Video of the lava lake in the Halema‘uma‘u crater and photos of a small lava flow erupted from the septum on the east wall of Pu‘u ‘Ō‘ō crater.

Video showing the lava lake in Halema‘uma‘u crater

This video shows a quick video of the lava lake in Halema‘uma‘u crater taken during today's overflight. The lava surface has recently been very shallow, as little as 90 meters (98 yards) below the floor of Halema‘uma‘u crater. When the video was taken, the lava was at a high stand during part of a rise and fall cycle, when very little gas is emitted and views are clear. About seven minutes after the video was taken, violent spattering and gas release occurred from the lake margin, triggering a drop of the lava surface to a low-stand level. The substantial overhang along the north rim of the vent cavity is shown very well by the video. Additionally, the remains of the partially destroyed Halema‘uma‘u Overlook—on the rim of Halema‘uma‘u crater, directly above the vent cavity—can be seen several times during the clip. For scale, the vent cavity is about 150 meters (164 yards) wide.

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 The hole on the right, which is no longer active, was the original east wall vent.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.
