Kīlauea Volcano — Thermal Map of Halema`uma`u Crater (June 6, 2018)
This 3D thermal map shows the new geometry of Halema‘uma‘u Crater. Magma in the summit magma chamber has drained over the past month due to Kīlauea's lower East Rift Zone eruption, causing much of the floor and rim of Halema‘uma‘u to drop or collapse. These changes have resulted in a much deeper crater, with rubble covering the floor. The deepest part of the crater is 280 m (920 ft) below the former level of the crater floor.
