Looking down into the vent cavity of the Halema‘uma‘u Overlook vent. The black ring on the walls surrounding the lava pond is a high lava mark, outlining the height the lava rose during a recent rise/fall cycle.

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

Photo of vigorous boiling of the lava surface in Kīlauea's summit vent following vent wall and rim collapses earlier in the day. The rim of the vent on the floor of Halema‘uma‘u is about 150 m (yards) across. The lava surface is about 100 m (yards) below the rim.

Lava began erupting from the septum between the two openings on the east wall of Pu‘u ‘Ō‘ō crater the morning of February 17, just after 7:00 am.

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.

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.

Breakouts remain active near Kalapana, with vigorous activity situated approximately 630 meters (0.4 miles) west of the end of the Kalapana access road. This breakout, just south of a partially burned kipuka, was cascading into a small depression on the flow field.
