Aerial view of Pu‘u ‘Ō‘ō and surrounding features.

A channelized flow was being erupted today from the vent on the west side of the floor of Pu‘u ‘Ō‘ō.

Map showing the extent of the active flows of the Kamoamoa eruption, which started on March 5, 2011. Bright red shows the currently active flow, and light red shows an incomplete mapping of recent, but inactive, flows. Dark gray is the exposed area of flows erupted between 1983 and 1992, while light gray shows the extent of flows erupted from 1992 to 2007.

At 2:31pm today, another large chunk of the rim collapsed into the Halema‘uma‘u lava lake.

Just moments after the last photograph, the 2:31pm collapse produced a thick brown plume, but did not appear to trigger an explosive event in this case.

Lava spatters above the fissure just west of the base of Pu‘u ‘Ō‘ō.

Most of the day's activity was focused at this vent, around which a low cone was forming. Pu‘u ‘Ō‘ō is visible in the background to the northeast.

Lava pours from the fissure just after daybreak and cascades out of sight into a deep crack. HVO geologist near upper right for perspective.

This fissure is erupting 1.5 km (0.9 mi) west of Pu‘u ‘Ō‘ō Crater. You can view this eruption on the new Pu‘u ‘Ō‘ō to Nāpau Crater webcam installed today!

Incandescent rubble rolling and sliding down the scarp on the edge of the collapsing crater in Pu‘u ‘Ō‘ō. A remnant of the pre-collapse crater floor can be seen in the background below the crater's south wall. The east rim of Pu‘u ‘Ō‘ō is in the foreground.

Fissures actively propagating during Kamoamoa eruption, Kīlauea, Hawai‘i. View looking at the NE end of the actively propagating fissure. Lava is just breaking the surface in foreground crack. Lava reached the surface along an actively propagating fissure during Kīlauea Volcano's Kamoamoa eruption on March 5, 2011.

Map shows activity from Episode 56

Following several collapses and small explosive events that deposited spatter on the floor of Halema‘uma‘u crater around noon today, the lava surface in Halema‘uma‘u was roiling and agitated for the remainder of the afternoon, with numerous points of upwelling and spattering.

New fissure eruption SW of Pu‘u ‘Ō‘ō between Pu‘u ‘Ō‘ō and Nāpau crater. Spatter is reaching 15-20 m into the air, above the trees.

These tephra deposits are from the Kulanaokuaiki Tephra erupted from Kīlauea Volcano about 200 to 1000 C.E. The base of a lava flow overlying the tephra is just above the person's hand. This site is located near the base of Kīlauea's summit crater wall, directly below the USGS Hawaiian Volcano Observatory and NPS Jaggar Museum.
