This 3D model of the Pu‘u ‘Ō‘ō crater was constructed from thermal images taken during a recent helicopter overflight. White areas show warm spots in the crater. Despite the absence of active lava in Pu‘u ‘Ō‘ō, changes at the crater have continued since magma drained from beneath it on April 30, 2018. The shape of the crater continues to change through occasional small collapses within it. The crater is now roughly 290 m (950 ft) deep.
