  abstract = {{C}limate change is increasingly predisposing polar regions to large landslides. {T}sunamigenic landslides have occurred recently in {G}reenland ({K}alaallit {N}unaat), but none have been reported from the eastern fjords. {I}n {S}eptember 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 {E}ast {G}reenland. {I}n this study, we demonstrate how this event started with a glacial thinning-induced rock-ice avalanche of 25 x 10(6) cubic meters plunging into {D}ickson {F}jord, triggering a 200-meter-high tsunami. {S}imulations 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. {A}n oscillating, fjord-transverse single force with a maximum amplitude of 5 x 10(11) 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. {O}ur findings highlight how climate change is causing cascading, hazardous feedbacks between the cryosphere, hydrosphere, and lithosphere.},
