Kendra L. Johnson, Gavin P. Hayes, Robert B. Herrmann, Harley M. Benz, Daniel E. McNamara, Eric A. Bergman
2016, Geophysical Journal International (206) 525-556
Modern tectonic studies often use regional moment tensors (RMTs) to interpret the seismotectonic framework of an earthquake or earthquake sequence; however, despite extensive use, little existing work addresses RMT parameter uncertainty. Here, we quantify how network geometry and faulting style affect RMT sensitivity. We examine how data-model fits change with...
