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.
Imaging the North Bishop Block with Ambient Noise and Converted Phases Observed through Fiber-Optic Seismology
Located in eastern California, Owens Valley is a rift basin in the western Basin and Range Province, bounded by the Sierra Nevada and White Mountains. While the basin has been the site of extensive ge...

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.

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.

Constraining Dike Opening Models With Seismic Velocity Changes Associated With the 2023–2024 Eruption Sequence on the Reykjanes Peninsula
Subsurface deformation associated with the 2023–2024 eruption sequence on the Reykjanes Peninsula produces a pronounced dv/v signal The observed dv/v signal is inverted for a model of dike-openin...
