For example, this figure from Bodtker et al (2022) shows the position of the Moosehide and Sunnydale landslides above Dawson City.

This figure from the paper shows 2.6 million year old glacial moraines offset across the fault, and a remarkable series of gravel mounds up to 35 m in height, that we interpret as push-up structures, developed over numerous seismic cycles.

But, using the amazing ArcticDEM topographic dataset and drone-based lidar, we were able to map a ~130 km-long series of fault scarps near Dawson City, Yukon.

A thread on this paper! 🧪⚒️

The Tintina fault is a major right-lateral fault, stretching ~1000 km across the Yukon, and having slipped a total of ~430 km in its lifetime. It's generally thought to have been inactive since the Eocene.

Life update: got my PhD! What a journey. I'm especially grateful to my supervisors @faultydata.bsky.social and @earthquakeguy.bsky.social for their support and mentorship along the way. Also huge congrats to @thatfaultguy.bsky.social for graduating as well!

If you work on active faults that are challenging to study due to low strain rates and/or environmental factors such as recently glaciated landscapes or dense vegetation, please consider participating in our session at SSA 2024, April 29-May 3, in Anchorage!

As a mostly onshore geologist, I was really struck by how collaborative ship based research is. Many scientists with complementary interests stuck together for several weeks... it made me want to emulate this with onshore research, which feels very independent/solo by comparison.

Lots of work got done too! 28 OBS instruments deployed, 100s of kms of sub-bottom profiles, and many cores and grabs

Just getting my land legs back after a few weeks at sea deploying OBS instruments and hunting for evidence of paleoseismic events on BC's coast. I think I could get used to ship-based research!
