Lava lake draining event during Pu‘u ‘Ō‘ō refilling

(July 5, 2007, 23:00:06 to July 6, 2007, 09:00:06) With the resumption of eruptive activity at Pu‘u ‘Ō‘ō on July 1, 2007 (Episode 57), a lava lake, fed by two vents, quickly began to form within the Pu‘u ‘Ō‘ō crater. The vent seen here was located on the eastern side of the crater. The other vent, out of sight to the left, was located on the west-central part of the crater floor. Several times during the early part of the refilling process, lava stopped erupting and the lava lake partly drained back into the vent. Moments later, lava re-emerged as the eruption resumed. This movie shows one of these draining events, followed by a smaller secondary draining, during the night of July 5–6, 2007. The images that make up this movie were acquired by a time-lapse camera positioned on the northwest edge of the Pu‘u ‘Ō‘ō crater, about 190 meters from the erupting vent. The camera was later lost when the crater floor and a portion of the crater rim collapsed following the onset of Episode 58 on July 21, 2007.
