New research documents active upper-plate normal faulting on Chirikof Island in the Alaska subduction zone, revealing a recent shift from long-term shortening to extension in the forearc. #GSAPubs @gsapublications doi.org/10.1130/G54733.1

Chirikof lies between two segments that exhibit contrasting upper-plate deformation and megathrust behavior. Subducting-plate structures have long been proposed to influence megathrust behavior. They may also control along-strike changes in long-term upper-plate deformation.

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.

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.…

Good afternoon Southern CA. Did you feel the magnitude 5.1
earthquake about 4 miles southeast of Ojai at 2:41 pm. #ShakeAlert system was activated. See: earthquake.usgs.gov/earthqua… @Cal_OES @CalConservation @CAGeoSurvey

We published a paper on formation of the Namcha Barwa Syntaxis in Tibet. Erosion-driven diapirism can cause positive feedback between erosion and rock uplift.

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.

What is the most sensible way to compare distributions like detrital mineral ages and grainsizes?
Pieter Vermeesch and I think we have an answer... read our 🚨💥new preprint 💥🚨 to find out!

NASA #astronaut Jessica Watkins recently had a 📔 paper about space published while she was in space, on a 🚀 mission to the @Space_Station, @howellspace writes for @SPACEdotcom. See the @astro_watkins paper in JGR: Planets. #AGUintheNews #AGUpubs

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!
Understanding the nature of the megathrust in the western Nepal Himalayas is crucial when determining the seismic hazards in the region.

[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
Many thanks to Michael Murphy (advisor), David Whipp @dave_whipp (c), Joel Saylor (c), Peter Copeland (c), Andrew Hoxey, Michael Taylor (c), and Daniel Stockli for their contribution and mentorship (c-committee). Picture: View of the embayment/study area from space (source: NASA)
