Explosive Collapse Event at Kīlauea Releases Energy Equivalent to 5.4 Earthquake

SO2 camera removed from HVO’s summit: For several years, a special ultraviolet camera has been located near Keanakākoʻi Crater at Kīlauea’s summit. The camera was capable of detecting SO2 gas coming from Halema‘uma‘u crater. This morning, the camera was removed because there is very little SO2 to measure these days at the summit. In addition, cracking near Keanakākoʻi Crater was making access difficult.
