Landslide buries over 100 workers at coltan mine in Congo A mudslide has buried more than 100 people in a coltan mine in the east of the Democratic Republic of Congo. The landslide was triggered by heavy rainfall in the early hours of the morning in the town...

There are reports of yet another terrible landslide at the Rubaya coltan mining area in the Democratic Republic of Congo. As always, the losses are unclear, but may well exceed 100 people.

Should have repurposed the blue loop out at the airport.

Cool program, I hasn't heard of that before. Also confidence inspiring to see the results are so similar!

You'll also note that it decorrelates exactly where the scarps or extreme surface deformation are because there are no similar features in the before images.

Thanks for sharing @davepetley.bsky.social!

@theronfinley.bsky.social, Panya, Jan, and I were very fortunate to be able to get to the site to survey the impacts of the earthquake. I'm very grateful for how many "once in a lifetime" opportunities we get up here!

All landslides are mudslides in Canadian media. Some are just muddier and slidier than others.

Alberta officials stalled coal mine pollution study | The Narwhal An Alberta government scientist was prevented from speaking publicly about his coal mine pollution research, emails show

I don't usually do this but if you love nature & quality journalism please donate to The Narwhal. Their work is more important than ever, and are currently trying to raise $200,000 to keep the lights on. You get a charitable receipt, and a donor is matching funds. Please share πŸ§ͺβš’οΈ

This is right above the White River and it actually does look like that. No recorded ascents yet because the eye of Sauron on top is off-putting for would be ascentionists.

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.

This is work from my MSc supervised by @geobrentatlarge.bsky.social and Jeff Bond, heavily revised over the intervening years (lets not count how many) and finally published! Thanks to all the coauthors including @tephrabird.bsky.social, for their contributions and bearing with me over the years.

The 17 december 2024 Takhini River landslide and river-ice tsunami, Whitehorse, Yukon, Canada

Here's an article I wrote on a novel landslide that generated a destructive river-ice tsunami on the Takhini River last winter. Definitely a hazard to consider in cold regions. Thanks to the folks who gave me their thoughts and comments on the paper: Panya, Marten, Hig, and anonymous!

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.

@watershedlab.bsky.social I watched Brent saddle up on this thing several hours earlier and knew it was something I needed to experience myself. 7/10. A bit firm and saddle horn was hard to grip. Also need a steed with a leg length to match mine.
