Toward Earthquake Early Warning in Nevada
Description:
Nevada is one of the most seismically active states, with numerous active fault systems across the state and in bordering regions. Nevada has a notable history of large, M 6 and greater, earthquakes and increased risk due to the most populated areas lying in some of the most hazardous sections of the state. Earthquake early warning systems aim to lower the risk of earthquakes by sending alerts to potentially affected people before shaking arrives at their location. ShakeAlert is the current EEW system in place in the U.S., but it only operational in the West Coast states of California, Oregon, and Washington at the moment. Our research is focused on testing the feasibility of Nevada’s seismic network for EEW and determining what changes to the network or EEW processes might be needed for ShakeAlert to expand to Nevada. The results obtained for Nevada could also provide new insights into EEW that can be applied to other parts of the US. Using hazard maps and current network configurations, we created upgrade scores to qualitatively show the current state of the network and the locations where adding new stations would lead to the most improvements. We explore this further using grids of potential new stations and simulated earthquakes to test the effects of adding new stations to the current network. One aspect of the ShakeAlert workflow is estimating the magnitude of an earthquake as it occurs using the peak displacement measured at individual stations. This relation was created using a limited data set that did not include Nevada earthquakes, so we are testing whether this relation holds true in Nevada or if a new regional relation needs to be created. We are also looking at using site terms and studying trends across geographic groupings to improve accuracy.
