Endogenous crater floor uplift during 2022. A, B) Images from the B1cam webcam spanning April to October, showing the intact rise of the crater floor by approximately 50 m. The majority of this rise was from lava emplaced beneath the surface, akin to inflating an air mattress, with only a minor amount of lava emplaced on top of the crater floor. C) The surface of the lava lake tracked by the continuous laser rangefinder, which closely tracked the height of the solidified crater floor surrounding the lake. Timelapse camera images show that the lake rose with the crater floor
