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. doi.org/10.1785/0120...

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...

Happy to share newly published work by recent @nvseismolab.bsky.social alum Avi Chatterjee developing machine learning workflows to characterize small earthquakes and the associated crustal stress field in southern Nevada: 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.

A shaky day for us here in Nevada with a M5.5 earthquake NNE of Yearington at 3:08pm. Did you feel the shaking? Report it here earthquake.usgs.gov/earthquakes/...

Despite its importance, earthquake magnitude is a surprisingly ambiguous concept. Here we combine analysis of a large dataset of earthquakes in the western US with synthetic experiments to understand the relation between different magnitude scales. pubs.geoscienceworld.org/ssa/tsr/arti...

Locating earthquakes is a fundamental task in seismology with many important applications, but is not always as easy as it looks. Here we @nvseismolab.bsky.social published a new catalog of high-precision earthquake locations for Nevada and the surrounding region. doi.org/10.1785/0220...
