This video clip shows typical spattering activity in Kīlauea's summit lava lake. This spattering was occurring along the eastern margin of the lake on the evening of October 5.

This video shows spattering in two locations of Kīlauea's summit lava lake. In the first segment, spattering is active in a small area in the southern portion of the lake. In the second segment, spattering on the east margin of the lake has created an overhanging ledge with dangling lava stalactites.

This morning, spattering along the eastern margin of Kīlauea's summit lava lake built an overhanging ledge that was attached to the Overlook Crater wall. In this image, a few long stalactites can be seen dangling from the overhang (lower right). These stalactites were flexible enough to be swinging back and forth.

This satellite image was captured on Thursday, September 29, by the NASA/USGS Landsat 8 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.

Left: Photo of the eastern delta showing the cracks parallel to the sea cliff. The delta is about 350-400 m (1150-1300 ft) wide and it extends about 150 m (490 ft) out from the old sea cliff. Deltas are unstable, and prone to collapse, because they are built on unconsolidated lava fragments.

Another view of the larger skylight, about 5 m or 16 ft across, showing the thin roof on the tube in this area. This image is a reminder of the hazard of approaching skylights.

A large skylight was open today on the 61g upper flow field. This morning, only the narrow skylight on the left was open. Hours later the larger area collapsed and exposed more of the swiftly moving lava stream in the tube. In this image, the skylight is about 5 m or 16 feet wide.

Lava continues to flow into the ocean at Kamokuna, however this afternoon there was no noticeable plume at the western delta (upper left). The eastern delta (center) is larger, with lava continuing to enter the ocean. A relatively small area of surface breakouts is active on the coastal plain about 1.5 km (0.9 miles) upslope from the ocean entry.

A view of the lava lake in Halema‘uma‘u Crater at dusk, taken from the rim of Halema‘uma‘u (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.

Shown here are three of the main volcanic cones (center and right) that make up the KAMAKAIA Hills on Kīlauea Volcano's Southwest Rift Zone.

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.

On September 10, 2016, Kīlauea Volcano's summit lava lake rose to within 5 m (16 ft) of the vent rim (shown above). This is the highest level the lake has reached since it overflowed the vent in April-May 2015, when lava flowed onto the floor of Halema‘uma‘u Crater, forming the dark-colored rock visible on either side of the vent.

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.

This map shows recent changes to Kīlauea's East Rift Zone lava flow field at the coast. The area of the active flow field as of September 12 is shown in pink, while widening and advancement of the active flow as mapped on September 20 is shown in red. The dashed blue line shows the pre-1983 coastline. The base is a Digital Globe image from January 2016.

This telephoto image provides a closer view of the lava lake within Halema‘uma‘u Crater and spattering on the lake surface.

During recent summit deflation, the lava lake within Halema‘uma‘u Crater dropped out of view of overlooks in Hawai‘i 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 map shows recent changes to Kīlauea's East Rift Zone lava flow field. The area of the active flow field as of September 1 is shown in pink, while widening and advancement of the active flow as mapped on September 12 is shown in red. Older Pu‘u ‘Ō‘ō lava flows (1983-2016) are shown in gray.

This map includes a georeferenced thermal image mosaic showing the distribution of active and recently active breakouts on the coastal flow field. The thermal mosaic was acquired during a helicopter overflight on September 12. The episode 61g flow field is outlined in yellow to show the extent of the flow.
