In my new paper I actually documented more CRR events in single-thread rivers. Potentially because the features of a CRR are better preserved in those environments. However unconfined braided systems are vulnerable to rapid avulsion as they have quite erodible substrates.

These are some LINZ images from around 2015 (left) and 2022 (right) which nicely illustrate the main avulsion node. Further down, the fault actually impounded the river a 2nd time, forming a lake! If you want to know more I have a paper on this area here: www.science.org/doi/10.1126/... 🙂

Drone footage credit goes to Regine Morgenstern of GNS science. And of course @aotearoa-unzpd.bsky.social who arranged this awesome field excursion back when I first started looking into the topic of fault-induced induced river avulsion.

Stunning! 😍

Hi Mae, can I please be added to this list? I've just listed a couple of publication links below for reference. Also thanks for curating this feed, it must be a busy job!

Coseismic river avulsion on surface rupturing faults: Assessing earthquake-induced flood hazard
Fault rupture-induced floods can be modelled before earthquakes, which helps mitigate risk associated with this coseismic hazard.

An extra big thank you to the awesome co-authors, supervisors, and reviewers who helped get the manuscript across the line. You all rock! #academicsky #womeninSTEM #geology

They are candy coated chocolate. I found them through a local business that imports all sorts of sweets 🙂

Personally I'm a big fan of the random directional arrows. Unsure what direction the river is flowing? Just have your arrow pointing in both directions - problem solved!

The whiter units are part of the Coleridge formation, which is largely a massive quartz sandstone interspersed with beds of limestone. So, mostly sandy 🙂
