Excited to share the first paper from my Phd work! Here- pubs.geoscienceworld.org/gsa/gsabulle... we show oscillating folding behavior at the Syrian Arc, an interesting case of intraplate inversion structures developing in a subducting plate, far away from the subduction zone.
High-resolution reconstruction of folding history in the central Syrian Arc fold system reveals episodic shortening | GSA Bulletin | GeoScienceWorld
Intraplate shortening of the northern African passive margins has been widely observed, but the history of shortening and thus the underlying processes

Published!!!! The first article of my PhD and the first from the lab that I set up!! 🤩🤩
We study the dynamic effects of fault bends on earthquake ruptures by imaging shear ruptures in PMMA plates propagating through bends (double bends to be exact).

Lab earthquakes reveal a wide range of rupture behaviors controlled by fault bends | PNAS
Natural faults are typically nonplanar and exhibit multiple bends, which deviate from
the general fault orientation at different angles. However, w...

🧵 1/3 Very excited to share here our new publication in PNAS! We reveal how drainage divides don't migrate steadily but in intermittent pulses, likely linked to paleoclimate shifts 🌍

If you ever did geology in the Levent region, the Syrian Arc is a core concept you were presented as THE major tectonic element of the region for the last ~80 Myr (that and the much younger Dead Sea Transform). But with new data, that model is being challenged. ⚒️🧪
