Intellectual Merit
|
The deeper structure of two blind thrust faults flanking the LA trough has been explained by two competing structural models: fault-bend folding and steeply dipping reverse faulting. We use petroleum-exploration well data and multichannel seismic profiles, to argue for the latter model: that the Compton - Los Alamitos structure is a fault propagation fold, and the NE-bounding structure to the Newport Inglewood fault zone. Our findings suggest the NIF and CLA partition strike-slip and vertical deformation across the western LA Basin. |
Broader Impacts
|
Our findings have major implications for the seismic hazard of the Los Angeles basin. This project also supported the training of Danielle Verdugo in the interpretation of oil well data. Ms. Verdugo will use her training to characterize the subsurface structure of the Los Alamitos strand in the vicinity of the 1933 Long Beach earthquake. |
