Based on data from the current monitoring, it can be stated that there is no imminent danger of a major rock avalanche or subsequent dangerous wave run-up in inhabited areas in the Uummannaq Fiord system. There is still rockfall activity and the probability of minor landslides on the unstable mountain slopes mapped in red in figures 1 and 2. Staying close to the mountains is not recommended around these areas.
Summary of the situation in April 2024
Monitoring data collected since the beginning of April 2024 shows constant displacements of varying magnitudes in the unstable mountain areas of Umiammakku Nunaat and Kangerluarsuk.
Observed displacements in the monitored mountain areas are shown as areas marked with colors on the maps below (figures 1 and 2): The blue areas mark registered displacement, while the red color areas indicate locations with multiple rockfalls and minor slide events during April 2024.
As already seen in month of March, the observed displacement rates in April 2024 in the monitored mountain slopes have remained lower compared to the end of 2023, and the frequency of rockfalls and rockslides has also been lower.
In the past few days, air temperatures have been above zero degrees, and the snowmelt has begun. In the long term, increased temperatures could be followed by an increase in displacement rates.
The next assessment of the monitored mountainsides will be published on Wednesday, fifth of June 2024, and earlier if there are unfavourable changes in the monitored mountain slopes.
