Abstract Due to their large mass, ice sheets induce significant stresses in the Earth's crust. Stress release during deglaciation can trigger large-magnitude earthquakes, as indicated by surface faults in northern Europe. Although glacially-induced stresses have been analyzed in northern Europe, they have not yet been analyzed for Greenland. We know that the Greenland Ice Sheet experienced a large melting period in the early Holocene, and so here, we analyze glacially-induced stresses during deglaciation for Greenland for the first time. Instability occurs in southern Greenland, where we use a combined analysis of past sea level indicators and a model of glacially-induced fault reactivation to show that deglaciation of the Greenland Ice Sheet may have caused a large magnitude earthquake or a series of smaller magnitude earthquakes around 10,600 years ago offshore south-western Greenland. The earthquake(s) may have shifted relative sea level observations by several meters. If the earthquake-induced stress release was created during a single event, it could have produced a tsunami in the North Atlantic Ocean with runup heights of up to 7.2 m in the British Isles and up to 7.8 m along Canadian coasts.

全新世早期格陵兰冰块损失可能引发地震和海啸

摘要 由于冰盖质量大，在地壳中会产生显着的应力。正如北欧的地表断层所表明的那样，冰川消融过程中的应力释放会引发大地震。尽管已经在北欧分析了冰川引起的压力，但尚未对格陵兰岛进行分析。我们知道格陵兰冰盖在全新世早期经历了大的融化期，因此在这里，我们首次分析了格陵兰冰川消融过程中冰川引起的应力。不稳定发生在格陵兰岛南部，在那里我们使用对过去海平面指标和冰川诱发断层再激活模型的综合分析来表明格陵兰冰盖的冰川消退可能导致了大地震或一系列较小震级的地震。 10、600 年前格陵兰岛西南部近海。地震可能已经将相对海平面观测值移动了几米。如果地震引起的应力释放是在一次事件中产生的，它可能会在北大西洋产生海啸，海啸在不列颠群岛高达 7.2 m，在加拿大海岸高达 7.8 m。
