Based on recent data from the monitoring, it can be stated that there is no immediate danger of major rock avalanches or subsequent dangerous waves at the inhabited areas in the Uummannaq Fjord system. However, there is a high rockfall activity and probability of minor rock avalanche events at the unstable rock slopes, indicated in red color in figures 1 and 2. In these areas, it is not advisable to stay in the vicinity of those unstable slopes.
Summary of the situation in February 2024
The monitoring data collected from the beginning of February 2024 documents constant displacements of varying magnitudes at the unstable rock slopes in Umiammakku Nunaat and Kangerluarsuk.
The observed displacements are shown as colored areas on the maps below: The blue areas mark recorded displacements, while the red color areas indicate areas with rockfalls and smaller slide events during February 2024.
In February 2024, the rapid movements continue unchanged in the lower compartment of ‘Umiammakku Nunaat 1’ (See Figure 1). Frequent rock falls during February are also observed.
On the unstable slope in Kangerluarsuk, displacements and daily rock falls continue to be seen in the lower parts of the unstable slopes. It is in these parts, especially in the western part, the changes are most prominent (See Figure 2).
The next assessment will be released on Wednesday 3 April 2024. If unfavorable changes occur in the monitored slopes, an assessment will be published earlier than 3 April 2024.
