Project Abstract
 Converted seismic phases generated by nine deep events beneath or near the Los Angeles Basin (LAB) are used to determine the depth of the LAB by mapping the S-P conversion points. The preliminary results show that the Central Trough of the LAB is 12-14 km deep at its lowest point, which is significantly deeper than the previously assumed value of 9 km (Wright, 1991).
Intellectual Merit The project contributes to improving the SCEC velocity model through a better definition of the Los Angeles basin.
Broader Impacts This study partially support the PhD activity of a graduate student at Caltech.
