Map showing the extent of the "July 2007 eruption", or Episode 58, flow field relative to surrounding communities. Reddish-brown is the active flow as mapped on January 13, 2011, while bright red shows the advancement of the flow from January 13-February 4. Light red represents older flows erupted during Episode 58 of the ongoing East Rift Zone eruption.

Map showing the extent of the active flows. Reddish-brown is the flow as mapped on February 4, 2011, while bright red shows the advancement of the flow from January 13-February 4. Small ocean entries remains active at the front of both the western and eastern branches of the flow.

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

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

Early morning view of the fissure eruption between Nāpau Crater and Pu‘u ‘Ō‘ō. View is to the northwest. Fume from the eruptive vent in Halema‘uma‘u can be seen at upper right against the dark mass of Mauna Loa.

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.

A portion of charred, lava covered forest along the east rift zone, from the initial fissure eruption that began yesterday evening (March 5).

A small fissure eruption between Pu‘u ‘Ō‘ō Crater and Nāpau, extending 100 m long (330 ft) and spattering 20 m (66 ft) high.

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!

A close-up of the fissure just west of Pu‘u ‘Ō‘ō Crater. Spatter was reaching heights of 40 m (130 ft).

Photo taken at dawn of a fissure erupting between Pu‘u ‘Ō‘ō Crater and Nāpau.

This fissure began in the early hours of March 6, erupting spatter and producing lava flows.

Spatter reaching up to 30 m (100 ft) from a fissure that opened this morning.

Increased activity on one of the new fissures between Pu‘u ‘Ō‘ō Crater and Nāpau.

Ash cloud rising from Pu‘u ‘Ō‘ō as crater floor collapses due to magma withdrawal. Incandescent rubble can be seen crumbling and rolling down the scarp. The east rim of Pu‘u ‘Ō‘ō is in the foreground.

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.

View to the SW at the new fissure eruption between Pu‘u ‘Ō‘ō and Nāpau. Cracks in the foreground could be seen opening as photo was being taken.
