Spot the drone 👀 Our third visit to Quesnel BC where we’ve been mapping deformation of the aptly-named “Big Slide” using drone lidar. Last year, you could walk along that road! Expert piloting skills by @thatfaultguy.bsky.social
Photo from the top of a large landslide, where part of a road has fallen away. A tiny drone is (barely) visible in the sky above. Lots of fall foliage and Fraser River in the distance

I’d have liked to see more density in neighbourhoods close to the ocean, rather than leaving our amazing sea views to the multi millionaires. e.g. Cadboro Bay which unlike my neighbourhood has buses, shops, and is walkable to UVic.

Well please reconsider changes along Cedar Hill X and Maplewood anyway. CHX has no bus route or even bike lane so how it can fit apartments on either side is beyond me. Those living there will still be 15 mins from nearest shops on McKenzie so it’ll be no less walkable, just ever more traffic.

Dean, for those of us in SFHs marked for rezoning as apartments, how will you prevent us dealing with crippling increases in property tax as our land value rises? It is going to price us out of our own homes, whose actual resale value will therefore drop. The QMP is much too much, too quickly!

This mornings M3.0 felt earthquake near Duncan was well recorded on the #SchoolShake network. No damages expected, but a great reminder to be prepared.

Why are "nation building projects" always things that accelerate the destruction of the planet largely to the benefit of multinational corporations, and never things that would benefit millions of Canadians like, say, high speed passenger rail?

Don’t disagree (and Siamese Dream is one of my all time favourite albums) but Billy Corgan is unfortunately a bit of a twat which slightly spoils it for me

Felt earthquake in the Juan de Fuca straight just south of Victoria! This was felt across the CRD and in Washington State. No damage expected, but another reminder we live in earthquake country.

Yesterday afternoon we finished the final #Ocean Bottom #Seismometer recoveries for #PACSAFE2025, and started redeploying along the Explorer Plate! Here’s a look at our “full house”, with 23 instruments on deck.

#ScienceAtSea #Fieldwork @seos-uvic.bsky.social @eoas.ubc.ca @dalhousieu.bsky.social
Aft deck of a research ship, with many large blue steel stillage crates containing yellow circular ocean bottom seismometers. It is sunny, and one adult man stands on deck looking at the instruments. A rainbow over the ocean, as seen from a research ship off the west coast of Canada.

Another active fault on Vancouver Island - our new paper documents evidence for at least 3 Holocene earthquakes on the Beaufort Range fault
weareseismica.bsky.social
🌍The Beaufort Range fault is ACTIVE!
This right-lateral oblique Beaufort Range faulting occurs >100 km farther North than previously documented faults in the Cascadia forearc.

Sawyer Island located in the middle of Tracy Arm, 7 km downstream the landslide, shown here before and after the estimated 30-m high tsunami! 🌊😱

The isolated tree was particularly resilient! 🌲💪

Wow, it’s nauseating just looking at the video! Hope you’re all coping. Feeling autumnal here in Victoria with the first sustained rain in many weeks, so not surprised it’s rough where you are 🤢

That looked entertaining! Fellow Sky Blue BlueSkyer here btw

Alaska Earthquake Center posted a nice explainer video with some of the video reconnaissance following the recent #landslide and #tsunami in Tracy Arm, south of Juneau, Alaska. It’s a whopper! 🧪⚒️
