Detailed Description
On the north margin of the south sulfur bank, which was exposed during the Kīlauea summit collapse events in 2018, light-colored deposits are evidence of the ongoing alteration from volcanic gas emissions. Near the bottom of the photo, bright yellow sulfur deposits, which are a stark contrast to the darker gray basalt rocks, are further evidence of ongoing gas emissions in the area. USGS photo by K.
