How long will the Halema`uma`u vent emit high levels of SO2?
Kīlauea is one of the best-studied volcanoes on Earth, but there’s still much about it that is not known. The current eruptive activity at Kīlauea ‘s summit is a prime example. One HVO scientist described efforts to unravel the mystery of the summit vent as being “perched on Pele’s roof, trying to understand what is going on inside the house by watching smoke rise from the chimney and listening very carefully to the sounds coming from within.” While scientists are trying to determine the specific volcanic processes causing the copious release of gases from Halema`uma`u Crater’s new vent, Hawai`i Island residents and visitors are asking, “How long will it last?” To predict future behavior of active volcanoes, we often look to the past. The first written accounts of Halema`uma`u were recorded by William Ellis when he trekked to Kīlauea ‘s summit in 1823. Since that time, records show that Halema`uma`u eruptions have ranged in duration from over a century to less than day. Thus, the curre
