With further draining, deep opening are exposed on the eastern side of the pit floor and the lava river pouring off into a deep hole on the north side of the pit.

The ponded surface covered most of the bottom the collapse pit in the floor of Halema`uma`u, and was probably more than 100 m across.

View of Pu`u `Ō `ō and the TEB vent looking northwest. There is a distinctive separation between the two plumes coming from Pu`u `Ō `ō. The east wall vent is creating the plume closest to the east rim, and the larger plume is coming from a combination of several other vents inside the crater. The TEB vent is putting off the wispy plume in the foreground.

Spectacular eruptive activity has been occurring deep within the collapse pit in Halema`uma`u Crater at Kīlauea's summit. At times, a river of lava poured into a deeper plunge pool of lava, which had a dome fountain on its right-hand side.

Over the last several days, lava has episodically risen up to cover the bottom of the collapse pit, as shown here.

The bottom of the collapse pit is roughly 285 meters (935 feet) below the rim of Halema`uma`u, from which this photo was taken.

A particularly clear view reveals the walls of the collapse pit above the lava surface. The lava surface is roughly 200 meters (656 feet) below the floor of Halema`uma`u Crater, which is the smooth surface in the background.

The photo includes five rhyolitic units of different ages: Unforested 2-ka rhyolite of "Devils chain" rests on forested 35,000 year old flow lobe from adjacent Devils Hill dome. Three pale-gray spurs form sharp salients that extend to elevations only 550 m (1640 ft) below the darker andesitic summit of South Sister.

The "Devils chain" is a string of nearly contiguous, virtually uneroded rhyolite lava domes and flows aligned north-south along a 5 km (3 mi) stretch on the southeast apron of South Sister. The largest of these is the Newberry flow (right center, below South Sister), only 2.5 km (1.5 mi) from the summit of South Sister.

Two breakouts are visible in this photo. The nearer is the lighter colored flow at the center of the image, and it is no longer active. The other is at the base of the pali just beyond and it continues to creep slowly forward.

This is the upper-most of several active breakouts from the lava tube system that started over this past weekend. Pu`u `Ō `ō is at the upper right.

The Waikupanaha ocean entry remains active with its typical white steam plume blowing inland. The Hawaii County viewing area is marked by the white dots just below and left of the image center. The viewing area trailhead is at the white structure at the far right.
