A. J. Sutton T. Elias 2012 Kīlauea Volcano has one of the longest running volcanic sulfur dioxide (SO₂) emission rate databases on record. Sulfur dioxide emission rates from Kīlauea Volcano were first measured by Stoiber and Malone (1975) and have been measured on a regular basis since 1979 (Elias and Sutton, 2007, and references within). Compilations of SO₂ emission-rate and wind-vector data from 1979 through 2006 are available on the USGS Web site (Elias and others, 1998; Elias and Sutton, 2002; Elias and Sutton, 2007). This report updates the database, documents the changes in data collection and processing methods, and highlights how SO₂ emissions have varied with eruptive activity at Kīlauea Volcano for the interval 2007–2010. application/pdf 10.3133/ofr20121107 en U.S. Geological Survey Sulfur dioxide emission rates from Kilauea Volcano, Hawaii, 2007-2010 reports
