small amounts of sulfur dioxide

Only small amounts of sulfur dioxide (SO2) and hydrogen sulfide (H2S) are currently being released from Kīlauea, but they chemically react with each other (oxidation-reduction reaction) to form the bright yellow sulfur deposits visible on the crater walls within Halema‘uma‘u. The current low sulfur emission rates at Kīlauea have contributed to

The prolonged yet dramatic partial collapse of Kīlauea caldera this past summer was the first to be observed in detail and the largest measured by subsidence volume of more than a dozen summit collapses in the past 200 years. The earliest known collapses (1823, 1832, and 1840) were large in subsidence volume but the process was not recorded by witnesses.
