Project Abstract
 INTERIM REPORT: Current progress: (1) Using spectral ratio method, completed analysis of Ridgecrest sequence, and obtained complexity ratio; (2) Using stacking method, completed analysis of foreshocks of the Ridgecrest sequence; (3) Performed preliminary comparison at AGU fall 2021 annual meeting. Project extension requested, to be completed in fall 2022. Final report is to be submitted in March 2023.
