With brisk trade winds today, spectacular views of Kīlauea Volcano's eastern Kamokuna lava delta were possible from outside the closed area on the east, or Kalapana, side of the ocean entry.

It is possible to see the skylight without entering the closed area, and with a camera or smart phone, you can zoom in for more detail, as shown in this image.

Another collapse feature and skylight along the lava tube that feeds the Kamokuna ocean entry, underscoring the hazards associated with active lava tubes and the need to remain outside the closed area.

A telephoto image of the skylight, captured without entering the closed area. Note the sagging lava surface in the foreground, an indication of just how unstable this area is.

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 photograph shows spattering at the southeast margin of Kīlauea's summit lava lake, as viewed from the west. This is the most common area on the lake to have spattering, but, because it is almost directly below the camera location, it is not visible in our webcam images.

The KALAHIKIOLA Congregational Church in KAP‘A‘āU was extensively damaged on October 15, 2006, by two earthquakes (magnitudes 6.7 and 6.0) off the northwest coast of Hawai‘i Island. The earthquakes were felt throughout the State of Hawaii, but the greatest damage occurred in the North Kona and Kohala Districts of the Island of Hawai‘i.

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.

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.

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.

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 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.

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.

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.

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.

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.
