Our new paper is out in @FrontEarthSci, led by the incredible Line Rouyet @NORCEresearch. This details the use of #insar for slope movement inventory mapping and velocity categorisation. Fairly complex process but lovely results!

Another powerful before-vs-after shot of #Hwy8 near #MerrittBC. The road is gone -- and what was once a gentle slope has turned into a steep cliff that drops directly into the river. Image courtesy of Shackan Indian Band. #bcstorms #bcfloods @GlobalBC

Friday Sergio Sepulveda and I examined landslides along some of the highway corridors. We are both at SFU @SFUEarthScience and @CNHR_SFU. We were focused on getting photogrammetry of landslides and evaluating initiation zones. This thread is mainly about landslides. 1/n

Before and after images from @Planet indicate that the 29 October 2021 Kameng Valley event was a probably a rock and ice avalanche that originated on a steep slope high in the mountains:

@davepetley Perhaps they would like to double-down on their claim, and include this Indian-led highway project in Bhutan

An Indian government official claimed yesterday that the Char Dham highway project in India is not responsible for causing landslides. This is demonstrably incorrect:- Images by Hemant Dhyani and Ayush Joshi

I wonder how busy the #PNWstorm and the #BCStorm are going to make things for @davepetley : #Coquihalla , slides over I-5 in Whatcom County, and the 11 miles (really?!) of US101 damaged on the Olympic Peninsula. I've seen images of all, but haven't found a consice compilation.

The #mining sector needs to account for these extreme weather events in managing tailings storage facilities and water pollution. These type of extremes need to be part of every BC Environmental Assessment and permitting, and potentially denying approval based on safety. #bcpoli

I’m staring at this numbers and it’s just as jarring for me personally as the heat dome temperatures in June. #BCFlood #BCstorm
