showing timelapse sequence from Pu‘u ‘Ō‘ō

Preview image for video: shows a timelapse sequence taken from a thermal camera on the rim of Pu‘u ‘Ō‘ō crater. The movie spans from May 26 to today and shows the rising level of the lava lake in the crater. In the first part of the movie, covering most of June, the level of the lava lake rises primarily due to overflows building the steep levee walls higher. In the last portion of the movie, from about July 1 to today, much of the rise of the lava lake has been due to uplift of the crater floor, carrying the lava lake upward. This uplift has been especially pronounced over the past few days, shown by the final few moments of the movie. The temperature scale is in degrees Celsius.
