Bird, et al. use Ps converted phases observed on an optical fiber to image fine-scale structures in Owens Valley, CA. 🔗 Read now: seismica.library.mcgill.ca/article/view... @elibird.bsky.social @atterholt.bsky.social

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...

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/...
