Yeah I meant taking the burden off grad students who have enough on their plate. Agree that senior PhDs should be reviewing too though

The lack of obvious internal deformation *within* the landslide is amazing. Must be a very simple failure plane?

This is great. That orange crosswalk is ^so^ dangerous. I once saw a driver blast through while a pedestrian was mid way across, missing causing a fatality by inches.

B.C. has seen a lake tsunami before — and it could happen again | CBC News In 2007, a massive landslide crashed into B.C.'s Lake Chehalis, triggering a tsunami that surged 38 metres up the shore — one of the most dramatic inland waves ever recorded. CBC’s Johanna Wagstaffe l...

Exciting to see lake tsunami research in the spotlight! I joined CBC to talk about our work at Chehalis Lake and how we can go about better understanding lake tsunami hazard here in BC. #Geohazards #LakeTsunami #ScienceCommunication

One of my favourite trivia questions is how many (or which) countries Canada shares a land border with. Maybe it’ll be more than two soon, given the damage being done to the union…
