June 27 lava flow remains active in forest northeast of Puʻu ʻŌʻō

The June 27 lava flow remains active as a narrow lobe pushing through thick forest northeast of Puʻu ʻŌʻō, triggering small brush fires. This view is to the east, with the forested cone of Heiheiahulu partly obscured by the smoke plume from this angle. The flow front today was 8.7 km (5.4 miles) northeast of the vent on Puʻu ʻŌʻō.

Left: The surface flows active at the front of the June 27 lava flow are fed from lava flowing through a lava tube. This collapse of a portion of the roof has produced a skylight, and a direct view of the fluid lava stream several meters (yards) beneath the surface. Right: A remarkable perched lava pond was active on the June 27 lava flow more than a month ago. On August 12 a small lava flow erupted from the rim of the inactive pond, with the flow presumably originating from fluid lava that remained in the perched pond interior. This type of flow is commonly erupted from perched lava ponds and small lava shields, and we informally refer to these as "seeps". The seeps have a characteristic spiny, toothpaste-like, flow texture. Today, this seep was inactive, but the flow interior remained incandescent. The front of this small flow can be seen at the top of the photograph.

June 27 flow continues advancing through forest northeast of Puʻu ʻŌʻō

The June 27 flow remains active, and has advanced further into the forest over the past week. The flow front today was 8.5 km (5.3 miles) northeast of the vent on Puʻu ʻŌʻō (see "map" link above for current flow field map). The flow's continued brisk advance rate is likely related, in part, to its continued confinement by local topography. Today, the narrow flow front was within one of the many linear depressions (grabens) on the East Rift Zone. Puʻu ʻŌʻō can be seen in the distance.

Left: Another view of the flow front, looking east. The small bump on the horizon, near the center of the photograph, is the forested cone of Heiheiahulu. Right: Portions of the June 27 lava flow continue to expand and cover older flows from Puʻu ʻŌʻō.

Left: Thick fume continues to obscure views into Puʻu ʻŌʻō Crater with the naked eye. The thermal camera has proven useful recently to see the hidden activity, which includes several small lava ponds (see thermal image from the July 29 overflight, below). Right: A skylight reveals the fluid lava stream within the main tube on the June 27 lava flow. The recently active perched lava pond is in the upper left portion of the photograph.

A closer look into the skylight on the June 27 lava flow, revealing complex structure within the lava tube. The bright incandescent area is the fluid lava stream, which was slowly but steadily flowing through the tube.

Lava lake activity continues in Halemaʻumaʻu Crater

The usual lava lake activity continues in Halemaʻumaʻu Crater with no major changes related to the recent hurricane. This afternoon the lake surface was about 40 meters (130 ft) below the floor of Halemaʻumaʻu Crater, which has been typical over the past several weeks. Lake surface migration was from north to south (top of photo to bottom), and occasional gas bubbles were bursting through the crust.

June 27 lava flow reaches forest boundary

The June 27 flow continues to advance at a brisk rate, and has reached the forest boundary over the past week. On today's overflight, thick plumes of smoke from burning vegetation partially obscured the flow front. See the "maps" link above for today's flow field map.

June 27 lava flow advance rate increases

The June 27 flow front has advanced more rapidly over the past four days, and is now 4.2 km (2.6 miles) from the vent. This recent increased advance rate is due to the confinement of the flow against the slopes of an older perched lava channel, from 2007. The advance rate will likely drop in the coming days as the flow passes the confines of the perched channel and spreads out on flatter topography.

Left: Another view of the front of the June 27 flow, looking northeast. The flow front has narrowed as it has been confined against the slopes of the 2007 perched lava channel, and this is associated with a higher advance rate of the flow front over the past four days. Right: View, looking southwest, of Puʻu ʻŌʻō and the new perched lava pond. Puʻu ʻŌʻō is the fume-filled crater in the top half of the image. The circular feature in the lower portion of the photograph is the perched lava pond active earlier this month, which was fed by the June 27 lava flow. This perched lava pond is now inactive, but the June 27 flows continue to advance towards the northeast (see other photos from today).

Visual-thermal comparison of Puʻu ʻŌʻō crater, looking west. In the normal photograph on the left, large portions of the crater floor are obscured by thick volcanic fume. The thermal image on the right can "see" through this fume, revealing features in the crater. Over the past month, a large portion of the crater floor has subsided. Within this triangular subsidence area, three small lava ponds were active today. Two are visible in this thermal image, while a third (near the South lava pond) is blocked by a steep wall from this angle.

Puʻu ʻŌʻō crater at dawn

A time-lapse camera on the rim of Puʻu ʻŌʻō crater captured this image at dawn. The view is towards the southeast, and shows two glowing pits in the southern portion of the crater floor. Our overflight the next day showed that these pits are filled with small lava ponds.

Rockfall triggers explosive event at Halemaʻumaʻu

Just after 10 AM this morning, the southeastern wall of the Overlook crater, in Halemaʻumaʻu, collapsed and fell into the summit lava lake. This triggered a small explosive event that threw spatter bombs onto the rim of Halemaʻumaʻu at the site of the tourist overlook, closed since 2008. This image is a still taken from the webcam positioned on the rim of Halemaʻumaʻu at that location, showing spatter in the air directly in front of the camera.

Left: The lava fragments ejected ranged in size from dust-sized particles up to spatter bombs about 70 cm (~30 inches) across. The larger clasts the bombs dotted the ground around the tourist overlook and webcam, giving the area a look reminiscent of a cow pasture. Right: As has been seen with almost all previous explosive events at Halemaʻumaʻu since 2008, the spatter that was ejected was coated in dust and filled with small lithic fragments clear evidence of the involvement of lithic wall rock. The knife is 12 cm (4.5 in) long.

Left: Spatter landed on wooden fencing laying on the ground at the closed tourist overlook, igniting it in a few places. Right: The part of the Overlook crater wall that collapsed is evident in the center of this photo by its white color.

New crater at Puʻu ʻŌʻō

Left: Since the onset of the "June 27 breakout" flow, the central part of Puʻu ʻŌʻō's crater has been collapsing slowly. Thick fume and steam prevented good views, but this photo shows the edge of the ring fracture that bounds the collapse. The heavy fume comes from pits that formed where spatter cones used to be. The view is toward the east; the "June 27 breakout" flow starts near the left side of the photo, marked by thin bluish fume. Right: Perhaps the most interesting feature in the new crater at Puʻu ʻŌʻō is the pit formed on the southern side of the crater floor. There, a small lava pond roughly 10 m (~30 ft) across has been sporadically overflowing and sending lava toward the deeper central part of the crater. View is to the south.

Inactive perched lava pond and the new lava tube

Left: After the June 27 breakout started, a perched lava pond looking something like a giant above-ground swimming pool grew over the main vent. Notice the nearly flat upper surface of the now-inactive pond just above and to the left of center, and the relatively steep levee which contained the pond. The pond was abandoned after lava broke from a new spot near the west edge of the pond. That flow has begun constructing a lava tube, its trace marked by the fume to the right of the perched pond. The view is toward the southeast. Right: Here is steeper view of the inactive lava pond, just left of center. After it was abandoned, its surface crusted over and sagged to form a gentle bowl. Skylights and points of fume just right of center mark the trace of the new tube. Puʻu ʻŌʻō is at upper right. The view is toward the south-southeast.

Terminus of new flow near Kahaualeʻa

Left: The front of the "June 27 breakout" flow, seen here as the silvery lava at lower right, is about 2.0 km (~1.2 miles) northeast from its vent (as measured in a straight line), and surrounds what little remains of Puʻu Kahaualeʻa, a forested cone several hundred years old. View is toward the southwest, and Puʻu ʻŌʻō is at upper right. Right: Here is a closer view showing the beleaguered Puʻu Kahaualeʻa surrounded by active Pāhoehoe flows. The view is to the northwest.

A new lava shield is being built on Puʻu ʻŌʻō

The June 27 breakout has remained active over the past week, emitting short lava flows from the vent on Puʻu ʻŌʻō's northeast flank. These flows have stacked upon one another creating a lava shield, which now hosts a lava pond. This before and after comparison from our webcam east of Puʻu ʻŌʻō shows the dramatic change to the skyline that this new lava shield has created.
