A new fissure eruption in September 2011 on the east flank of Pu‘u ‘Ō‘ō on Kīlauea Volcano's east rift zone reminds us of the need to be aware of our ever-changing volcanic environment on Hawai‘i Island. The fissure—the source of the lava flow—is shown in this image. Pu‘u ‘Ō‘ō cone and crater are in the background. Aerial view is to the southwest.

The western Kamoamoa fountain-fed lava flows advanced over 1997 lavas (dark flow in foreground) with 1965 and 1968 lavas buried by Pu‘u ‘Ō‘ō cinder to the far left. Pu‘u ‘Ō‘ō is in the distant background.

After an intrusion on March 5, Pu‘u‘ō‘ō crater floor subsided for several hours. Hot incandescent crater walls were exposed as the floor dropped a total of 113 m (371 ft). Frequent rockfalls into the crater triggered red ash plumes. USGS photo taken by T. Orr on March 5, 2011, at 4:32 p.m.

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.

Scientists collect volcanic gas data using a Fourier Transform Infrared spectrometer (FTIR). During the Kamoamoa eruption, sulfur dioxide emission rates from Kīlauea’s East Rift Zone reached the highest levels since the episodes of high-fountaining at Pu‘u‘ō‘ō (1983–1986) with an average rate of 8,500 tonnes per day and a peak value of 11,000 tonnes per day.
