PUBLICATIONS Journal of Geophysical Research: Solid Earth RESEARCH ARTICLE Seismogeodesy of the 2014 Mw6.1 Napa earthquake, 10.1002/2015JB011921 California: Rapid response and modeling of fast Key Points: rupture on a dipping strike-slip fault • Seismogeodetic data can provide rapid earthquake models Diego Melgar1, Jianghui Geng2, Brendan W. Crowell3, Jennifer S. Haase2, Yehuda Bock2, • Rupture is fast on a dipping strike 4 1 slip fault William C. Hammond , and Richard M. Allen • The surface trace is likely not the 1 2 extension of the fault plane Seismological Laboratory, University of California, Berkeley, California, USA, Cecil H. and Ida M.

Melgar, systems during medium to large events. The 2014 Mw6.1 Napa, California earthquake is important because it
[email protected] provides an opportunity to study an event at the lower threshold of what can be detected with GPS. We show the results of GPS-only earthquake source products such as peak ground displacement magnitude scaling, Citation: centroid moment tensor (CMT) solution, and static slip inversion. We also highlight the retrospective real-time Melgar, D., J. Geng, B. W. Crowell, combination of GPS and strong motion data to produce seismogeodetic waveforms that have higher precision J.
