image clearly shows the distribution of active breakouts (white and yellow areas), which are scattered at the leading edge of the flow but are also present up to about 1.8 km (1.1 miles) behind the flow front.

Left: Although the advancement of the leading edge of the June 27th flow has been minor over the past two days, a view into a skylight on the lava tube today showed that lava in the tube was still swiftly moving downslope towards the flow front. Right: Puʻu ʻŌʻō Crater remains filled with thick fume, and activity in the crater has not changed significantly over the past week. In the lower portion of the photograph, a line of fume sources marks the path of the June 27th lava tube. The broad circular feature in the left portion of the photograph is the perched lava pond that was active in July.

June 27th lava flow remains active, continues advancing northeast

The flow front remains active, with continued slow advancement towards the northeast over the weekend. The flow front today was 1.1 km (0.7 miles) upslope from Apaʻa St. and 2.2 km (1.4 miles) from Pāhoa Village Road, as measured along a straight line. This photo, looking down flow and taken at a low altitude, shows the flow front direction relative to the transfer station and Pāhoa.

A view of the flow front from a normal camera (left) as well as from a thermal camera (right). The white box shows the extent of the thermal image. The thermal image shows that breakouts are active at the leading tip of the flow, and are also scattered upslope from the flow front.

Left: Active breakouts are also scattered around the area that lava first entered ground cracks. The smoke plumes mark spots where individual breakouts are burning vegetation. Right: Activity in Puʻu ʻŌʻō today remains similar to what we have observed during recent weeks. Several pits on the crater floor had small incandescent holes, and there appeared to be a small lava pond in the southern pit.

This Quicktime movie provides a brief aerial overview of activity at the flow front.

Flow front continues advancing northeast, triggers brush fire

The June 27th lava flow remains active, and the flow front continues to advance towards the northeast along the forest boundary. Today, the flow front consisted of a narrow lobe moving through thick forest. The flow front was 1.7 km (1.1 miles) upslope of Apaʻa St., and 2.7 km (1.7 miles) from Pāhoa Village Road. The lava flow also triggered a brush fire that was active north of the flow front this afternoon.

Satellite image shows update on flow front position

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. For reference compare the flow outline shown here in yellow to the large-scale flow field map provided in the "maps" link above. The grid shows coordinates in Universal Transverse Mercator, with a grid spacing of one kilometer (0.6 miles).

The flow front remains active. The satellite image shows that active lava at the flow front has advanced approximately 240 meters (790 ft) beyond the point where it was mapped on Friday, October 3 (yellow line). The flow front today was 1.8 km (1.1 miles) from Apaʻa St.

Slow advancement of flow front continues

Active breakouts continue at the flow front, with about 270 m (roughly 300 yards) of advancement since Wednesday, October 1. The flow front this morning was 2 km (1.2 miles) upslope from Apaʻa St. and 3 km (1.9 miles) from Pāhoa Village Road.

Breakouts continue upslope of the flow front, around the area where lava first entered ground cracks (about halfway between the Puʻu ʻŌʻō vent and the flow front). Today, several new, but small, breakouts were active in this area.
