Overview map of Canada with location points of 28,000 landslides symbolized according to 31 landslide types. Background image is a combination of ESRI satellite imagery and hillshade of the NRCan High Resolution Digital Elevation Model (HRDEM).

Overview map of Canada with location points of 28,000 landslides symbolized according to interpreted InSAR-based deformation maps for slow slope movement. Interpretation is preliminary and ongoing. Background image is a combination of ESRI satellite imagery and hillshade of the NRCan High Resolution Digital Elevation Model (HRDEM).

Version 13 of the Preliminary Canadian Landslide Database is available. Highlights include 2,500 new entries and 449 slopes that were likely moving (2016-2024) based on interpretation of NRCan and NASA InSAR-based deformation maps.

Magnitude 6.8 earthquake ten minutes ago along Yukon/Alaska border on the Fairweather Fault. I am guessing this will result in some big landslides. 🧪⚒️

This week I get the chance to present at the Rock Slope and Gravity 2025 (RSG-2025) Conference: Forecasting and Modelling Large Rock Slope Failures in a Changing Mountain Environment. Lots of interesting talks: wp.unil.ch/rsg-2025/pro... It has an option to attend online.

Overlay of InSAR displacement data on top of hillshade view of lidar. A strong displacement concentration corresponds with the geomorphic expression of a landslide.

Natural Resources Canada has released a national scale maps of active deformation processes based on 2017-2024 Sentinel-1 InSAR data. For best results download the images, load them up in your fav GIS software, and watch out many hours will be spent checking out features you always wondered about.

Overview map of Canada with location points of 25,550 landslides symbolized according to 30 landslide types. Background image is a combination of ESRI satellite imagery and hillshade of the NRCan High Resolution Digital Elevation Model (HRDEM)

Overview map of Canada with location points of 25,550 landslides symbolized according to what version of the database they were last modified. It shows that more than half they entries were added or modified in the latest version. Background image is a combination of ESRI satellite imagery and hillshade of the NRCan High Resolution Digital Elevation Model (HRDEM)

Over the last three years, @drewbrayshaw.bsky.social, @geocron.bsky.social, me, and twelve colleagues have been compiling a Preliminary Canadian Landslide Database. Version 12 is now available and contains 25,500 entries.

True colour pre-failure imagery from esri

Not sure, the pre-failure imagery from esri shows small scale instabilities and talus along the runout path. Could be runup, or entrainment, or secondary failures.

July 26, 2022 false colour imagery that has good view of both the source and deposit areas.

The July 26, 2022 imagery has a nice view of the source area

June 26, 2022 false colour Sentinel imagery with no landslide deposit

June 29, 2022 false colour Sentinel imagery with landslide deposit

Sentinel imagery suggest it happened between June 26, 2022 and June 29, 2022

Yes there appears to be a few additional potential landslide features not currently in the SIGÉOM inventory. That landslide layer is part of the provincial surficial geology compilation. Not sure what year it was done and if lidar was available at the time.

Lidar and previous landslide inventory support the statement in the news report that landslides have occurred in the area before.

Nice ones!!!

Hillshade view of the 2021 lidar

Topographic profile along longitudinal section

There is 2021 lidar available from (lidar.gov.bc.ca/pages/downlo...) for that feature. It suggest that the local relief is only ~260m.

Brienz has just been evacuated for the second time. The decision is based, among other things, on thousands of simulations that ETH professor Jordan Aaron has produced using a computer model he developed. In an interview with ETH News, he explains why this model was used.
