- Lava lake activity at Pu'u 'O'o crater in July 2007, Part 3: the lava lake in the eastern half of Pu'u 'O'o -


View of the partly drained lava lake in Pu'u 'O'o crater. Originally, the lake had occupied the entire bottom of the collapsed crater and had been fed from two vents, one in the center of the crater (near the background of the photo) and one in the north-eastern part of it (center-right of the photo). Now, only the eastern vent is still active and the lava lake has drained and receded within a 2-m high levee, assuming a 8-shaped surface.		Volcanic gas escaping from the crater.	View onto the largely crusted over lake.

Sequence of photos showing the occasional overturning of the thin crust. The photos are spaced only few seconds apart from each other and show how the crust breaks into roughly concentric segments that overturn domino-style progressively from the inside out.

The lake at night.	Three days later, on July 17, the lake is no longer active.	On July 18, some lava flows emerge again from the East vent and cover the area of the lava lake.	On July 20, most activity in Pu'u 'O'o takes place in the central and western areas, while the eastern part (foreground) has only a few small active flows. A day later, all activity in Pu'u 'O'o ends suddenly...
