Tsunamigenic landslides have occurred recently in Greenland (<i>Kalaallit Nunaat</i>), but none have been reported from the eastern fjords. In September 2023, we detected the start of a 9-day-long, global 10.88-millihertz (92-second) monochromatic very-long-period (VLP) seismic signal, originating from East Greenland. In this study, we demonstrate how this event started with a glacial thinning–induced rock-ice avalanche of 25 × 10<sup>6</sup> cubic meters plunging into Dickson Fjord, triggering a 200-meter-high tsunami. Simulations show that the tsunami stabilized into a 7-meter-high long-duration seiche with a frequency (11.45 millihertz) and slow amplitude decay that were nearly identical to the seismic signal. An oscillating, fjord-transverse single force with a maximum amplitude of 5 × 10<sup>11</sup> newtons reproduced the seismic amplitudes and their radiation pattern relative to the fjord, demonstrating how a seiche directly caused the 9-day-long seismic signal. Our findings highlight how climate change is causing cascading, hazardous feedbacks between the cryosphere, hydrosphere, and lithosphere.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A rockslide-generated tsunami in a Greenland fjord rang Earth for 9 days","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-18 01:32:45.195582","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"FREE OSCILLATIONS;SEISMIC SIGNALS;MOUNT-PINATUBO;KARRAT FJORD;LANDSLIDE;MODEL;RAYLEIGH;WAVES;SEICHE;MASS","OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2025-09-18","DateCreate":"2024-09-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001408428800029","VABBcode":null,"OpenAcc":1,"DOI":"10.1126/science.adm9247"},"refs":null,"anarec":{"AnaID":395643,"PubliDate":2024,"Pagination":"1196-1205","XtraPublOfAnaID":null,"ISBN":null,"Volume":"385","Issue":"6714","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43776,"SerRR":"Science (Washington).
