Sluggish pāhoehoe breakouts advance slowly on coastal plain

The flow front remains active and consists of slowly advancing pāhoehoe. There are scattered breakouts along the margins of the flow on the coastal plain and base of the pali. During the overflight today, the flow front was 730 m (0.45 miles) from the ocean.

A faint double rainbow provided a beautiful backdrop for sluggish pāhoehoe lava oozing out from near the flow front this morning.

During early morning field observations, a large breakout of lava near the base of Pūlama Pali (steep fault scarp in background) was visible through fumes from the lava tube and heat shimmer from lava on the coastal plain. The approximate location of the lava tube feeding Kīlauea's active lava flow is visible as degassing sources (white fume) on the pali.

Lava flow on coastal plain still active

Left: Kīlauea Volcano's lava flow remains active, with pāhoehoe lobes, like the one shown here, slowly advancing on the coastal plain. Breakouts upslope of the leading edge continue to widen the flow margins. Today, the active flow front was approximately 850 m (0.5 miles) from the ocean, and 720 m (0.4 miles) from the road. Right: The HVO field crew mapped new breakouts on the lava flow by recording GPS points along the active flow margin.

Vigorous spattering on Kīlauea summit lava lake

Left: A long, hot hike was not needed to see red lava today. Vigorous spattering from Kīlauea Volcano's summit lava lake was visible from the Jaggar Museum Overlook in Hawaiʻi Volcanoes National Park as of this afternoon. The lava lake surface, measured at 25 m (82 ft) below the vent rim this morning, was high enough for the spattering to be seen from afar. Right: A zoomed-in view of the lava lake spattering.

Flow front remains active on coastal plain, but little forward movement

The flow remains active on the pali and coastal plain, with scattered breakouts of pāhoehoe lava. Over the past week, however, the leading tip of the flow has advanced only a short distance. Today, the flow front was 850 m (0.5 miles) from the ocean. In this photograph, the current lava flow is the lighter color area in the center of the photo.

Left: Only a few short sections of road in Royal Gardens subdivision remain uncovered by lava. In this kipuka, about 200 m (220 yards) of Orchid Street is still exposed. Right: This photograph looks downslope at the uppermost section of the Episode 61g flow. The vent is in the lower left corner of the photo. Several collapses have occurred over the lava tube, and the trace of the tube can be seen by the fuming sources extending downslope.

The large hole on the northeast flank of Puʻu ʻŌʻō remains open, providing a view of forked lava streams. Since the last overflight on Friday, July 15, the lava streams have started to crust over, reducing the glow in the pit.

Flow front slowly advancing

The flow front remains active on the coastal plain, but has only moved about 60 m (~200 ft) closer to the ocean in the past three days. As of midday on July 15, the slow-moving pahoehoe is roughly 870 m (~0.5 mi) from the ocean. Activity upslope continues to widen the flow margins. The light gray surface in this image is the new pahoehoe of the 61G flow.

Flow front activity persists, but advance still slow

Surface breakouts remained active on the pali and coastal plain, but the leading tip of the flow has advanced little since mapping on Sunday. This morning, the flow front was about 940 m (0.6 miles) from the ocean. Activity upslope of the flow front was widening the flow margins. In this photo, the active flow is the lighter colored area.

Above the pali there are no surface breakouts, and lava is carried downslope within the subsurface lava tube system. The trace of the lava tubes is evident by the line of fuming point sources along the flow. Puʻu ʻŌʻō, and the vent for the current flow, are in the upper left portion of the photo.

Flow front advance on coastal plain slows further

The leading tip of the flow has moved only 40 m (130 feet) since yesterday's mapping and the lava activity at the tip was still very weak. The leading lava lobe had a dull surface and rough texture suggesting that it may have cooled somewhat within the flow interior.

About 200 meters (yards) upslope of the leading tip of the flow, more typical pāhoehoe was present - with a shiny, smooth surface.

Flow front continues slow advance on coastal plain

The flow front activity was relatively weak today, but still active and advancing. The flow front at midday was about 1 km from the ocean (0.6 miles), having moved about 130 m (140 yards) since yesterday's mapping.

Flow front slows down on the coastal plain

After rapidly advancing across about half of the coastal plain, the flow front slowed considerably over the past day. The front moved only moved about 90 m (300 feet) since yesterday's mapping, and activity at the leading tip of the flow was fairly weak today. The position of the lava flow front relative to the shoreline can be seen in this aerial photograph. The leading edge of the flow, which was 1.1 km (0.7 miles) from the ocean today, is the light-colored area near the center of the image.

More vigorous breakouts were active upslope, near the base of the pali. Fume from the lava tubes and smoke from burning vegetation are visible on the pali in the upper part of the photo. Puʻu ʻŌʻō is visible on the upper left skyline.

Channelized ʻaʻā lava flows were still active on the steep sections of the pali. Dark brown areas are recently active ʻaʻā, and the shiny gray areas are pāhoehoe lava.

Left: A deep hole remains open on the upper northeast flank of Puʻu ʻŌʻō, revealing a forked stream of swiftly moving lava (just visible in this photo). Puʻu ʻŌʻō crater is visible in the upper part of the photo. Right: A wider view of the fume-filled crater at Puʻu ʻŌʻō. The deep hole near the crater rim (see photo at left) is just left of center in this image.

Flow front slowly advancing across coastal plain

The flow front remains active, and consists of slow-moving pāhoehoe lava. This afternoon (July 7) the flow front was roughly 2.2 km (1.4 miles) from the base of the pali, 1.2 km (0.7 miles) from the ocean, and 1 km (0.6 miles) from the road.

Flow front more than halfway across coastal plain

The flow front remains active, and was more than half way across the coastal plain today (July 6). This afternoon, the flow front was roughly 2 km (1.2 miles) from the base of the pali, and 1.3 km (0.8 miles) from the ocean. The front consisted of slow moving pāhoehoe.
