The crater floor at Pu‘u ‘Ō‘ō has recently experienced minor uplift due to inflation within Pu‘u ‘Ō‘ō cone. The crater floor uplift is subtle, and probably no more than about 1 meter (3 feet) since May 15. Small, hot cracks have appeared on the crater floor during the uplift. Time-lapse images from a thermal
camera were used to make this video, which is looped 10 times to highlight the uplift.
