Temporal and spatial relationships suggest that inflation within the Long Valley Caldera is a likely mechanism for fault plane rupture in the Hilton Block.

Modeling suggests that the orientation of sinistral strike-slip fault planes in the Hilton Block are possible given a combination of the Langbein et al. 1993 estimation for regional strain and a high values for the coefficient of friction.

Aerial photography and rupture geometry advocate the significant development of fault planes and surficial expression in the Hilton Block.

Previous geologic mapping of the area indicates NW trending fault structures, while seismic data reveals active NNE trending lineamants.
