Events at the summit of Kīlauea over the past few weeks have dramatically reshaped Halema‘uma‘u, shown here in this aerial view, which looks west across the crater. The obvious flat surface (photo center) is the former Halema‘uma‘u crater floor, which has subsided at least 100 m (about 300 ft) during the past couple weeks. Ground cracks circumferential to the crater rim can be seen cutting across the parking lot (left) for the former Halema‘uma‘u visitor overlook (closed since 2008). The deepest part of Halema‘uma‘u (foreground) is now about 300 m (1,000 ft) below the crater rim. The Halema‘uma‘u crater rim and walls continue to slump inward and downward with ongoing subsidence at Kīlauea's summit.
