New 3D Model of the Halema‘uma‘u Crater Summit Lava Lake (May 8, 2018)

The summit lava lake in Halema‘uma‘u crater has dropped substantially over the past week due to intrusive and eruptive activity on the lower East Rift zone. This 3D model of the crater was created from thermal images collected during a helicopter overflight on May 8. The lake at this time was roughly 295 m (970 feet) below the floor of Halema‘uma‘u Crater.
