A small lava flow erupted from the septum between two vents on the east wall of Pu‘u ‘Ō‘ō crater on Sunday, February 6. The hole on the right, which is no longer active, was the original east wall vent. The fuming hole behind the new lava flow is the current east wall vent.

This week, the northwest vent was producing lava flows on the floor of Pu‘u ‘Ō‘ō crater. The northeast cone is in the background, as well as the small lava flow that ran down the east wall of the crater.

A new rootless shield is building along the TEB tube above the pali. Lava began erupting in the area on February 4, and has built up a shield and lava pond about 10 m (33 ft) high.

A view looking south at this morning's new breakout. The southern opening is completely filled in and the flows are expanding across the crater floor. The geologist on the opposite rim is 1.8 m (6 feet) tall.

At the same time the vent on the east wall was erupting, a small lava pond fed by the northeast vent began to overturn.

The northeast vent on the floor of Pu‘u ‘Ō‘ō is once again producing lava flows that are repaving portions of the crater floor. The fuming area on the back wall is the main source of last week's activity in the crater.

Overflows from the lava pond in Pu‘u ‘Ō‘ō have nearly leveled the crater floor with the perched pond. The floor of the crater is now 39 m (128 ft) below the east rim.

Numerous spattering sources were active on the east end of the pond, causing pond level fluctuations throughout the day.

Aerial view of Pu‘u ‘Ō‘ō crater, looking north-northeast. New flows, erupting from a spatter cone just above the center of the photo and a spatter cone to the left of center, have been slowly filling the crater over the past few months.

Viewing looking northeast across Pu‘u ‘Ō‘ō crater. The spatter cone erupting lava flows on to the crater floor over the past few weeks, visible just above the center of the photo, tops the low mound of lava that it has constructed.

View looking north at the spatter cone on the northwest side of Pu‘u ‘Ō‘ō crater floor. The cone is about 6 m (20 ft) high.
