Map showing Pu‘u ‘Ō‘ō and the extent of nearby lava flows. The currently active flow (episode 61) is shown as the two shades of red—pink is the extent of the flow from September 21 to November 21, and bright red marks flow expansion from November 21 to December 2. The contour interval on Pu‘u ‘Ō‘ō is 5 m.

This photograph, taken from the east rim of Pu‘u ‘Ō‘ō crater, shows a cone in the crater which was occasionally spitting minor amounts of spatter from the incandescent opening at its top.

Active pāhoehoe, fed by a lava tube originating at Pu‘u ‘Ō‘ō, has been migrating downslope within the Royal Gardens subdivision over the past week. The flow front is outlined by the white dotted line. The flow is running alongside a forested kipuka, triggering brush fires visible in the photo.

The currently active flow (episode 61) is shown as the two shades of red—pink is the extent of the flow from September 21 to November 10, and bright red marks flow expansion from November 10 to November 21. The contour interval on Pu‘u ‘Ō‘ō is 5 m.

For a brief period this afternoon a vigorously spattering vent at the east end of Pu‘u ‘Ō‘ō crater fed a swiftly moving river of lava that cascaded into the deeper portions of the crater. The cascade was over within about ten minutes of this photograph, but the vent continued to spatter.

A collapse of a thin portion of the roof over the lava tube reveals the lava stream beneath the surface. The fluid stream is the bright orange color, with the dark orange area to the left representing the hot, incandescent tube wall. The lava stream today was relatively slow moving in the tube, perhaps reflecting a low rate of lava supply to the flow front.

This photograph, looking east, shows a large skylight on the lava tube that is supplying lava to surface flows north of Royal Gardens subdivision. The tube trace, which heads southeast, is marked by the line of fume sources in the upper right portion of the image.

A close-up view of the skylight. The flowing lava stream in the tube was easily visible.

Photo of the lava lake within the vent inset within the east wall and floor of Halema‘uma‘u Crater on March 3, 2011, just days before the Kamoamoa fissure eruption caused the lake level to drop much deeper and out of sight.

Map showing Pu‘u ‘Ō‘ō and the extent of nearby lava flows. The flows of the currently active episode 61 east flank phase (September 21-ongoing) are the two shades of red—pink is the extent of the flow from September 21 to October 25, and bright red marks flow expansion from October 25 to November 3. The trace of the tube carrying lava downslope is shown in yellow.

View looking northwest through rain at the silvery flows at the front of the active episode 61 flow field. Pu‘u ‘Ō‘ō is hidden in the clouds in the top left part of the photo. The ‘A‘ā flow at bottom center is the inactive terminus of the initial flow emplaced on September 21-22, 2011, after the episode 61 fissure on Pu‘u ‘Ō‘ō's east flank opened on September 21.
