Halemaʻumaʻu at dusk
A view of the lava lake in Halemaʻumaʻu Crater at dusk, taken from the rim of Halemaʻumaʻu (closed to the public due to volcanic hazards). The view is towards the northwest, with the broad summit of Mauna Loa near the top of the photograph. The lake was 34 meters (112 feet) below the Overlook crater rim at this time.
This video clip shows the northern portion of the lava lake, where episodic bubbling commonly occurs. The northern margin of the lake is in the upper right portion of the photo. Note how the bubbling occurs in the same general area, regardless of the movement of the crustal plates. The video is shown at 20x speed.

The rise and fall of Kīlauea Volcano's summit lava lake
Since early September 2016, Kīlauea's summit lava lake level has fluctuated, as shown in these side-by-side webcam images. On September 10 (left), the summit lava lake rose to within 5 m (16 ft) of the vent rim, only to drop the next day with the onset of summit deflation. Since then, the lava lake level has been up and down in concert with summit inflation and deflation, dropping to 30 m (98 ft) below the vent rim on September 24 (right)and as low as 36 m (118 ft) the next day. For insight on what's happening with Kīlauea Volcano's summit lava lake and what it means, check out this recent HVO "Volcano Watch" articlehttp://hvo.wr.usgs.gov/volcanowatch/view.php?id=456.

Breakouts remain active on the coastal plain
Breakouts from the the 61g lava flow remain active on Kīlauea Volcano's coastal plain, roughly 2 km (1.2 miles) upslope of the ocean entry. This photo shows a typical lobe of pāhoehoe lava filling in a small depression.
This video clip shows a few of the lava breakouts active on Kīlauea's coastal plain on September 20. The activity consisted of scattered pāhoehoe breakouts. The final segment in this video is shown at x20 speed.
Kīlauea's summit lava lake on the rise again
Left: During recent summit deflation, the lava lake within Halemaʻumaʻu Crater dropped out of view of overlooks in Hawaiʻi Volcanoes National Park. But since the switch to inflation early Sunday morning (September 18), Kīlauea Volcano's summit lava lake has been rising again, bringing the lake surface back into view. This morning the lake level was measured at 12 m (39 ft) below the vent rim, with sporadic spattering visible from the Park's Jaggar Museum Overlook. Right: This telephoto image provides a closer view of the lava lake within Halemaʻumaʻu Crater and spattering on the lake surface.

Views of the eastern Kamokuna lava delta
Under trade wind conditions, Kīlauea Volcano's eastern Kamokuna lava delta is more safely viewed from outside the closed area on the east, or Kalapana, side of the ocean entry. Today, trade winds were blowing the billowy white ocean entry plume, a mixture of superheated steam, hydrochloric acid, and tiny shards of volcanic glass, away from the viewing area. Noxious volcanic fume from the active lava tube, visible to the right of the plume, should also be avoided by staying upwind of the ocean entry, which today, was at this location.

Ocean entry and breakout on the coastal plain continue
Lava continues to flow into the ocean at Kamokuna, with two main entry areas, both forming lava deltas. The eastern lava delta is the larger of the two, and today, a broad span of small lava streams entering the sea was creating a wide ocean entry plume. The smaller western entry was feeding a weaker plume.
Left: Another view of the ocean entries, with the eastern entry in the foreground. For scale, a boat can be seen in the lower left portion of the image. Right: A breakout from the base of the pali, which began last week, remained active today, with scattered pāhoehoe lobes near the eastern margin of the 61g lava flow. Fume from the lava tubes on the pali can be seen in the upper left part of the image.

Halemaʻumaʻu lava lake exceptionally high
Left: Kīlauea's summit lava lake rose to within about 5 m (16 ft) of the floor of Halemaʻumaʻu Crater this morning, before dropping back down slightly with the onset of spattering. This view, taken from the east edge of Halemaʻumaʻu, shows spattering at the south corner of the lava lake. Right: Zoomed in view of the spattering at the south edge of the lava lake. Note the black high-lava mark from this morning on the wall just behind the spattering.

Ocean entry activity continues
Lava continues to flow into the sea at the Kamokuna ocean entry. This photograph, taken from the eastern margin of the lava flow, shows the eastern ocean entry site and the lava delta that has formed there. Today, several small streams of incandescent lava could be seen spilling into the water, with occasional small explosive bursts occurring in the surf.

Kīlauea's lava lake at high level
On Wednesday evening (September 7), the lava lake at Kīlauea's summit reached a high level, about 8 m (26 feet) below the floor of Halemaʻumaʻu Crater. This panorama shows the former Halemaʻumaʻu Overlook (closed since 2008 due to volcanic hazards) at the far left. Jaggar Museum, visible on the skyline in the upper right part of the photo, is a popular destination in Hawaiʻi Volcanoes National Park for viewing the lava lake activity and spattering lake surface.
A closer look at Kīlauea's summit lava lake on Wednesday evening, around 6:30 p.m., when the lake was just 8 meters (26 feet) below the floor of Halemaʻumaʻu Crater.

Beautiful morning at the summit of Kīlauea
Kīlauea Volcano's lava lake within Halemaʻumaʻu Crater rose steadily over the past day in concert with summit inflation. This morning, with the lake level at just 19 m (62 ft) below the summit vent rim, vigorous spattering on the lake surface was visible from the Jaggar Museum Overlook in Hawaiʻi Volcanoes National Park.

Beautiful day on Kīlauea Volcano's East Rift Zone
Left: Calm after the storma beautiful day on Kīlauea Volcano's East Rift Zone. Rain from Hurricane Madeline had little impact on Puʻu ʻŌʻō, shown here, or lava flow 61g. Right: View of the lava pond within the Puʻu ʻŌʻō west pit crater, which is about 50 m (164 ft) across. Weak spattering on the lava pond surface, about 23 m (75 ft) below the crater rim, is visible through the thick volcanic gas cloud.
Left: An aerial view of a new breakout (light-colored flow at center of image) from the 61g tube. The breakout began with some vigor on the morning August 29, but today it was sluggish, with only a few scattered pāhoehoe toes still active on the margins of the flow. Right: Close-up view of one of the small toes of pāhoehoe still active on the new breakout from the 61g lava tube, which began on Monday, August 29.
Left: View of the 61g flow field, from Puʻu ʻŌʻō (visible on top, left horizon) to the westernmost ocean entry at the coast, where lava spills into the sea, creating a lava delta. Fume emanating from the flow fieldon the coastal plain (above the ocean entry) and high on the pali (cliff) in the far distancedelineate part of the active tube system that carries lava from the Puʻu ʻŌʻō vent to the sea. Right: A closer view of where lava is entering the sea along a 1.1-km- (0.7-mi-) wide section of the coastline. There is no evidence that high surf from Hurricane Madeline had any impact on the lava deltas that have formed, and continue to grow, at the ocean entries. Discoloration of the ocean water is caused by fragments of volcanic glass, which are produced when hot lava enters cool seawater and shatters into tiny pieces that are carried by currents along the shore.
