RT Journal Article T1 Volcano collapse and tsunami generation in the Bismarck Volcanic Arc, Papua New Guinea A1 Silver, Eli A1 Day, Simon A1 Ward, Steve A1 Hoffmann, Gary A1 Llanes Estrada, Pilar A1 Driscoll, Neal A1 Appelgate, Bruce A1 Saunders, Steve AB During a cruise on the R/V Kilo Moana in 2004, we mapped 12 debris avalanches from volcanoes in the Bismarck volcanic arc, estimated their sizes and computed the size of potential tsunami run-up in major local population centers from these features. We used the towed side-scan instrument HAWAII MR1, the hull-mounted EM120 system for swath bathymetry and backscatter intensity, a shallow penetration chirp system, several bottom camera tows and selected cores. We calibrate our computations with the known tsunami run-up of the Ritter collapse. Even the small collapses may have had significant run-up on near-by coastlines. Had any of the collapses we have identified occurred in modern times each would affect a presently populated region of the coastline to a moderate or significant degree.
