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 March 2024
Monitoring data collected since the beginning of March 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 dispacement, while the red color areas indicate locations with multiple rockfalls and minor slide events during March 2024.
Observed displacement velocities have recently been generally lower in the monitored mountainsides compared to the end of 2023. In several locations, the registered average velocity has been halved.
The deformation camera in Kangerluarsuk went out of service on March 10, 2024, but in cooperation with Municipality of Avannaa and two locals from Ukkusissat, the camera has come to function again on March 28. We thank everyone involved for their work.
The next assessment of the monitored mountainsides will be published on Wednesday, first of May 2024, and earlier if there are unfavorable changes in the monitored mountain slopes.
