After two years of monitoring, a report has recently been published. The report provides an update of scenarios for mountain slope failures and tsunami inundation maps for Uummannaq and settlements, and it can be downloaded from the link given below.
The new technical report on updated landslide scenarios, tsunami inundation, and risk assessments can be downloaded from here.
Summary of the situation in June 2024
Based on data from the current monitoring within the last month, it can be reported that there is no imminent danger of major rockslides or subsequent dangerous wave inundation at populated areas in the Uummannaq Fjord system. There is still rockfall activity and probability of minor landslides on the unstable mountain slopes mapped in red in figures 2 and 3. Staying close to the mountains is not recommended around these areas.
Monitoring data collected since the beginning of June 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 2 and 3): The blue areas mark registered displacements, while the red color areas indicate locations with multiple rockfalls and minor slide events during June 2024.
As already seen in the recent two months, the observed displacement rates in June 2024 in the monitored mountain slopes have remained lower compared to the end of 2023. In the lower compartments of the unstable slopes in Kangerluarsuk and Umiammakku Nunaat 3, the displacement rates have been observed to accelerate weakly. Increasing temperatures and the unset of thawing on ground may subsequently be followed by increase in displacement rates on the unstable slopes, like the observations in the early summer of 2023.
Due to the upcoming fieldwork for the geologists, there will be no monthly assessments published in August and September. However, if there are any critical changes in the monitored mountain slopes, this will be communicated as soon as possible.
