Earthquake early warning systems can provide crucial warning that strong ground shaking is imminent in the event of a large earthquake. In our recent open-access paper, @nvseismolab.bsky.social scientists study the potential for earthquake early warning systems in Nevada.

An important problem in seismology is to use the spatial "radiation" pattern of earthquake ground motion to infer fault plane geometry. This new study develops and systematically tests different ways of using S/P amplitude ratio data to more accurately infer focal mechanisms. doi.org/10.1785/0220...

Accurately measuring earthquake size is one of the most important tasks in seismology, but is surprisingly difficult for small earthquakes. NSL PhD student Annie Patton used seismic coda - the extended ringing / shaking after direct phase arrivals - to measure sizes of small earthquakes in NV.
🚨New paper alert 🚨
PhD candidate Annie Patton (UNR) shows that in calculating Mw for small earthquakes using spectral fitting, it’s particularly important to have well-constrained estimates of depth and apparent stress. Co-authored with an amazing team!
