Collapse and refilling of Pu‘u ‘Ō‘ō crater

(June 10 to July 25, 2007) During June 17–19, 2007, an intrusion into Kīlauea's upper east rift zone (Episode 56) led to the cessation of eruptive activity at Pu‘u ‘Ō‘ō and the collapse of the Pu‘u ‘Ō‘ō crater floor (Poland and others, 2008). The quiet did not last long, though, and lava began to erupt on the floor of the Pu‘u ‘Ō‘ō crater in early July (Episode 57). After several days of slow filling, the crater began to uplift as pressure increased below. Then, just after midnight on July 21, 2007, a new fissure eruption (Episode 58) broke out on the eastern flank of the Pu‘u ‘Ō‘ō cone (Poland and others, 2008) and Pu‘u ‘Ō‘ō's crater floor collapsed again. This movie shows these events by compiling one image per day for the period June 10 to July 25. The images that make up this movie were acquired by a pan-tilt-zoom Webcam positioned on the north rim of the Pu‘u ‘Ō‘ō crater. The Webcam captured a series of three adjacent images spanning the width of the crater with a repeat interval of 1 minute. For this movie, a single set of three images, acquired roughly at midday and with good visibility, was selected from each day for the period June 10 to July 25.
