Subtle uplift of Pu‘u ‘Ō‘ō Crater floor over past few days

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.
