New paper in Science! We used a fiber-optic array to tackle the tricky problem of imaging an offshore earthquake (2024 M7 Mendocino Fault EQ). In the process, we learned new things about supershear transitions and how fiber arrays could help with EEW. Read more here: www.science.org/doi/10.1126/...

Wonderful popular science article on using buried fibers to do interesting science. There’s also a nice description of my work at Caltech imaging the SoCal Moho and of what we’re trying to do at the USGS with a fiber in southern Cascadia. Worth a read!

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/...

New paper out! Last chapter of my PhD. We made a long-term seismicity and MT catalog for Ridgecrest using a state-of-the-art workflow. We then used the catalog to make new insights on the stress evolution throughout the sequence using point process theory. Check it out here: doi.org/10.1093/gji/...

Nice overview of our recent paper for Caltech news:

DAS meets the Moho! New paper in Science Advances w/ Zhongwen Zhan. We developed a method for finding Moho reflections in DAS data. One event can yield 10s of km of fine-scale Moho depth measurements. We applied it to dozens of SoCal events and learned a lot about the Garlock, Coso, and more.

So glad there are people in this world willing to port old compiled codes to python. Often thankless but super impactful work.

First post is a plug for our new paper on the Cascadia SZ led by Hao Guo. We carefully relocated events in the Gorda slab and computed their source parameters. Our results suggest lower effective stress in the slab crust and, by extension, the megathrust! Check it out here: doi.org/10.1785/0220...
