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.engjournal articlehttp://dx.doi.org/10.1016/j.jvolgeores.2009.06.013restricted access551.21GeodinámicaSismología (Geología)2507 Geofísica2507.05 Sismología y Prospección Sísmica
