I takt med at undergrunden er i f\u00e6rd at fryse til, kan man dog observere en svag opbremsning mod slutningen af december m\u00e5ned.<\/p>\n<p>I Kangerluarsuk er der fortsat konstante forskydningsbev\u00e6gelser i de ustabile fjeldpartier, men disse er markant mindre end bev\u00e6gelserne i Umiammakku Nunaat omr\u00e5det.

De st\u00f8rste bev\u00e6gelser er registreret i de nederste omr\u00e5der, hvor bev\u00e6gelserne var for hurtige til at kunne registreres over hele \u00e5ret. I l\u00f8bet af sommerm\u00e5nederne er der registreret op til 1 meter forskydning per dag i disse omr\u00e5der.<\/li>\n<li>Umiammakku 1 og 2: De hurtigste forskydninger observeres i den nederste del af Umiammakku 1, som sk\u00f8nnes at v\u00e6re p\u00e5 omkring 100 m (Figur 4). Det \u00f8verste del af Umiammakku 1 har gennemsnitlige forskydninger p\u00e5 omtrent 1 meter, ligesom det vestlige omr\u00e5de af Umiammakku 2. Ved Umiammakku 2 observeres delvis store forskydninger i fjeldskredsaflejringerne fra 2017.
