Lava spatters above the fissure just west of the base of Pu'u 'O 'o.

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

A small fissure eruption between Pu'u 'O 'o Crater and Napau, extending 100 m long (330 ft) and spattering 20 m (66 ft) high.

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

This fissure is erupting 1.5 km (0.9 mi) west of Pu'u 'O 'o Crater. You can view this eruption on the new Pu'u 'O 'o to Napau Crater webcam.

A close-up of the fissure just west of Pu'u 'O 'o Crater. Spatter was reaching heights of 40 m (130 ft).

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 (March 6).

Increased activity on one of the new fissures between Pu'u 'O 'o Crater and Napau.

Early morning view of the fissure eruption between Napau Crater and Pu'u 'O 'o. 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.

HVO geologist carries a freshly quenched lava sample from the 2011 Kamoamoa fissure eruption on Kīlauea Volcano. Molten lava is quickly placed in a bucket of water to "freeze" the growth of minerals for chemical and microscopic analyses.

HVO gas geochemist uses a Fourier transform infrared (FTIR) spectrometer to measure volcanic gas compositions emitted during the 2011 Kamoamoa fissure eruption on the East Rift Zone of Kīlauea Volcano. The instrument measures the infrared energy from the hot lava fissure as it passes through, and is absorbed by, the volcanic plume along an open atmospheric path.

Lava spatters above the fissure just west of the base of Pu‘u ‘Ō‘ō on March 6, 2011.

Ash cloud rising from Pu'u 'O 'o 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 'O 'o is in the foreground.

View looking at the NE end of the actively propagating fissure. Lava is just breaking the surface in foreground crack.

Incandescent rubble rolling and sliding down the scarp on the edge of the collapsing crater in Pu'u 'O 'o. 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 'O 'o is in the foreground.
