New paper with @atterholt.bsky.social, Yan Yang, Ettore Biondi, and Zhongwen Zhan: seismica.library.mcgill.ca/article/view... Coda phases are easily identified on DAS and provide a powerful constraint on structure. We use Ps phases to image a slumped block in Owens Valley, CA at high resolution.

The Reykjanes Peninsula at Iceland's southwestern edge is the country's most volcanically active. In 2024, sensing technology developed at Caltech was deployed in the region to study the motion of subsurface magma & its eruption into lava on the surface. www.caltech.edu/about/news/f...

I don't know if there are any other co-authors on here, but I'd certainly like to thank @atterholt.bsky.social, who was an invaluable collaborator and mentor throughout my first couple years at Caltech. The analysis in this work was largely informed by long conversations with him. Thanks, Jimmy!

New paper in AGU Advances! We constrained models of dike opening in the recent Icelandic eruptions through observations of dv/v on DAS. Thank you to the many co-authors who made it possible, especially my advisor Zhongwen Zhan. agupubs.onlinelibrary.wiley.com/doi/10.1029/...
