Recently while out exploring my husband pointed out this fault exposed in the cliffside. Today he showed me a picture of something he saw whole working, using a banana for scale. He said he's learned to always use a scale from me. I think I've actually turned him into a geologist 😅 #geology 🧪 🛠️

This review paper is a fascinating read for those interested in land surface hazard cascades.

A textbook example of how strike slip faults can partially or even fully 'behead' smaller channels. This often forms a characteristic deflection reach along the fault, and sometimes even spurs an avulsion. Amazing footage indeed, but my heart aches for those affected.

Our blog has been a bit quiet over these winter months, but I have added a new article describing our recent trip to Morocco, working with scientists from Mohammed V University in Rabat to understand more about earthquake sources around the Atlas mountains. quakesincentralasia.org/research-upd...

In 2016 the Papatea fault ruptured, where ~6.5m of fault uplift diverted the river into a new course, scouring out this ~250-400 m wide avulsion channel (footage taken in 2021). Note the white truck sitting on top of the Papatea fault scarp for scale. 🧪 #geology #geomorphology #womeninSTEM

@paleoseismicity.bsky.social has been kind enough to publish a short blog post outlining some of the key points from our most recent paper on Coseismic River Response. Check it out if you are interested 😁

10 years ago I thought I wasn't smart enough to study #geology, but some colleagues convinced me to try anyway. Today I just published my 2nd paper, which explores how fault ruptures can alter river behaviour and flood hazard. Check it out here! www.sciencedirect.com/science/arti...

Bottom: three block diagrams illustrating how faults can interact with river channels by creating a dam, shifting them laterally, or tilting the channel in retrograde.

This picture of me finding a crab fossil is a good representation of what my face looked like this morning after finding out my 2nd paper has been accepted. Very happy 😁 #geology #womeninSTEM

I decided to leave no stone unturned and make my own #geology themed birthday cake this year. I think it turned out pretty gneiss? All components are 100% edible, so the guests could literally lick rocks if they wanted 😅

The best part of this are the comments. Absolute gold 😅

I couldn't not take a photo of this beautiful stratigraphy while assisting with a fieldtrip out in Castle Hill Basin earlier this year. What a story this outcrop has to tell ❤️ #geology #earthscience #womeninSTEM #fieldwork

For today's (somewhat late) #Fridayfold, I'm going smaller in scale. Here are some beautiful soft sediment deformation structures I spotted when exploring the Oamaru volcanic field #geology #earthscience #womeninSTEM

This unassuming river terrace is actually the Kekerengu fault. In 2016, ~2.5 m of fault throw uplifted a large section of the Waiau Toa /Clarence riverbed, exposing the underlying bedrock and this beautiful erosion surface. Geomorphology in action! #geomorphology #earthscience #geology #womeninSTEM

It's Friday fold time! Earlier in the year some of our dept completed a rafting trip down the beautiful Waiau Toa / Clarence River, where we were treated to these beautiful chevron fold outcrops. Very cool! #foldfriday #geoscience #womeninSTEM

Throwback to one of the coolest moments of my life - standing on the Alpine Fault plate boundary. The minty green cataclasite is the Pacific Plate, where it is overriding the brownish quarternary gravels of the Australian Plate. Absolutely amazing ❤️ #geology #tectonics #geoscience #womeninSTEM

Love this! Such a fun idea 😁
