Multi-Year Satellite Observations of Sulfur Dioxide Gas Emissions and Lava Extrusion at Bagana Volcano, Papua New Guinea B.T
1 Multi-year satellite observations of sulfur dioxide gas emissions and lava extrusion at Bagana volcano, Papua New Guinea B.T. McCormick Kilbride 1;∗, K. Mulina 2, G. Wadge 3, R.W. Johnson 4, I. Itikarai 2, and M. Edmonds 1 1COMET, Department of Earth Sciences, University of Cambridge, Cambridge, UK. 2Rabaul Volcanological Observatory, Rabaul, Papua New Guinea. 3COMET, Department of Meteorology, University of Reading, Reading, UK. 4School of Asia and the Pacific, Australian National University, Canberra, Australia. Correspondence*: Brendan T. McCormick Kilbride, Department of Earth Sciences, University of Cambridge, Downing Street, Cambridge, CB2 3EQ, UK [email protected] 2 ABSTRACT 3 Bagana, arguably the most active volcano in Papua New Guinea, has been in a state of 4 near-continuous eruption for over 150 years, with activity dominated by sluggish extrusion of 5 thick blocky lava flows. If current extrusion rates are representative, the entire edifice may have 6 been constructed in only 300-500 years. Bagana exhibits a remarkably high gas flux to the 7 atmosphere, with persistent sulfur dioxide (SO2) emissions of several thousand tonnes per day. 8 This combination of apparent youth and high outgassing fluxes is considered unusual among 9 persistently active volcanoes worldwide. We have used satellite observations of SO2 emissions 10 and thermal infrared radiant flux to explore the coupling of lava extrusion and gas emission 11 at Bagana. The highest gas emissions (up to 10 kt/day) occur during co-extrusive intervals, 12 suggesting a degree of coupling between lava and gas, but gas emissions remain relatively high 13 (∼2500 t/d) during inter-eruptive pauses. -

Also, there will be Super Science day at the State Planetarium coming up soon. never mind it, but this year it’s bugging me. It’s stopping or delaying many things. Our last meet- ing cancelled (a rarity!), very cold observing Also, we will soon be looking for another round of nights, very cold Outreach nights. But you know nominations for the next Board of Trustees of the club. This needs to be done by the May meeting. We what’s coming? SPRING! March and April bring need a volunteer to lead a nomination committee by chances at Messier Marathons. Maybe we could do one, maybe it won’t snow, or rain, or sleet, or our March meeting.

PACIFIC MANUSCRIPTS BUREAU Room 4201, Coombs Building Research School of Pacific and Asian Studies The Australian National University, Canberra, ACT 0200 Australia Telephone: (612) 6125 2521 Fax: (612) 6125 0198 E-mail: [email protected] Web site: http://rspas.anu.edu.au/pambu Report on PMB field work in East New Britain and Port Moresby, 3-14 May 2009 General. The main aim of this fieldwork was to microfilm remaining unidentified volcanological records at the Rabaul Volcanological Observatory. In addition it was planned to locate and if possible microfilm a journal of the Sacred Heart Missionaries, Hiltruper Monatshefte, in the MSC library at Vunapope. Nine reels of microfilm were made, as follows: PMB 1327 RABAUL VOLCANOLOGICAL OBSERVATORY, Additional volcanological records, 1953-2008. Reels 1-5. (Restricted access.) PMB Doc 500 Hiltruper Monatshefte (Missionaries of the Sacred Heart), Vols.3, 5-10, 12-13, 1886, 1888-1893, 1895-1896. Reels 1-4. (Available for reference.) See Reel Lists at Appendix 1 & 2 for details. The fieldwork was carried out without Kylie Moloney, the PMB Archivist, as I was already familiar with the RVO records and to minimize PMB expenditure. At one stage it was proposed that Karina Taylor, Pacific Archivist in the ANU Archives Program, would join up with me on the Port Moresby leg, as she was planning a visit to the New Guinea Collection at the UPNG Library to initiate a twinning relationship between the two institutions. However the timing did not suit the UPNG staff and Ms Taylor postponed her trip. Rabaul, 4-12 May. The PMB work at the RVO is being carried out in conjunction with the GeoScience Australia- RVO Twinning Project. -
