Excited to share our research on active, long-lived upper-plate splay faulting in the Alaska subduction zone. New thermochronologic data reveal the exhumation history in the forearc region and persistent inboard deformation along the Kodiak Shelf Fault. doi.org/10.1016/j.epsl.2024.…
New research in #Geosphere presents the first systematic investigation of paleoearthquake timing along the Western Nepal fault system, a major fault zone that cuts obliquely across the high Himalaya in Nepal.
Our study shows that all trenched faults ruptured during the Holocene, suggesting the potential for complex multifault ruptures and highlighting additional seismic hazards within the upper plate of the Himalayan megathrust, with possible linkages to megathrust earthquakes.

If you're not an Earth scientist, you probably don't understand what this paper is about, starting with the title.
That is normal - and it isn't bad! - scientific results have to be communicated with technical language within the scientific community.

Melgar et al. used HR-GNSS and strong motion data to create kinematic rupture models for the Türkiye earthquake doublet. Their results reveal both sub- and super-shear rupture behavior of these events.

One might think smooth faults are more likely to host supershear earthquakes than rough faults, yet our recent study shows the opposite trend. The key is to understand the initial stress & strength conditions over earthquake cycles.

I liked Zoom so much that for a while I scheduled paper writing sessions with students and collaborators seven days a week, starting at 6:30 am.
On 14 January 2021, Thursday, I was writing papers on Zoom. At ~8 am, the door bell rang. I ignored. It rang again. I opened the door.
I am happy to see our recently published work, part of my PhD dissertation, being selected as a research spotlight by the EOS. A big thanks to Dr. @Sarah_Derouin for writing this report!
[Open Access Paper] How does deep 3D megathrust geometry affect wedge growth, landscape and drainage systems? What is the mechanism of maintaining a plateau along a rapid-erosion edge? Check the example from a topo/tectonic embayment in the Nepal Himalaya. doi.org/10.1029/2021TC007071
A better understanding of the 3D megathrust geometry is important for seismic hazard assessment. The embayment segment is within a seismic gap in large earthquake records. Studies on the 2015 Gorkha earthquake to the east show critical fault-geometry control of earthquake rupture
